its great for size. theres a lot of bodybuilders out there who got their start with powerlifting and continue to implement powerlifting into their training program.
usualy when people come to me saying they want big arms, ripped abs, etc.., i put them on a DC style training program. but if they just want mass and dont care for what i call "pretty/beach muscle" then i put them on more of power program.
so what are you're goals? do you want mass and willing to work on pretty muscle later, or do you want pretty mucle now?
