Stabilizers

Lat Pulldown: Targeted Muscle Groups

Agonists

• Latissimus Dorsi (largest back muscle)
• Teres Major (muscle near the bottom portion of the shoulder blade)

Synergists

• Posterior Deltoid (back of the shoulder muscle)
• Trapezius- upper, middle, lower) (a large trapezoid shaped muscle of the back)
• Rhomboids (muscle that connects to the shoulder blades and spine)
• Levator Scapulae (located near the side and back of the neck)
• Biceps Brachii (front of upper arm muscle)
• Brachialis /Brachioradialis (forearm muscles)

Stabilizers
