Athletes who struggle with explosively accelerating up the thighs will benefit more from block work as the bar starts at a dead stop. Inversely, because the bar is on block it eliminates the need for the isometric holding of the weight from certain positions before performing the lift. Newer athletes who have not developed correct positioning yet will benefit more from this type of work.
Athletes who struggle with isometric strength and eccentric strength will benefit greatly from hang work. Hang work will also give the athlete better awareness of where their body is in space. This helps create the connection between the athlete and the bar that will help the athlete be aware of their center of gravity. Also, if you are looking to create superior posterior chain strength, lowering the weight from the hang to the desired position work is the way to go.
