Bodyweight Blitz


Bodyweight Blitz
                Bodyweight training has grown has popularity over the last few years, particularly within the realm of the at home workout DVD.  P90X, Insanity, Zumba, and Tae Bo, just to name a few, are among the best-selling fitness programs ever.  The common element of all these programs is that the individual person’s own body is providing the resistance.  So the question is: can body weight alone provide enough stimulation to increase a person’s overall fitness, or are programs like this just a bunch of clever and gimmicky marketing?  And, why not?  There are several advantages to this type of training.  My apologies for sounding like an infomercial:
·         Convenient:  Body weight training can be done virtually anywhere, including at home, no gym required
·         Improved overall Conditioning: Strength, Coordination, Increased Muscle-Mass, Fat-Burning, Endurance, and Quality of Movement can all be improved by training using body weight as a resistance
·         Very little space required: don’t waste space by cluttering it up with bulky equipment
·         No Spotter Needed: It is safe to do by yourself
·         Combine Strength Training with Endurance Training

The short answer is: YES.  Body weight conditioning can be a great way to build a program by itself or as an addition to a weightlifting or cardio-based program.  The great thing about body weight training is that it improves Functional Strength.  That is a term that has been thrown around a lot the last couple of years without a lot of clarity given to what that means.  To say that training is creating an improvement in functional strength means that the training activities being performed mimic a specific movement pattern of a sport or other physical activity.  This is more than just being able to perform an exercise with heavier weights or the same weight for more repetitions; it is direct improvement to the quality of movement on the playing field during the competition.
               
Just about every person’s fitness goal falls into one of six categories: hypertrophy (muscle-building), maximum strength, maximum power, maximum speed, fat loss, and endurance.  A training program can be designed to maximize any one of these goals and there is some overlap between some of the goals.  However, any program based in body weight training or not, should be created with the intention of focusing on primarily one goal at a time.  The key to successfully utilizing body weight training to accomplish these goals is to understand four things: 1) Appropriate repetition range or time duration for activity; 2) Appropriate Rest Period; 3) Work to Rest Ratio; and 4) Real-life training examples.  The table below outlines how to classify and design a program aimed at achieving these goals.  It is important to understand, when designing a program that having the right balance of repetition ranges, time durations, and rest period maximizes the efficiency of training for the desired goal.

The key to reaching these goals using body weight training is identifying the primary goal and design workouts using the appropriate protocol.  One of the problems that people run into with body weight training is that body quickly adapts to moving itself.  Without increased stimulation a body weight exercise that may have originally started as a power exercise can quickly turn into an endurance exercise. 

Take a box jump as an example; it is great exercise for improving explosive lower body power.  The box jump is performed by starting on the floor, and with both feet together, jumping on to an elevated platform.  To perform this exercise to improve power, a person would only need to complete 1 to 3 repetitions or for less than 15 seconds. Resting 3 to four times longer than the amount of time required to perform the activity.  Performing the exercise for more than a few repetitions or shortening the rest period would change this from power training into hypertrophy training; enough repetitions or inadequate rest periods when turn this into an endurance exercise.  When training for power increasing the number of repetitions per set or increasing the time duration of the set is counterproductive.  To increase power with a box jump, increase the height of the jump, not the number of reps.

A bodyweight workout does not have to target just one goal; it can target two goals.  A well designed bodyweight, power based workout can actually be designed to train three or more goals.  Here is how to do that.  Keeping the primary goal as power training, the second goal will be fat loss with the third goal being endurance.  To accomplish this, the workout will be designed as a circuit, training the entire body in one workout.  This will allow the workout to train for power while keeping the body moving enough to burn plenty of calories for fat-burning and building endurance.  Perform each exercise for the desired number of reps, rest for the specified time, and then begin the next exercise.  Follow this pattern until all exercises have been completed.  Doing this will allow adequate rest for the muscle groups to meet the intense demand of the low repetitions while keeping the body moving with short rest between exercises, creating a fat-burning effect.  To build endurance, simply complete as many rounds as possible.  Remember to follow the designated rest periods.  Eliminate the rest periods will turn this into a strictly endurance workout.  Prolonging the rest periods will eliminate the power training aspect.

