sigh, when will this endless need for clarification end? I meant 100% concentration in my rest between sets. minimise rest, save more time. AND I'm not saying I use my entire rest time to look. not even close.
having said that, i saw a girl doing tricep pulldowns with the v-bar attachment on the cables with flared elbows, thought to myself "oh that's bad form, should say something" but then i realised that it would probably be taken the wrong way. not to mention I'm no pro myself, but I do know that the elbows are to stay by the side.
