With these exercises, the foot is kept on the ground while movement and resistance take place in the joints and muscles above. These types of exercises are important because they are akin to the activities we do every day. For example, a partial squat exercise is the same action as lowering yourself onto a chair or couch. A leg press is a lot like the action of going up a stair or step. These exercises add strength and stability around the muscles and joints of the hip and leg.
