I used to lift with a guy who is currently an orthopedic surgeon resident. We were talking training, and he brought up his other residents. They hit the gym at least five times a week. Anyways he brings up their shotty form on dumbbell curls. In his view, too much shrugging of the shoulders and press with the legs.
I’ve thought that strict form and “cheating” form both have their place. But If I was just training to get big and strong and could only do one, I would always choose the “cheating” form. Yes you are incorporating other muscles, but you are maximizing the muscle fibers used because of the increased weight.
What do you guys think?
(Just an aside, it always cracks me up when a typical gym train tells someone to have strict form and then places them on a boso ball. The damn point of a boso ball is to activate other muscles while you are training the “target” muscle. Also, you get more core activation by moving a big weight unilaterally (e.g., single arm dumbbell curl) while not sacrificing load.)
