30 Strange Fitness Facts & Myths Debunked

Posted Apr 16 2013 7:27pm
  1. Cholesterol is not a good indicator of future hearth disease.  A large waist size (over 40 inches for men and 35 for women) is a much better indicator of future cardiovascular disease risk then cholesterol levels.  
  2. Pound for pound your tongue is the strongest muscle in your body and your glutes (butt muscles) are the strongest in absolute terms.  
  3. There are 10 bacteria cells in your body for every 1 human cell you have.  Meaning you are more bacteria then human! Furthermore, most of this bacteria in and on your body is not yet classified by science.  Click here for more. 
  4. "It takes on average 17 muscles to smile and 43 to frown" is not rooted in science and is untrue. Actually, it takes about the same amount of muscles to frown as it does to smile.   
  5. Every day an adult body produces 300 billion new cells. To make those cells your body uses the food you take in...you are what you eat so think about what you put into your body.  
  6. Most of us are about a half inch taller in the morning.  Click here for why. 
  7. Your body uses almost half of its 650 muscles to balance you out while standing still. 
  8. Lean muscles do all their growing on your rest days.  Without proper recovery times in between workouts (about 48 hours) you will negate your efforts and possibly lose ground by over training.  Fix your sleep. This is the most vital part of your rest, your body is at very high recovery when you are having good sleep.
  9. Most of our human cells (not all) will be completely replaced every 10 years.  Different tissues in the body replace cells at different rates, and some tissues never replace cells.  
  10. The "cracking" or "popping" sound you hear (crepitus) when moving your appendages is gas being released....not bone rubbing on bone. 
  11. Muscle fibers are thinner than human hair yet each can support 1000x its own weight. 
  12. During the first 2 months as an embryo we start to develop a tail and by the 9th week it disappears, leaving the coccyx (the last segment of the backbone).
  13. No other mammal has as such a large a proportion of fat around the buttocks as humans...no one seems to know why this is true, although theories are abound. 
  14. The penis contains no muscle tissue. 
  15. An infant's foot has about 20x the toe grasping capacity as a shoe-wearing adult.  However, in shoeless societies adults retain this pre-hensile ability. Click here for more.  
  16. Your liver and skeletal muscles store about 12-24 hours supply of glycogen (sugar)....but once they are filled up, any extra carbs eaten will be converted to fat for long term-storage.  Daily exercise prevents your muscles and liver from being filled up.  
  17. Science is not sure why we yawn or sleep.  However, most humans will die after 11 days without sleep. 
  18. Tight calves can give you headaches by tightening your fascia (tissue covering your muscles) which run in continous bands from your heels all the way up to the back of your skull.  
  19. Static stretching before an exercise or event will "turn-off" the muscles you are stretching and make it less active during movement.  In fact, runners who stretch before running burn 5 percent fewer calories than runners who don't stretch.
  20. Hanging in a pullup position does not stretch most of your muscles (it contracts them) but will temporarily make you up to 1/2 inch taller.   Click here for more.  
  21. Exercise works just as good (and in some cases better) at alleviating depression as anti-depression medication. 
  22. People who want to quit smoking are twice as likely to succeed in quitting if they lift weights than if they don't lift weights.
  23. There is a common myth that we use only 10% of our brains yet fMRI's and PET scans show we use 100%! 
  24. Exercise has been show to increase brain volume and  grows new brain cells. The latest neuroscience suggests exercise does more to bolster thinking than thinking does! 
  25. Snot from sneezes do not travel 100mph...The science based TV show Myth Busters , clocked snot at a slow 35-39 mph. 
  26. Swimming workouts tend to make people hungrier then similar intensity running or biking workouts. 
  27. Eating eggs does not increase your cholesterol level and in fact may pro long your life.  Click here for more.
