Biceps Brachii
The strongest flexor of the elbow joint (long and short heads); flexes the elbow, supinates the forearm, and weakly flexes the shoulder; a 2-joint muscle (ROM 135°).Brachialis
The only pure flexor of the elbow joint; pulls on the ulna, which does not rotate.Brachioradialis
A forearm flexor that flexes the elbow and both supinates and pronates the forearm.Intensity
The amount of weight (resistance) lifted — also shaped by speed, reps, sets, rest interval, and workout duration.Momentum as an Injury Risk
Momentum-assisted lifting increases stress on joint structures and injury potential while decreasing the demand on the target muscles.
