I never used to do them, but had a little extra time yesterday so said I'd try something new. Overhand bent over with the barbell felt horrible. DId a little research. Apparently they hit the lats a lot better with an underhand grip. I actually liked doing them from sumo stance and grip also. Then I see, them rows - t-bar rows - so figure they might be a good fit. In terms of development though - are they more of an accessory exercise?
