I started with P90X in 2010. I did P90X, Insanity, P90x2 and Body Beast, in that order. I did each program twice, except for Insanity. I really did not get good results from Insanity and clearly lost ground there, nothing against the program and I'm sure it works for others, but not so much for me.
I am 51 years old. I am 6' 4" tall. Before P90x I was about 215 lbs. After P90x2 I was around 200 lbs. Now after Body Beast, I weigh around 225. What do you think???
Pictures are in the order I did the programs:
