content: PSA for Twinks I've noticed so many guys at the gym who have no idea what they're doing.   Today at the gym, there were two twinks who weighed about 140lbs each doing biceps and triceps the entire time I was there. They're wasting their time.  If you want to get bigger focus on heavy compound lifts: squat, bench, deadlift, rows, press, pull ups, dips That's not to say you should never do isolation exercises. They can be good for accesory work. Hopefully this is redundant, you're all big brain boys.
