My younger brother who is 17 has been working out hardcore for about 4 years now. He currently weights in at 170lb at 12%bf and 6'. His stats consist of 385 bench. 510 dead lift, and not sure on his squat. He knows i dabble in the use of as. and is wanting to get into it himself. but im not sure what to tell him. he doesnt look like he weighs in at 170lb, but more like 190lb. any advice?
