Whats up, I was wondering what a good weight lifting routine is to get every muscle/area and get a good workout without over-doing it. My friend has this thing where he does every machine in the gym, and them dumbells. It seemed kind of stupid though sense like 3 of the machines show they target biceps and shoulder. I understand if one works biceps as a secondary and then doing a machine that does them primarily. Does it really help to do so much or should you do one machine for each muscle in 3 sets, then mabye the dumbells?
