i started it and did it for about 2 months. then work got really busy and i was preparing for my vacation and just didnt have time, so i stopped for like 2-3 weeks. im gonna start back up though.
when i started i was about 165 (im 6'0") and kinda flabby, not overly overweight, ive always been pretty thin my whole life. i started slow, as i couldnt physically finish the entire videos. do what he says, take breaks, and do what you can. dont feel bad about quitting early, or doing girl pushups, or cheating on pull ups with a chair. after the 2 months of working out (not super strict, missing a day here or there) i was up to 170 with a noticable loss of fat and gain in muscle mass. i didnt really follow the diet guide, just tried to eat more protein, and more fruits and veggies, and had protein shakes after workouts.
like i said, im about to start back up, and once you get a few weeks in, the workouts are hard, but not impossible and youll actually feel good about the workout.
just my take so far.
