Can an 12 year old do p90x?

Answer 1

of course it is you just have to have athletic prowess before you begin lets say you do track or football or swimming etc.) that is like a warmup for p90x so i guess anyone at any age could do it

With the greatest respect; this guy knows nothing. You should be over 14 before you go near it; if you want to do an intense workout; go look up Insanity. It's made by Beachbody, and only uses your own bodyweight; it'll be much better for you than P90x. And this is from someone who's done both.
