WHAT IS HIGH INTENSITY INTERVAL TRAINING?

High Intensity Interval Training (HIIT) involves brief, high-intensity movement followed by brief periods of rest. HIIT workouts can be more effective than 30 or 60-minute workouts. Power 20 is a form of high intensity interval training.

WHAT ARE PLYOMETRICS?

All the exercises in Power 20 are “plyometric” exercises. Plyometrics are designed to produce fast and powerful movements that improve your ability to do useful, real-life tasks, like running in short bursts, lifting things, climbing stairs, and avoiding falls.
