Knowledge is power; have fitness trackers finally tipped the scales in the weight loss battle in favor of a gadget that might actually work as advertised? The fitness industry is flooded with gadgets, devices, and all kinds of equipment aimed at making the process of getting into shape faster, more effective, efficient, and, hopefully, an enjoyable process. From ab rollers claiming to make crunches more effective to the deplorable and dirty-looking shake weight to the dangerously dehydrating sauna suits, those who engage in exercise have been searching for an edge. At some point, most people have ended up wasting money on at least one gimmick in hopes of finding that magic bullet.
Now trackers are becoming the go to device for anyone interested in monitoring their personal biometrics-literally, measurements of life. These devices can measure a wide variety of physical activities including, but not limited to, daily steps, calories burned, heart rate, and sleep patterns. Sounds good, a small piece of technology that can be conveniently toted around, tracking your life and physical activity. The standard method of wearing an activity tracker is either around the wrist like a watch or on a belt clip.
So what does a health conscious person need to know about this bit of technology? To begin with, this is not new technology. These devices originally started hitting the market during the 1980s in the form of pedometers, or step-counters. In fact, the technology known as accelerometers is the same technology in smartphones that allows the screen to switch between vertical and horizontal viewing.[i]This technology is not new in and of itself. What is new is the faster computer processing technology and memory capability that makes these fitness trackers capable of tracking more than the number of steps a person takes.
But just how accurate are they? Upon a quick search of Amazon.com, I found more than twenty different manufacturers of fitness trackers offering nearly 100 different models to choose from. With prices ranging from $25 to upwards of $200 how does person pick the right tracker? There is little research to verify the accuracy of these devices.
In fact, there only two published studies examining the accuracy of these devices. The first was done at Iowa State University and published in September 2014.[ii]Of the roughly100 commercially available fitness trackers this study only eight models were tested: Bodymedia FIT, Fitbit Zip and Fitbit One, Jawbone Up, Actigraph, Directlife, Nike Fuel Band, and Basis Band. The second study was conducted by the American Council on Exercise and published on their website this month[iii] this study looked at five different models: Nike + Fuel band, Fitbit Ultra, Jaw Bone Up, Bodymedia Fitcore, and the Adidas MiCoach.
Both studies evaluated the trackers ability to accurately measure steps. The ACE study also looked at calorie expenditure while walking and running. These measurements were then compared to research quality pedometers, NL-200i, and metabolic gas analyzers. When it comes to measuring step, both the BodyMedia and FitBit brands proved to be the most accurate coming within 90-91% accuracy of the research models. The Nike Fuel Bands came in at around 13% while the rest of the models varied between 15-20% accuracy. When it comes to accurately gauging calories burned through exercise The Jawbone model led the way with 87% accuracy while walking. The caveat here is that as intensity and variety of exercise movements increased the accuracy of gauging caloric expenditure went down.
The take away from all of this is pretty simple: the technology is a great step forward in giving people a convenient way of receiving reasonably accurate, but not perfect data, for measuring physical activity. This is especially true for people who do not regularly exercise or only exercise utilizing light activities such as walking. For those who are avid runners, strength training enthusiasts, or high performance athletes, the technology is better than being clueless but still has room for improvement before being considered a gospel of health. The greatest benefit will be in helping sedentary people realize how true inactive they are. Sitting for several hours a day and then engaging in 30 minutes of exercise may not necessarily make a person “active.” In the regard fitness trackers are an excellent educational tool for helping people better understand how to strike a balance between the calories expended through metabolism and physical activity versus calories consumed through diet.
So what would I recommend? I do not personally own one, however, based upon the research I would being looking at a tracker from either Jawbone (who purchased BodyMedia after the ACE study was conducted but before it was published), FitBit, or one of the Nike Fuel Bands. I also would not go cheap, buying the best model I can afford. If the research has indicated anything through this, it is that a person will get what they pay for with this technology. If I was to invest in one of these fitness trackers, I would not skimp on the quality to save a few bucks.

Plans fail for lack of counsel, but with many advisers they succeed. Proverbs 15:22[i]
The first step in avoiding the fate of the resolutioner is to have a plan. All of the enthusiasm in the world will not carry the healthy resolution out of January and through the rest of the year if it lacks a solid plan. A plan bridges the gap between identifying what you want and getting there. Most importantly, a plan puts purpose into the passion and directs the course of the action into a verifiable outcome.
