I've done Insanity (a month), p90x completed, and rushfit (GSP's mma conditioning workout) and those 3 are pretty good workouts of course p90x was the one that helped me lose 50lbs, rushfit helped in toning a bit (didn't do cardio so that could be my drawback), but probably gonna start doing insanity because that one is pure cardio...mixed with alternating weight lifting...but yes you're already looking pretty nice in your showcase pics so it'll be a sight to see what 2 months will do for you