Box Jumps
Begin by standing with the feet shoulder-width apart.  Lower into a squat while simultaneously swinging the arms back behind the body.  Explosively swing the arms forward while at the same time jumping and lifting both feet off of the ground, and, keeping the feet shoulder-width apart, land on the platform with both feet at the same time. Upon landing lower into a squat to cushion the pressure of the landing, then, step of the platform, one foot at a time, or, jump off with both feet together.  If jumping off, lower into a squat upon landing to cushion the pressure.  That is one rep.
Skater Jumps
Begin by standing with the feet shoulder-width apart.  Jump to the right as far as possible and land on the right foot with the left foot off of the ground.  Jump back to the left, landing on the left foot with the right foot off of the ground.  That is one rep.




TRX Push Ups
Adjust the TRX straps so that the handles are level with the knees.  Firmly grasp the handles and place the body into the top of a pushup position.  Lower the body into a push up and the press the body back to the top of the push up position.  That is one rep.



TRX Pull Ups
Adjust the handle length of the TRX straps until they are level with the chest.  Grasp both handles firmly and walk the feet forward until the handles are positioned directly above the chest.  Keep the body in a straight line from the head to the toes.  Contract the muscles of the back and pull the body up until the chest is directly underneath the handles. Return to the start position.  That is one rep.

Bodyweight conditioning is a great tool to have in your fitness tool bag.  It is a great way to build an entire program or works as a substitute for those times when you are too busy to get to the gym.  If your program is stuck in a rut consider adding body weight training into the mix.  Below is a list of fantastic body weight exercises that can be adapted to meet any training goal.

No results? It might be that your cardio training sucks


                Are you one of those people who spend countless hours on a treadmill, bike, or elliptical and is completely frustrated by a lack of change in your body: an inability to lose weight, change sizes, or otherwise fail to see improvements when you look in the mirror?  Do you wonder why other people seem to get into shape or lose weight faster than you?  Would you like to know how I, as an obese teenager, lost one hundred pounds and have kept it off for the last fourteen years?  I can tell you that I, and probably no one who looks how you wish to look, or has lived a life time at a healthy body weight, accomplished it in the cardio section of your local fitness club.  After seven years working in the fitness industry, and fourteen years being in and out of gyms as both a member and employee, I have come to the conclusion that the floor space is occupied cardio machines is generally a waste of time for the average gym-goer.
                Here is a little secret that most gym owners may not understand and equipment manufacturers do not want you to know: those cardio machines are not as effective as the manufacturers claim to be.  The reason is simple: these machines do not activate and recruit the use of muscle tissue nearly as well as performing the same activity outside.  Take the treadmill as an example: the belt moves backward while your foot comes forward with each walking step or running stride.  Now, if a person walks or runs outside, every foot strike results in tension being created as the muscle of the calves, hamstrings, and glutes as these muscles fire to propel the body forward.  The foot comes off the ground, and upon the impact of the next step, the quadriceps fire to slow the body’s momentum enough that you do not go falling head over heels.  This is what happens when the body is propelled along the solid ground. 
The problem with doing this on a treadmill is the backward motion of the belt.  This backward motion of the belt drastically reduces the use of the hamstrings and glutes from creating movement.  By the way, the glute muscles are the most powerful muscles in the human body.  The stronger a person's glute muscles are, the fitter and faster that person is.  When it comes to health and maximizing fitness, you should like big butts and that is no lie.  Alright, back to the lesson in biomechanics: essentially, a treadmill cuts the muscle involvement in walking or running almost in half.  Half of the muscle recruitment translates into half the work performed by the body so roughly half the calories are burned during time spent on a treadmill as opposed to the same activity performed outside.  Wait, what? 
Pay attention here: for the reasons I just explained, the calorie count on cardio machines is off.   Using a cardio machine only burns about half the calories the little computer tells.  Why is that?  The computers in cardio machines create an estimation of the number of calories burned based upon mathematical equations.  The problem is those formulas are based on energy expenditure for performing the activity outside, not on the cardio equipment.  So, with less muscle involvement, activities performed on cardio equipment are less intense than the same activities performed outside.  Lower intensity means lower number of calories burned resulting is far slower, if any, progression towards a healthier, fitter body.  I have used the treadmill as an example but the same principles apply to almost every piece of cardio equipment.  There are a few ways to overcome this problem.
Obviously, the best option is to take cardio activities like walking, running, and biking outside.  Now, if you do not like that idea or if the weather will not cooperate there are some simple solutions to improve the quality of those cardio workouts.
1.       Use the stair climber.  It is the only piece of cardio equipment that accurately mimics a real life activity.  For this reason is it the most challenging piece of cardio equipment in the gym. Or you can save time at the gym by taking the stairs instead of the elevators.
2.       Put the treadmill on an incline.  An inclined treadmill will increase the use of the hamstrings and glutes, making it more like walking or running outside.  The higher the incline the better.  Use a minimum of a 5% incline to create a level of muscle activation similar to walking or running outside.
3.       Increase the resistance on the bike or elliptical.  Most people simply do not push themselves hard enough on these pieces.  Increase the resistance to the point where you can feel the muscles contracting throughout every stride.  If you can’t feel the muscles contracting then you are moving more from momentum than actual physical work.
4.       Do not stay at the same boring pace for an extended period of time.  I cannot imagine anything more boring in the gym than spending an eternity strolling on the treadmill.  If the activity is not challenging or seems boring to your brain it is boring your muscles too.  Bored muscles are not receiving stimulation and do not lose weight, become stronger or leaner.
If cardio is your exercise mode of choice, get intense with it or it will not change you.  I do a sprint workout once a week for about twenty-five minutes.  This is one of two conditioning workouts that I do each week.  This sprint workout is the only time I ever get on a cardio piece.  During those twenty-five minutes I destroy more body fat than anyone who comes in and spends an hour walking on a treadmill five or six days per week.  Intensity, not duration is the key to losing body fat.  This is my sprint program, if you can’t do it at the same incline or same speed, build up to it.  Trust me; you will get faster results doing a workout like this.

