I just got the whole P90X DVDS and it has a Plyometric training CD in it... i wanted to know if every one knew what that was? what it improves? what it does to your muscle? does it tone?
my brother and his wife are p90x success stories and have been featured on the infomercial. it works they both look great! and its awesome! plyometrics includes a lot of jumping and twisting wear shoes protect those ankles. you will be smoking when u get done with p90x!
