trying to apply some physics to the 4 major power lifts. the key area I wish to analyse is bar path in a squat and deadlift. the work done against gravity is independent of path? a lifter can either have a straight as possible body path and deviate the bar path or the lifter can alter his body path and have a straight lift of the bar. my position is bend your body around the bar to give the straightest bar path possible, preferably a vertical bar path. how could I prove this is the most efficient lift? talking maximum possible lifts.
