The<unk><unk>  assists in depression of the arm with the teres major and pectoralis major. It adducts, extends, and internally rotates the shoulder. When the arms are in a fixed overhead position, the<unk><unk>  pulls the trunk upward and forward. It has a synergistic role in extension (posterior fibers) and lateral flexion (anterior fibers) of the lumbar spine, and assists as a muscle of both forced expiration (anterior fibers) and an accessory muscle of inspiration (posterior fibers). Most<unk><unk>  exercises concurrently recruit the teres major, posterior fibres of the deltoid, long head of the triceps brachii, among numerous other stabilizing muscles. Compound exercises for the 'lats' typically involve elbow flexion and tend to recruit the biceps brachii, brachialis, and brachioradialis for this function. Depending on the line of pull, the trapezius muscles can be recruited as well; horizontal pulling motions such as rows recruit both<unk><unk>  and trapezius heavily. Training The power/size/strength of this muscle can be trained with a variety of different exercises. Some of these include: * Vertical pulling movements such as pull-downs and pull-ups (including chin-ups) * Horizontal pulling movements such as bent-over row, T-bar row and other rowing exercises * Shoulder extension movements with straight arms such as straight-arm lat pulldowns and Pull-overs * Deadlift
