P90X2 - Plyocide.

Death by plyometrics? Not exactly, but that's how you might feel the first time you attempt it. Plyocide combines traditional explosive movements with mind and coordination drills to increase not only your speed and endurance, but your entire mind/body connection. Don't do this more than once per week. Combine explosive movements with mind and body coordination, and watch your performance go through the roof.
