My gym only has 20's and 15's..... we didnt even get told we were getting 15's. I once deadlifted with 5kg less on one side of the bar, it hurt my back.... goddamn Fitness first!!!
but still.... the second one side of the dl left the ground and the other didnt wouldnt you stop??
pro tip #1: when the bar lifts awkward, stop and see whats wrong, usually leads to discovers of misload from training partner trying to sabotageIt lifted awkward and instead if dropping the lift i tried to correct it. I have since learnt otherwise.....
