Rotary arm wrappers: In this system, the load remains still while a rotating arm turns around it ...
Bridging exercises are done with a flexed knee to lessen the stretch on the hamstring (a knee flexor) and focus the hip extension work on the gluteus maximus. In that same respect, the reduced knee flexion makes plantar flexion work comparable to a seated calf raise, due to the lessened stretch on the gastrocnemius (like the hamstring, also a knee flexor).

The rotator cuff compresses the glenohumeral joint during abduction of the arm, an action known as concavity compression, in order to allow the large deltoid muscle to further elevate the arm. In other words, without the rotator cuff, the humeral head would ride up partially out of the glenoid fossa, lessening the efficiency of the deltoid muscle.
