You just have to be dedicated to it, I got it over the summer and messed around with the workouts, but didn't actually start doing it religiously until the end of August. If you keep up with it you get awesome results. After a month my pack is already coming in, biceps and chest are double the size they were when I started. It's not easy but it is simple, just follow the program, it'll kick your ass. If you want tone it's the way to go.
