The leg extension machine was created by American fitness guru Jack LaLanne in the 1950s. [3] The first prototype is recognized to have been made under Gustav Zander, but labeled the machine as a form of “mechanotherapy” along with other machines that extended the knee and ankle. [3] The machine was made to target the quadriceps.
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).
In anatomy, extension is a movement of a joint that increases the angle between two bones or body surfaces at a joint. Extension usually results in straightening of the bones or body surfaces involved. For example, extension is produced by extending the flexed (bent) elbow. Straightening of the arm would require extension at the elbow joint.
Also known as a calf slicer or leg slicer, the calf crusher is a Compression lock that involves pressing the calf and/or thigh muscle into one of the bones in the leg. Similarly to the biceps slicer, a calf crusher can be applied by inserting an arm or leg in the backside of the knee and flexing the opponent's leg to apply pressure to the ...

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.

The fascial compartments of the leg are the four fascial compartments that separate and contain the muscles of the lower leg (from the knee to the ankle). The compartments are divided by septa formed from the fascia.
