Chin-Up

The Chin-Up primarily works the Biceps Brachii (Long Head), Biceps Brachii (Short Head), Latissimus Dorsi, with secondary activation of the Brachialis, Brachioradialis, Levator Scapulae, Pectoralis Major (Sternal), Pectoralis Minor, Posterior Deltoid, Rhomboids, Teres Major, Trapezius (Lower), Trapezius (Middle) and stabilizer support from the Biceps Brachii (Long Head), Rectus Abdominis, Rhomboids, Transverse Abdominis, Triceps (Long Head). It is a bodyweight compound exercise at intermediate difficulty.

The Chin-Up is a intermediate compound exercise requiring no equipment, following a vertical pull movement pattern. It primarily targets the Biceps Brachii (Long Head), Biceps Brachii (Short Head), Latissimus Dorsi, with secondary engagement of the Brachialis, Brachioradialis, Levator Scapulae, Pectoralis Major (Sternal), Pectoralis Minor, Posterior Deltoid, Rhomboids, Teres Major, Trapezius (Lower), Trapezius (Middle). This is a bilateral pulling movement, engaging both sides of the body simultaneously.

Primary Secondary Stabilizer

The Biceps Brachii (Long Head), Biceps Brachii (Short Head), and Latissimus Dorsi are the primary movers, collectively driving the movement and absorbing the greatest share of the load. The Brachialis, Brachioradialis, Levator Scapulae, Pectoralis Major (Sternal), Pectoralis Minor, Posterior Deltoid, Rhomboids, Teres Major, Trapezius (Lower), and Trapezius (Middle) act as secondary movers, assisting the primary muscles and contributing meaningfully to the overall output. The Biceps Brachii (Long Head), Rectus Abdominis, Rhomboids, and 2 other muscles act as stabilizers, maintaining joint position and postural alignment throughout the movement.