If success is to become reality, there are several steps to creating a fitness plan that need to occur before embarking upon the journey to a healthier life. Take the first step by completely abandoning the notion of the New Year’s Resolution. Resolutions fail, plain and simple, resolutions are a stupid waste of time. Click here if you want to know why. Do yourself a favor and truly commit, until you do life-changing progress will never happen.
Changing your life takes time so get real about the time commitment involved: how many hours and days per week can you really commit to exercise? An honest answer will directly influence the expectation of how long it will take to hit the big goal. Are you trying to lose weight? It is healthy and possible to lose up to 2 lbs per week. If you want to lose 20 lbs it is possible to do that in about ten weeks. However, for most people, that requires exercising or other physical activity for at least one hour per day every day of the week. Do time constraints prevent you from committing to that? If so,then adjust your expectations and accept slower progress with a more delayed completion date. Slower progress is still progress. It is also more permanent.
Permanent change requires prioritizing nutrition over exercise. It is proper and healthy nutrition that changes the body. Exercise helps speed the process along. If forced to choose between the two, choose to focus on eating healthier. Healthy food is found on the farm, not in a factory.
Get the most of exercise by training with a purpose. What I mean by that is simple: pick activities outside of the gym that require a certain level of fitness and are enjoyable. Build an exercise program around the idea of making that activity a better experience. One of the easiest ways to ensure that you will stick with an exercise program is see the improved fitness translate into improved performance in other areas of life. Do not make the mistake of exercising based upon what the popular trends are or what friends may be doing. That is buying into marketing, not making a personal choice. One of the most misunderstood, but most important points, of exercise is that you become a better you. Not a better version of a model, celebrity, or your fit neighbor. A better you. Exercise for that purpose and success will come.
When success does come enjoy a little reward, a program without incentives and recognition of accomplishments is doomed to failure. I would caution against using food as that reward, especially if fat loss is the primary goal. It is too easy to have a “cheat” meal and then feel guilty and scrap the program for days, weeks, or the rest of the year. Was body fat lost? Go buy a new outfit. Or go do that adventure that may have been impossible before. Be deliberate about the reward process but do not go crazy. Leave the reward slightly unsatisfying so that the desire for further progress and greater reward remains. Those who continue to pursue improvements are those who learn to make peace with never being fully satisfied. The moment a person decides that satisfaction is completely met is the moment that person quits trying and progress ends.
Continual progress requires a plan that gradually becomes more challenging. A comprehensive plan will address the obstacles of a positive reward system, training with a purpose, prioritizing nutrition, and understanding time commitment. Create this plan and the resolution will become reality.
Setting a goal is not the main thing. It is deciding how you will go about achieving it and staying with that plan.-Tom Landry

How do you go from where you are to where you wanna be? And I think you have to have an enthusiasm for life. You have to have a dream, a goal. And you have to be willing to work for it.
Consider this my fitness year in review article. Almost a year ago to the day, on December 13, 2014, I sat down and outlined six personal goals for improving my fitness level. In particular, I decided to focus on improving my maximal strength while improving conditioning by making these six goals my target. In you want an in-depth look at my 2014 goals, go here,. I will briefly outline them in this post. My six goals were:
1. Maintain Bodyweight between 170-180lbs. Failed
2. Perform the “Good Morning” strength exercise with my body weight for 10 repetitions Accomplished in September
3. Deadlift 350lbs. Accomplished in July, Smashed in December
4. Back Squat 400lbs Accomplished in December
5. Hang Clean my body weight for sets of 10 Accomplished in October
6. Meet the Sprint Protocol Outlined in the Original Post Accomplished in November
It should be noted that with the Good Morning, Deadlifts, Back Squat, and Hang Cleans that I do these exercises without the assistance of a weight belt. The reasoning is simple: the weight belt, while it does help improve the amount of weight a person can lift on certain exercises, is filler for poor form and muscular weakness. My personal feeling is that maintaining correct form with slightly less than maximal weight is both safer and more productive for long-term strength improvements than using the assistance of a belt to lift heavier weight, while sacrificing form, than one could safely do without it. Others may disagree with me; however, I am not just interested in being healthy and strong while I am young. I want to be doing this when I am eighty. I will take slower and safer progress for the sake of long term activity.
