Hey FitLAFoodie and everyone else
I did Insanity, Asylum 1, Asylum 2. I am starting my second round of Insanity! I have a thread
HERE if you want to check it out
I definitely saw muscle gain through these programs, HOWEVER, I started out with nothing. I have never really done any weight lifting before. Asylum 1 and 2 both have more weight lifting and I definitely saw more muscle gain during those.
