Here's why you should sprint

In class I have you guys sprint.  We ran 12 yesterday.  There's a reason I have you do only one lap around the track.  Sprinting works.  It gives you incredible results.  So, when I say sprint one lap.....you better sprint!

Here's some facts.

1 -Evidence shows that short, high intensity sprint workouts improve aerobic capacity and endurance in about half the time of traditional endurance exercise.

2- One study found that just six sessions of four to seven all-out thirty-second sprints (with four minutes of recovery between sprints) could be as effective at improving cardiovascular fitness as an hour of daily moderate-level aerobic exercise. (WHAT! That's AWESOME!)


3- If you do a harder, higher intensity activity, like sprinting on a track, or a bike, you'll burn an overall greater amount of calories in the same period of time. (More calories for the same about of time?  AWESOME! I'll never walk again)

4- For decades, scientists have known that short-duration anaerobic exercise improves athletic performance, and that the release of human growth hormone (HGH), testosterone and other bone-building, body-enhancing hormones are directly related to the intensity not the duration of exercise. (1) When charged with these anabolic hormones, our bodies build more muscle mass, which dramatically improves weight loss, resulting in slimmer, more-toned physique. Anabolic hormones are also known to enhance skin and hair, improve sleeping habits, strengthen immune response and improve sexual performance. ( Better Sex - whatever, but better sleep!  Heck yeah, I'm in!)




So, when I say sprint, remember this and sprint even harder!
