The major muscles help in actions like flexion, extension, abduction, adduction, elevation, inversion and rotation. Triceps Brachii: It is a muscle on the back of upper limb that extends the arm at the shoulder and forearm at the elbow. It originates from infraglenoid tubercle of the scapula and its insertion is in olecranon process of the ulna. Push-ups, bench press, and dips exercise this muscle. Biceps Brachii: It is a muscle on the upper arm that flexes elbow and supinates forearm. Its short head originates from the coracoid process of the scapula and long head from supraglenoid tubercle. Its insertion is in tuberosity of radius and bicipital aponeurosis. Dumbbell biceps curl is its best exercise. Deltoid: This muscle forms the rounded contour of shoulder and helps in shoulder abduction, flexion, and extension. It originates from an anterior lateral third of clavicle and its insertion is in deltoid tuberosity of the humerus. Weights training for deltoid raise make it strong.
