Elite athletes are the leanest, fittest people on Earth.

Interval training is a scientifically and clinically proven fitness plan based on the training methods used by top athletes. Interval training builds muscle, burns fat and improves the cardiovascular system, and is the most time-efficient workout around. The initial success that comes with new exercise programs usually doesn't last long.