The second conditioning workout I do is a body weight exercise based program.  Typically, I follow a Tabata protocol with this workout.  Tabata protocol involves performing an exercise for twenty seconds, taking a ten second break, then repeating for twenty seconds.  This continues until a total of eight rounds are completed.  This process is completed in a single four minute time period.  This four minute period is referred to a “Tabata.”  With a multiple Tabata workout it is common to take a one minute break between each Tabata.
Tabatas are a great way to add conditioning to the end of a strength training session or multiple Tabatas may be put together for a conditioning workout, like the one below.  I did this workout Friday morning before heading into the Labor Day weekend.  It is a total of six tabatas: a 30 minute workout.
Tabata 1:
·         Cable Presses-20 seconds
·         Rest- 10 seconds
·         Jump Rope- 20 seconds
·         Rest- 10 seconds
·         Complete Four times
·         One minute Rest
Tabata 2:
·         Plank- 20 seconds
·         Rest- 10 seconds
·         Battle Ropes- 20 seconds
·         Rest- 10 seconds
·         Complete Four times
·         One minute Rest
Tabata 3:
·         Battle Ropes- 20 seconds
·         Rest- 10 seconds
·         Mountain Climbers-20 seconds
·         Rest- 10 seconds
·         Complete Four times
·         One Minute Rest
Tabatas 4-6:
·         Battle Ropes- 20 seconds
·         Rest- 10 seconds
·         Jump Rope- 20 seconds
·         Rest- 10 seconds
·         Complete four times
·         One Minute Rest

Take your conditioning and fat burning to the next level with these workouts.  Remember, when it comes to losing body fat and making the body leaner; intensity is always more important than duration.  This is truer more than ever when it comes to cardio training.

Women and Strength Training

Within the culture of fitness, a terrible myth has been circulated.  It jeopardizes the potential for a woman to truly experience and enjoy everything that her body is capable of doing.  While it is slowly being defeated among the female college, professional, and Olympic athletes; this myth still runs rampant among the general population.  Every day, thousands of women walk through the doors of a local fitness club or head outdoors in pursuit of a healthier body.  Yet most remain, at best, uninformed, and at worst, incorrectly educated into avoiding a true body-reshaping activity: heavy strength training.  I believe that there are three primary reasons for this:

1.       Incredibly poor representation in the media of how weightlifting will change the physical appearance of a woman’s body.
2.       A cultural misperception that a physically strong woman cannot be both strong and beautiful.
3.       A lack of proper education and instruction that dispels the first two reasons.

Let’s dive a little deeper into those.  Over that past thirty five years or so, mainstream media, in particular body building magazines, have typically shown women who are so muscular that they look manlier than most men.  These publications feature women who professionally compete as bodybuilders in national and international competitions.  For these women, lifting weights is their full time job.  Many, but not all, of these women use anabolic steroids as part of their training.  It is because the average person gets their information from these magazines that the idea that a woman will build massive muscle size and look bulky like a man has become a false truth.  And so, reason number two came into existence: a woman who strength trains will end up looking like a man, and, therefore, lose her beauty as a woman.  This is not true, and, unfortunately, many women have bought into this lie because of reason number three.

