Why does each workout program use intervals?

Interval training provides the greatest improvement in the shortest amount of time and training, making your workout more efficient. For people looking to lose weight, interval training can help you achieve your goals faster and more efficiently.

Our programs apply intervals that alternate between intense bursts of activity and fixed periods of less-intense activity, or rests, to benefit everyone from beginners to elite athletes. Beginners can use interval training to work their way up to higher intensity exercise for longer periods. Advanced exercisers can use high-intensity intervals to improve speed, power, and performance.