So how did I do with these goals? I smashed numbers 2, 3, 4, 5, and 6 while I utterly failed number one. I underestimated the muscle gain that would accompany the strength gains. I am ending 2014 at around 195lbs, most of which should be straight muscle gain. How I am I confident of this? I am anal about tracking my caloric intake and monitoring body composition changes in light of my goals. It pretty simple: the shoulder, arms, and chest of my shirts are tighter while the stomach area and waist of my pants has gotten a little smaller during the time that the scale has been reading heavier. I am not complaining about this one bit. But I did ‘fail’ this particular goal.
If you have followed my blog at all in the past, you may notice that discussing goals is becoming a reoccurring theme. I truly believe that having clear, well-defined, written goals with a specific deadline is a powerful thing in any area of life, but especially when focusing on health and fitness. After eight years of working in the fitness industry I have become convinced that people struggle and fail with any and all kinds of programs because they never make the effort to establish a solid goal prior to beginning.
Now it is time to ask yourself a question, do you feel like 2014 was a productive year in terms of improving your personal health and fitness? Did you set a goal at the beginning of the year? If so, most likely that goal was accomplished or, at the very least, noticeable progress towards accomplishing the goal was made. One of the often unrecognized benefits of having clearly defined goals is that they help hold a person accountable to staying on task. This enables a person to remain more focused on a deliberate process that will bring about the completion of the goal. Going back to my list, notice that with the exception of number four, all of my goals were completed ahead of schedule. Going into the year, I knew that the four hundred pound back squat would be the most challenging of the goals to achieve. I am not surprised that it took the longest to accomplish. But even the hardest challenge was overcome because I made it a clear and written goal with a deadline.
I often talk with people whom are frustrated with a lack of progress and feel like they are wasting time when it comes to exercising. Most people have an idea of what they want put no clearly defined goal. A goal is a target, something at which to aim. But if a person is not aiming at something specific then that person will miss: every single time. Do you want 2015 to be better than 2014? Figure out what you want to accomplish and set a specific deadline. Only then will you be able to look back and see what has been accomplished.

The pursuit of a healthy lifestyle is often filled with wacky attempts to make results while avoiding hard work. Everyone wants the results but no one really wants to work for it. Sound familiar? But instead of calling things what they are: misguided and unrelatable to anything remotely scientific, we call them Trends. The vast majority of trends, dietary- or exercise- related, are a load; so let us take a look at six so-called healthy trends that not validated by science.
1. Meatless Monday this has become so popular that some schools now have a Meatless Monday menu in elementary schools.[i] Apparently protein is now the dietary devil despite the fact that there is overwhelming evidence that high protein diets aid in weight loss. Now why is this? Dietary protein is chemically different than dietary fat or carbohydrates in that it contains a nitrogen molecule as a part of the amine group that gives rise to the amino acids. Do not worry if that went over your head. The important part of this is that the breaking of the amine group during the digestion requires greater energy expenditure than the digestion of fats or carbs. How much more? About 30%, depending on the source of the protein. Animal proteins require more energy to digest than vegetable proteins. So if a person wants to lose weight restricting calories to a healthy level combined with having those calories come from predominantly high protein sources is an easy way to lose weight. Good luck doing that without eating meat. As a personal trainer, I have never met anyone who ever said, “Can you help me look like that vegetarian over there?” Beyond weight loss, protein is a key component in building and maintaining healthy cells in every part of the body: skin, hair, internal organs, bones, and muscles. Without protein these cells cannot function properly or, when needed, be replaced. I am all for eating a healthy dose of fruit and veggies but strict vegetarians are not the healthiest people in the world.
2. Juice Cleanses Fruit and vegetables are great; as a part of a healthy nutrition program. But not as the entire program. Everything in moderation. Juice cleanses start out feeling great during the first 24-48 hours. This is due to increased presence of all the good nutrition in fruit and vegetables including high amounts of fiber. However, once that fiber catches up with you; good luck getting out of the bathroom. Extend that juice cleanse out to a four or five days, maybe a week and things quickly change. It is hard to stay hydrated when you are dealing with IBS. Severe dehydration may become a problem. If a person sticks with a juice cleanse long enough, and in severe cases, a person may begin losing hair, seeing discoloration of the nails, experience weakness and fatigue. Juice cleanses are an unhealthy extreme that eliminates needed nutrition that comes from protein and dietary fats. By all means, eat fruits and vegetables. Eat a lot of them. But do not eat fruits and vegetables exclusively.
