In strength-training terms, a synergist muscle helps you accomplish the movement. The antagonist of the pectoral muscles is the brachiocephalicus muscle which pulls the forelimb cranially. To recruit the brachialis muscle, patients were in-structed to contract isometrically the muscle that the donor nerve originally innervated (pectoralis major, latissimus dorsi, triceps, or intercostal muscles) in various degrees of elbow flexion to increase brachialis muscle.

Although typing and mousing tasks were different (being bilateral and unilateral tasks), the results were mostly consistent across the tasks. Unless you’re naturally gifted, it’s very difficult to recruit the brachialis, in part because of highly variable levels of neuronal innervation among individuals.

Two of the muscles bend the elbow joint (M biceps brachii, M brachialis), while the third muscle (M coracobrachialis) brings the arm towards the body (adduction). Because this exercise helps to recruit the brachialis muscle more than basic alternating curls, it will help with balance and development between the biceps. Lift: Pull the weights to the top of their range of motion. Tendons of forearm muscles typically are surrounded by tendon (synovial) sheaths and held adjacent to the skeletal elements by strong fascial structures.
