Elbow Extensors
Triceps Brachii, Anconeus

Shoulder Flexors
Anterior Deltoid, Pectoralis Major, Coracobrachialis, Biceps Brachii

Scapular Depressors
Lower Trapezius, Serratus Anterior, Latissimus Dorsi, Pectoralis Minor
Keep the shoulders down away from the ears throughout the entire exercise.

Other Muscles at Play
Spinal stabilizers create trunk, ribcage and lumbo-pelvic stabilization in the kneeling position and keep the back from arching.
Hip extensors work with the spinal stabilizers to create lumbo-pelvic stabilization.
Scapular adductors (retractors) keep the shoulder blades drawn together especially as the bar presses down to keep the shoulders from rounding forward.
Objectives
Opens the front of the chest and shoulder.
Strengthens the chest and the anterior upper arm.
Emphasizes scapular depression to properly target the chest muscles while pressing the bar.
Develops deep core integration to support the back and prevent unwanted spinal extension.
Lubricates the elbow and shoulder joints through the circular pattern.
Focus on breathing to synchronize the movement.
