The Public Library of Science (PLoS ONE) published, "A systematic review of surface electromyography analysis of the bench press movement task." After reviewing 3847 articles and looking at which muscles displayed the greatest activity during a standard flat bench press, they found the pectoralis major and triceps brachii had significantly higher action than the anterior deltoids. Exercise intensity, mental focus, fatigue, velocity, stability all effect electrical activity with the tricep brachii showing the most fluctuation in increases and decreases.
The Pendulum Vertical Chest Press has advantages over the standard barbell bench. When an athlete is seated properly on the Vertical Chest the strength curve does not have a sticking point unlike a flat bench. If seat height is adjusted higher than normal on the Vertical Press there is shoulder relief with the exercise targeting the pectoralis major muscles. This is a tremendous advantage for returning an athlete post injury. Setting the seat lower than normal puts the stress on the anterior deltoid, which can be felt immediately.
The Pendulum Vertical Chest Press is the ultimate upper torso machine that maximizes development and allows for step by step progress through rehabilitation. A terrific way to Get Strong.
