A lot more effective than standard cardio, Interval X Plus propels your heart rate up and down with 3 speeds: recovery, medium, and full-out, creating the most dramatic change in the shortest period of time.

This advanced-level Kenpo, with new moves, will shred the most stubborn layer of fat with an all-out self-defense workout that builds stamina, balance, and agility.

This monster upper-body workout will defy the plateau phenomenon by blasting all the muscles from the hips on up: chest, back, biceps, triceps, and shoulders, in a complete synergistic P90X way. After this one, you won't be able to pick up a ping pong paddle for a couple hours.

By adding new synergistic moves, your muscles get pumped, then recuperate in stages until you've got nothing left. An unprecedented total-body phenomenon.

This advanced new ab/core workout adds 4 different positions (hanging, sitting, standing, and plank positions) to intensify your ab work and shred your midsection even faster. Is a ten-pack even possible? You'll find out.