3. Planet Fitness I rarely call out any specific entity but when the word “Fitness” is in the name of the company and the company serves pizza to its members on the first Monday night of the month; frowns upon and has an obnoxious “lunk alarm” that goes off when people show the slightest bit of intensity; and does not allow certain fantastic exercises like squats or deadlifts then at the very least there is no truth in branding. I get the business concept; Planet Fitness wants to create an environment where people feel comfortable. It is appealing to a specific demographic: those want to be comfortable. That is commendable. However, by its very nature, fitness cannot be improved if ones primary concern is comfort. Intensity is the instigator of change and it is not welcome here.
4. Hot Classes I have theory about these: the instructor turns the thermostat way up to induce a sweat because the intensity of the exercise is not high enough to make people sweat. Hot yoga or any other physical activity performed in high heat puts the body at serious risk for dehydration. Staying properly hydrated during exercise is just as important as working up a decent sweat. Keep in mind, that if you attend these classes the sweat is more due to the heat than the effort.
5. Sauna Suits Before the trend of hot classes there was the hot suits. Those sweat suits that look like something that an astronaut might wear. The idea here is that the extra sweat increases weight loss. Let me be clear; the sauna suit does not cause weight loss by increasing metabolism and creating greater calorie burning.[ii] Any weight loss associated with the use of a sauna suit is strictly due to water loss. The weight will return as soon as a person starting rehydrating.
6. Anything that offers weight loss without effort Outside of a few specialized-physician supervised weight loss programs there is very little that will work to create weight loss without solid sweat equity. Life and health are performance-based only great effort will yield great results.

Squatting is a natural human motion. Quite soon after a toddler is able to walk unaided, the young child will begin executing perfect squat form every time the child gets down to pick something up off the floor. However, as humans age, and frankly as we spend more and more of our days sitting on our backsides, muscles begin to lose strength and flexibility that enables us to perform this natural movement pattern. If a person is unable to squat properly then that person will be unable to follow OSHA guidelines of “lift with your legs, not your back.” Elderly people who lack the physical strength to properly squat will have difficulty getting up and down out of a chair or off the couch. People do not stop moving because they grow old. People grow old because they stop moving. A properly executed squat will not cause bad knees. Not squatting, or, squatting with poor technique will cause a person to have knee problems. Squatting and deadlifting are two vital components of being able to safely and effectively move heavy loads as well as maintaining the strength to perform simple daily tasks.
There is far more to properly executing a squat than simply bending the knees and lowering the body. Before properly executing a squat under the load of weights, proper form must be mastered. Proper form begins with the width of foot positioning and the angle of the toes. Once this is established the hips must be place into a position known as the “hip-hinge.” This allows for maximizing the depth of the squat, but more importantly, it keeps the spine in proper alignment to ensure that the squat is performed safely. Once this has been done the position of the knee in relation to the foot must be monitored all the way through the squat.
There are three basic problems that arise from poor squat form. The first is the loss of the hip hinge position. At whatever point in the depth of the squat that this position is lost, the squat should be stopped. This is incredibly important when executing the squat with any kind of resistance. The loss of the hip hinge allows the backside to tuck underneath the hips. This position is referred to as “butt-wink” and the result is a rounding of the lower back. Under a heavy load, this rounding of the lower back places an incredibly dangerous stress on the spine which may lead to an injury such as a bulging disc or crushed vertebrae. The cause of this is usually weak muscles in the lower back and glutes combined with tight hamstrings. The best strengthening exercise for this is a Reverse Hyper Extension used in conjunction with the Standing Hamstring Stretch.
|The "Butt-Wink" results in a rounded back. Very unsafe when squatting under load.|
The second problem with squat form is a lifting of the heels off of the floor. This is a direct result of tight hamstrings and calves. Under no circumstances should the heels ever come off the floor. The heels should remain flat with the body weight over them; when standing out of the squat, visualized driving the heels through the floor to help maintain proper contact with the ground.
The final technique problem with squatting related to the position of the knees over the feet. The knees should remain directly over the feet throughout the squat. If the knees start to cave inward at any point it indicates weakness in the glute medius and minimis, which are the primary muscles responsible for holding the hips out from the body, allowing the hips and legs to stay in proper alignment during the squat. If this is a problem two exercises must be done to correct it.
