In high school, (and even these days in the gym), I have seen people with pretty impressive biceps. I generally ask them what has worked for them, and what hasn't, to help formulate my own program, and the responses have always been encouraging, and helpful, but pretty much everyone (in person) recommends that I do concentration curls, and other types of Iso. exercises, but they don't know they are Iso's. I read 0311's thread on The Death of Bodybuilding, and it makes perfect sense. I wonder though: how have these other people built up their arms using senseless iso. lifts? Roids?
