Watch most people do a bent over row, whether it’s a dumbbell or barbell version, and what you’ll usually see as the set goes on is that it turns into less and less of a bent over row. By the end of the set you’ll see some people in an almost upright position. The last rep hardly looks like the first rep.
To combat this change in body position, I picked up this head supported version from strength coach Eric Cressey. Focusing on keeping your forehead in contact with the bench the duration of the set will keep you in check and keep you from rising up. Take a look.
