The pectoralis major is one of the powerful muscles of the upper body. It is a fan-shaped muscle of the shoulder joint, which can be subdivided into three parts with two distinct muscular heads-the clavicular head and the sternocostal head. The pectoralis major attaches to the upper arm or better said, inserts at the crest of the greater tubercle of the humerus.
The sternal head of the pectoralis major is most active when doing a flat back bench press and remains the most active part of the chest complex up to roughly a 30 degree incline.The anterior deltoid begins to become more engaged as the incline angle increases. To train the clavicular head of the pectoralis major the optimal angle is an incline of somewhere between 45 degree and 60 degrees. As the incline bench angle becomes higher than 60 degrees the abduction angle allows the deltoids to be increasingly effective and contribute more to the movement.
The Pendulum Shoulder/Incline can be changed quickly into three different distinct machines that allows the athlete to isolate the specific regions of the pectoralis major and target the anterior and middle heads of the deltoid.
The Anterior and Middle Deltoid setting on the Pendulum Shoulder/Incline
The Clavicular Head of the Pectoralis Major setting on the Pendulum Shoulder/Incline
The Sternal Head of the Pectoralis Major setting on the Pendulum Shoulder/Incline
Using the Pendulum Shoulder/Incline is a great way to Get Strong!
