P90x Plyometric Workout

http://www.beachbody.com/

P90X plyometrics is one of the toughest non cycling interval workouts you can do in your living room. It is fifty minutes distributed between your Zone 4 (lactate threshold), Zone 5 (VO2 max) and an excursion into your Zone 6 (Anaerobic Capacity) with about four thirty second - partial recovery/rest periods interspersed. Five minutes warm up and five minutes cool down. The way this workout is structured with only partial recovery would lend itself to more of a speed endurance workout, rather than a workout designed to build pure speed strength (power).
