that squats, deadlifts, power cleans, and probably most of the other "heavy lifting" exercises, other than bench i think, the bar travel should be as close to straight up and down as possible? correct me if i'm wrong. when i did powercleans last night, i had the bar on a 3'x3' rubber mat with the weight resting in the center of each mat. if i focused on keeping that weight directly above it's starting position and _I_ moved under it, the bar ended up on my front delts with the weights hovering directly over the same spot they started on. so, the bar travelled pretty straight. i tried to do this with squats as well and will also do the same for deads tomorrow. your thoughts?
