It may seem to you that it is harder to build the inner chest as opposed to the outer chest. There are three basic reasons why:
- Not having proper equipment
- Not using proper form and technique
- Not understanding arc movements.
The truth is this: In order to most effectively build the inner chest, you must remember that it’s not about the extension of the arms, but it’s about the rotation of the shoulder. For you to acquire a peak contraction in the chest, it requires the shoulder to completely rotate forward as you are contracting with resistance. Unfortunately, because of the inherent constraints of most chest exercises, building a great chest becomes more difficult.
Quite frankly, most exercise equipment is inadequate when it comes to maximizing the development of the chest. In fact, I had to design my own piece of exercise equipment – the Iron Chest Master – in order to find an adequate remedy for this problem. Prior to understanding arc movements, my chest was the weakest part of my physique, and I had to discover a solution through work, research, testing and study so that I could balance my entire body.
Ultimately, at the conclusion of this process, what I discovered was simply this: Every muscle group in the body is made in an arc formation, and in order to build and maximize the muscle size and shape we must stay within that arc that the muscle was created in. This not only builds the muscle, but it protects the joint.
Let us use the bird as an example. I studied the anatomy and the movement of a bird in flight. The largest and leanest muscle group on a bird is the chest. I also noticed that the structure of a bird’s upper body is similar to a human when it comes to the chest and the shoulder joint. The bird flies using an arc, which develops the chest as it protects the joint. As the bird flies, he receives resistance from gravity, but he also produces lateral resistance as he pushes against the air. This maximizes the development of his chest. I duplicated this movement in the Iron Chest Master.
The Iron Chest Master allows its user to move in the same arc formation as a bird in flight, mimicking the arc movement and developing the chest in the same manner using the downward pressure of gravity during the pushup phase, along with lateral resistance from resistance bands, creating a peak contraction and complete development of the inner chest.
Let me explain some of the limitations of a few of the most popular chest builders.