A properly executed squat is a fantastic method of developing total body strength and mobility. However, failing to properly master the technique, or using weight that is too heavy to allow proper technique is a set up for pain and, potentially, a debilitating injury. Master a proper squat and get some life back in those legs!

The fitness industry is saturated with negativity: don’t this or that, that exercise hurts your knees, this one is bad for you back, your form is bad, you will hurt yourself. YOU CAN”T DO IT. For an industry that is supposed to be about helping people become healthier and be better it sometimes feels like the fitness media, some professionals, or sometimes friends and family seem more bent on telling what we cannot do rather than focusing on helping us discover what we can do. Idiots, I say that in the most loving way possible, but still, idiots.
There is a simple solution for these kinds of people or forms of influence in your life. Ignore them and minimize contact with them. If that is not possible then surround yourself with enough positive voices to drown out the few negative ones and remember these words:
It is not the critic who counts: not the man who points out how THE STRONG MAN stumbles or where the DOER OF DEEDS could have done better. The CREDIT belongs to THE ONE who is actually IN THE ARENA, whose face is marred by dust and sweat and blood, WHO STRIVES VALIANTLY, who errs and comes up short again and again, because there is NO EFFORT WITHOUT ERROR or shortcoming, but who knows the great enthusiasms, the great devotions, who spends himself in a WORTHY CAUSE; who at best, knows in the end, the TRIUMPH of high achievement, and who at worst, if he fails, at least he fails while DARING GREATLY, so that his place shall NEVER be with those COLD and TIMID SOULS, who knew neither victory nor defeat.- Theodore Roosevelt
When my weight loss journey began as a teenager, I put that quote up in my bedroom to remind me that the critics do not count. Too many times people misunderstand success, and in doing so, allow the failures of others to predestine their own failure. This is a major mistake. People criticize what they unable to do for themselves. Critics are absolutely useless; forget about them. Along the way, these experts at failing will explain and reason away why they failed. When someone starts into a litany of why you cannot succeed, remember, that person is telling their story of failure, not yours. You will not have story of failure because you will succeed. Success comes because you understand something that the bitter failures do not.
Success comes to those who do not compete with others but instead compete only with themselves. This is the only way to avoid jealousy. It is the only way to become better instead of bitter. The competition is the person in the mirror starring back at you. Become better today than you were yesterday and every day you will be winning. “The greatest fear in the world is the opinions of others, and the moment you are unafraid of the crowd you are no longer a sheep, you become a lion. A great roar arises in your heart, the roar of freedom.”-OSHO
Life is performance based. Results come to those who make an effort, not excuses. Successful people are not gifted with some secret talent or ability. They work hard and succeed on purpose. The success comes because they have learned to ignore the critics and get back up after getting knocked down. People who criticize fail because they thought success is about how high a person can climb. It is not, success is persisting despite the odds going against you. Sound uncomfortable? It is, and successful people learn to fall in love with discomfort because discomfort is the catalyst of growth and change. Negative people do not win at weight loss because they are unwilling to become uncomfortable. So they never experience growth.
Move out of your comfort zone. You can only grow if you are willing to feel awkward and uncomfortable when you try something new. - Brian Tracy
Negative people refuse to take action, so they never go anywhere, try anything or ever experience progress. Success is directly tied to action. There may be mistakes along the way but successful people do not quit.

If I mention core training and you think “six-pack” you will never have a set of well-defined abs. The area of the body referred to as the “core” is far more than the Rectus Abdominus or “six-pack” muscle. Most people have the idea that if the Rectus Abdominus is being worked then core training is complete. The majority of people confuse training the functionality of the core with having visible abs. Training the functionality of the core muscles is about improving total body stability, strength, and power. Ultimately true core training leads to improved coordination, balance, and athleticism. Training for visibly defined abs leads to errors, confusion, and frustration. There are 168 hours in a week. If a person spends five of those hours exercising, that leaves 163 hours to completely undo what happens in the gym. The visibility of the abs is the result of a highly-controlled diet. Every body has a muscle structure of the “six-pack.” However, most people never see their abs because they cannot but down the fork and back away from the table. Abs happen in the kitchen, developing the core happens in the gym.
The primary function of the core muscles is to keep the spine in the proper, upright position. Proper spinal alignment is the key to healthy, pain free movement of the human body. Traditionally, when people think “core” they think of muscles collectively on the front of the body in between the bottom of the chest and the waist. These muscles include the Rectus Abdominus, transverse abdominals, Internal and external obliques, serratus anterior, rectus sheath, and linea alba.
