if i have a whole lot of energy i may do a deadlift movement with dumbells(100+lbs ea) but i have to use straps cause i like to start with real deads. and by the time im done with those, i cant hold a dumbell anymore.
almost seems more of an aerobic deadlift, i dont pause. dont get that deep muscle burn, but it sure as hell exhaust the back. and im breathing like i ran a mile.