If most women avoid heavy weightlifting for fear of developing a masculine looking body they do so without understanding a fundamental difference between the male and female body.  This difference makes it impossible for a woman to naturally develop a man’s muscle size.   There is a simple explanation for why men can increase muscle size and strength while a woman can become incredibly strong without developing the same muscle size.  The answer to this lies in the difference in testosterone levels between men and women.  Yes, women have some testosterone, but the levels are seven to eight times lower than in men.  A research study published in 2010 in the Journal for Exercise and Sport Sciences found that the higher levels of estrogen produced in women participating in heavy strength training contributed to significant improvements in muscle strength, similar to what a man could expect with the same training, but not muscle size.  Women simply cannot increase the overall size of their muscles to the extent that a man because of naturally lower levels of testosterone.

Developing incredible physical strength while remaining distinctly feminine and beautiful is not only possible; it is a reality for any woman willing to take on the challenge.  Women whom take on this challenge will discover that physical strength enhances feminine beauty.

the majority of women whom strength-train do so with incredibly light weights and perform high numbers of repetitions.  The flaw with this type of training is that it places limits of physiology of the muscles by only training one type of muscle fiber. 

There are two primary types of muscle fiber within the human body: slow-twitch and fast-twitch.  These are also referred to as Type I and Type II muscle fibers.  Each type of muscle fiber responds to a different type of training.  To maximize fitness and improve body composition a comprehension training program must emphasize training that incorporates the use of all muscle fibers at some point of the program.

Slow-twitch, or Type I, muscle fibers produce low amounts of force during contraction, a slow contraction speed, and have a  high aerobic capacity, which delays fatigue.  These fibers are best suited for long duration, cardiovascular based exercise.  The longer a particular activity lasts the more these muscle fibers are utilized and trained. The muscles receive energy from the aerobic oxidation system, one of three different energy systems within the body.  This is important to understand because the aerobic oxidation system is the slowest system for delivering energy to the muscle cells.  These muscle fibers play the dominant role in any cardiovascular-based exercise, like running or biking that lasts longer than about two minutes.  When lifting weights this system is utilized any time the weight is light enough that more than 12-15 repetitions can be completed within a single set.  This is where the majority of women tend to spend their time when weight training.  Keep this thought in mind: Type I muscle fibers typically only comprise 45-50% of the total muscle fibers within the human body.  An example of a highly trained individual who is predominantly Type I fibers would be an elite marathon runner.

Fast twitch, or type II, fibers are more complex.  There are two subtypes of these fibers: fast twitch A and Fast Twitch B.  In general, fast twitch fiber are capable of great force production, faster contractions, and power outputs than Type I Fibers.  These are the fibers that are capable of big explosive, energetic bursts of strength and speed.  Fast twitch B fibers operate using the ATP-Cr energy system which provides the initial burst of energy for high intensity physical activity.  Activities like power lifting, sprinting, plyometric training are fuelled primarily by this system and rely on the fast twitch B fibers.  Targeting these muscle fibers when weight training requires using heavy enough weight that about 1-6 repetitions are all that can be completed in a set of any given exercise.  Typically these fibers are only engaged in high intensity activity lasting less than twenty seconds. 

Fast twitch A fibers are slightly more inclined towards aerobic capacity than Fast twitch B but both are less so than Type I fibers.  The fast twitch A fibers work using anaerobic glycolysis as an energy system.  This is the intermediate energy system that supports activity lasting from approximately twenty seconds to two minutes.   When weightlifting these muscle fibers tend to be recruited using moderate weights in which 7-12 repetitions may be completed.  The combination of Type II A and B fibers make up approximately half of the total muscle fibers within the body.

So what does this mean from a training standpoint?  It means that by training with light weights for a high number of repetitions (more than 12 per set), or, just performing long duration low intensity cardio, or, a combination of the two, trains only 45-50% of the body.

In other words, by neglecting the fast twitch fibers, a woman leaves 50% of her body’s potential untapped!

Ladies, if you are wondering why it is so difficult to change your body into the lean machine you want, the answer is here: CHANGE THE WAY YOU TRAIN!  Other than improving the quality of your nutritional program nothing will change your body faster than specifically targeting the half of your body that your current program is not touching.  I am not sure who said this, but it is one of the most accurate comments I have heard come out of the fitness community:

The only people who think women should not lift heavy weights are women who fear effort and men who fear strong women.
              
           Do not live your life, and especially, do not determine your health by someone else’s misconceptions.  Embrace the challenge of difficult exercises with heavy weight: Power Cleans, Hang Cleans, Front Squats, Back Squats, and Deadlifts.  Get under the bar and get results!