But the muscles of the core are dedicated to the task of keeping the spine properly aligned and the spine runs from the base of the skull down into the pelvis. Along the backside of the body, starting with the base of the skull and down to the pelvis, there are several muscles: sternocleidomastoid, splenius capitis, levator scapulae, trapezius, rhomboids, erector spinae, spinalis thoracis, longissimus thoracis, serratus posterior, and quadratus laborum. That is just the muscles of the back. As I said earlier, the spine goes all the way into the pelvis. The pelvis is stabilized by the gluteus maximus, gluteus medius, gluteus minimus, the adductor and abductor muscles, tensor fasciae latae, satorius, pectineus, and illiopsoas. All of those muscles, more than thirty in total, work to stabilize the spine to keep the body in proper alignment. Sound confusing and complicated? It is not; understand that crunches alone are not going to cut it here.
An injury or strength imbalance in one or more of these muscles will prevent the spine from staying in proper alignment. A minor problem will result skewed movement and a loss of strength and balance. A severe problem may leave a person in debilitating pain that makes life very difficult. Stability throughout the muscles of the abdomen, neck, back, and hips leads to ease of movement, better balance, and fluid movement. The stability of these muscles can easily be trained by any activity that challenges balance. Exercises such as lunges, split squats, forearm planks, side planks, bridges, bird dogs, and a few yoga poses are all excellent ways to train the stability of these muscles.
Stability and support of the spine is the most important function of the core muscles, however, these muscles also form the foundation of total body strength and power. In everyday life and in athletics, a weak core will limit the body’s ability to utilize its strength. The core controls movement of the body through three primary movements; spinal flexion, spinal extension, and rotation. For optimal mobility and athleticism all three of these movement patterns must be trained. Training these movement patterns with a properly balanced program is vital for maintaining proper posture and mobility.
For any person that has tried exercise the crunch probably was a part of the program. Spinal flexion is controlled by the rectus abdominus muscle. Anyone who has performed a crunch or leg raise has done an exercise that moves through spinal flexion. The problem with this is that most people spend all day seated behind a desk. Being in the seated with poor posture puts the body in a position of constant spinal flexion. For most people, training the body through more exercises that encourage spinal flexion is a set up for serious posture problems and pain. Unless a person has body fat levels low enough to have visible abs, 12% or less for men and 18% or less for women, than exercises such as crunches are usually not worth the time and effort.
It would be in the best interest of most people to train exercises that work through spinal extension to counteract the effects of prolonged periods of sitting. A prioritization of the muscles of the hamstrings, glutes, and back is necessary to improve core stability, strength, and mobility. Collectively these muscles are known as the Posterior Chain. It is these muscles that often grow weak as a result of long periods of sitting. As these muscles weaken over time strength imbalances begin that lead to deviations in proper spinal alignment and posture. To counteract this, an emphasis should be placed on training spinal extension. Think of it this way, if you cannot see the muscles when you look in a mirror, training it should be a priority. Most people only train what they can see. That is a mistake. Exercises such as rows, band pulls, back extensions, deadlifts, glute-ham raises should be trained more often than anything the works the muscles on the front of the body. A ratio of at least 2:1, for some people maybe 3:1, of posterior chain and spinal extension to spinal flexion exercises would be appropriate. Personally, I never do crunches, I spend enough time sitting that I do not want spend any time training through the spinal flexion motion.
The final primary movement of the core muscles is rotation. This is primarily controlled by the internal and external obliques, which also make some contribution to spinal stability. While rotational training may have little carryover to everyday life, it is vital to almost any athletic pursuit. Try hitting a golf ball or throw a baseball without rotational strength; the results will be less than impressive. For the average fitness enthusiast, the rotary torso machine, cable rotations and medicine ball twists are adequate exercises. But for someone wishing to improve athletic performance it will be necessary to get off the floor and really train to rotate explosively; Heiden jumps, rotational medicine ball tosses, and suspended rotations with a TRX band will all develop rotational strength while improving stability.
A properly functioning core in more than just the abs and requires more than crunches to properly train it. Stability, mobility, strength, power, and athleticism are all influenced by and limited to the functionality of the core muscles. Structuring a training program to eliminate strength imbalances and improve posture is a necessity for anyone who wishes to maximize their body’s potential. Alone, crunches will not cut it.
