The exercise can be enhanced by holding weights to the chest. Lighter weights may be used to begin with to prevent straining the back muscles with over-exertion. The weight may be held in a lower position by a beginner, then gradually held higher, to feel more resistance. [2] Using a back extension bench (hyperextension bench)
Muscles which flex the elbow joint such as the biceps brachii muscle, brachialis muscles and brachioradialis muscle are active to improve leverage. [1] As the biceps originate on the scapula unlike the other two which originate on the humerus, the biceps are inclined to serve a role as a dynamic stabilizer, much as the hamstrings would during a ...
Extension of the hip or shoulder moves the arm or leg backward. [11] Even for other upper extremity joints – elbow and wrist, backward movement results in extension. The knee, ankle, and wrist are exceptions, where the distal end has to move in the anterior direction for it to be called extension. [13] [page needed]
