I've completed the p90x doubles program. Definitely a good workout program. I play basketball at a decent level, so obviously its not ideal for a specific sport, but in terms of getting fit, it definitely works. I still use 2 of the lifts per week in my sports specific workouts as the arms and chest / back related excersizes are amazing IMO.
The plyo part isn't really plyo, its more intense cardio, real plyo is more about less reps and maximum explosiveness in terms of sports training, but I'm getting a bit sidetracked.
Shit works. Period.
