A pull-up may be performed with overhand (pronated), underhand (supinated)—sometimes referred to as a chin-up—neutral, or rotating hand position. Pull-ups are used by some organizations as a component of fitness tests, and as a conditioning activity for some sports.
For this test, Marines choose to either perform pull-ups or push-ups. However, the maximum score is only attainable if pull-ups are chosen. The pull-ups may be done with either an overhand (pronated) grip or an underhand (supinated) "chin-up" grip. Changes in grip are allowed as long as the feet do not touch the ground and only the hands come ...
Pronation at the forearm is a rotational movement where the hand and upper arm are turned so the thumbs point towards the body. When the forearm and hand are supinated, the thumbs point away from the body. Pronation of the foot is turning of the sole outwards, so that weight is borne on the medial part of the foot. [33]
Cable pull-down exercise to the front with a medium-width overhand (pronated) grip. The pull-down exercise is a strength training exercise designed to develop the latissimus dorsi muscle. It performs the functions of downward rotation and depression of the scapulae combined with adduction and extension of the shoulder joint.
Exercises that strengthen the back muscles include rows, pull-ups, and shoulder blade squeezes. Exercises like doorway stretches for the chest can help stretch out tension that contributes to rounded shoulders. Synergistically implementing muscle strengthening and stretching can effectively prevent the development of rounded shoulders. [47] [48]
Common lifts for arm wrestling include bicep curls, hammer curls, wrist curls, rows, pull-ups, and other exercises which develop overall pulling strength and greater pressures against the opponent. Pushing exercises are generally secondary, except in certain cases where they strengthen techniques and movements such as the press ( bench press ...
During a snatch or clean, the lifter can exert forces up to 2-3 times the weight of the loaded barbell at rest, and the hook grip allows an athlete to maintain a grip on the bar during the phase of highest bar acceleration, the second pull. The hook grip does this by preventing the bar from rolling in the hands, whereas the bar would have a ...
The biceps is a particularly powerful supinator of the forearm due to the distal attachment of the muscle at the radial tuberosity, on the opposite side of the bone from the supinator muscle. When flexed, the biceps effectively pulls the radius back into its neutral supinated position in concert with the supinator muscle. [14]: 346–347
