B Fold, my buddy and I had a similar experience the other day. He and are are the two biggest, and strongest guys in our yuppie gym, no great feat. This older guy, mid 40's at least, with a gut and pipe cleaner arms, comes up and tell us that we're doing the preacher curls wrong. How so, we ask. He then tells us that you are not supposed to use a full range of motion and go all the way to the bottom, it puts you at risk for an injury. He then brags that he used to use 95lb dumbells for curls on the preacher, and one day he tried to go all the way down and tore a tendon. Gee, I can't figure out why?
If I wanna look like him, maybe I'll try his advice. But until then, I think I'll continue to do it my way.
