Five Fitness Numbers You Need to Know

Scale bodyweight, bench press maximum, some “girl name” and a time are all fitness numbers your hear in the gym.  If you are interested in optimal performance and health, I have the fitness numbers we all need to know.  Focusing on these numbers will keep you active and independent for a lifetime.

1) WAIST CIRCUMFERENCE

The location of bodyfat is far more important than the amount of bodyfat.  Visceral fat, the kind stored in and around the belly, is the hormonal driver of metabolic syndrome; the precursor to diabetes, elevated blood lipids, high blood pressure, and coronary artery disease.  To optimize health, you need to monitor the diameter of your waistline.  The number you want to know is your waist to height ratio.  You want your waist to be less than half your height.  If your waist size is greater than one half your height, then reducing your waist diameter should be the primary goal of your fitness program.

2) SLEEP TIME

Sleep is the ultimate exercise recovery activity.  One or two nights of sleep deprivation has been shown to reduce gym performance by 25% – 40%.  We need seven to eight hours of restful sleep, each and every night.  The most important benefits of exercise are neural and hormonal.  Sleep reboots our neural software and replenishes the hormonal system.  Medications, respiratory problems, sleep apnea, and obesity all can interfere with sleep patterns.  Fixing these health issues and developing better sleep habits produces magical progress in the gym.  Read the book, Sleep Smarter by Shawn Stevenson.

3) FUNCTIONAL MOVEMENT SCREEN SCORE

The Functional Movement Screen (FMS), developed by Physical Therapist Gray Cook and Athletic Trainer Lee Burton, is a seven-step dynamic movement based test that has become a standard of practice in physical therapy and sports performance centers.  The FMS helps prevent injuries before they occur by identifying risk factors.  Movement indicates how a body works and lets us know how the brain is controlling the body and how the joints and muscles communicate.  Just like a good medical work up, the FMS permits the trainer / therapist to make the proper decision about the clients’ most urgent needs and avoid gym activities that are detrimental.

4) GRIP STRENGTH

Recent research has demonstrated that knowing your grip strength is as important as knowing your blood pressure.  The PURE research of 140 thousand individuals revealed that a drop in grip strength is a strong predictor of mortality from all causes.  We will all face health battles and the stronger body wins while a weaker body loses.

5) NUMBER OF TRAINING SESSIONS PER YEAR

Exercise is ineffective absent consistency.  Even a haphazard program of exercise is beneficial if you perform it on a consistent basis.  The experts say a good goal is 150 training sessions per year.  That is three times a week for 50 of the 52 weeks in a year.  Link together several years of the consistency habit and amazing changes happen.  Most people overestimate the value of a month’s worth of exercise and greatly underestimate the value of a year’s worth of exercise.
