3rd Round of P90X

So since 2008 I've done two rounds of P90X with different goals both times, the first one to lose weight and I lost 30 lbs in 90 days. The second round I gained muscle. Now I started a third round on December 28th of last year, this is my third week and I'm planning on losing body fat and get physically ready to start P90X:2 after I finish this round and start putting on some muscle mass.

Anyone starting or currently doing P90X too?
