Science based chest exerts should theoretically be much more effective than random chest workouts and pec exercisings since they should be proven.In this video, I’m going to show you how to get a bigger chest employing a technique that has stood the test of time in the rehabilitation field.Proprioceptive Neuromuscular Facilitation( PNF) utilizes the concept of diagonals when it comes to get muscles to work harder and more forcefully.
In order to develop your chest you need to take the muscle through its full scope of motion and offer optimal resistance to the muscle in all regions of the exercise.We know that the pecs will adduct the shoulder the arm across the chest( acting at the shoulder ), internally rotate the shoulder and drive the limb out in front of the body.In its stretched position you would do the opposite.Horizontally abducting the arm and externally rotating the shoulder will put the pecs on a greater stretching and eccentrically position the arm into a ready country to perform the next rep.
Using the concept of PNF diagonals, you can turn your ordinary cable crossovers into something that is much more effective for house a bigger chest.This is due to the fact that you can increase the strength of contraction by doing this and therefore drive more tension into the muscle rep after rep after rep.
If you want to build a big chest you need to adduct against resistance.You simply can’t think that performing adduction at the shoulder without the concentric or eccentric resistance is going to be enough stimulus for growth.It is not the motion at the joint alone, but rather the defied motion that counts.
The falling down to the ground during this exercise allows your limb to be positioned in an elevated abduction.This places a greater stretching on the chest due to the anatomy of the muscle and the angling of the fibers out and up.From this stretched posture, you can drive the arm out in front of your body while contracting the pecs and pushing the limb across the body.Finish off the movement by simultaneously internally rotating your shoulder and you will feel a contraction like never before.
Not merely a chest contraction however, since that can be achieved once again merely by placing your arm in the position of adduction across the chest, but instead in a resisted state.Remember, with cable training the orientation of the cable represents the line of force.If it is parallel to the arm( the area controlled by the pecs in this exercise) then you are driving very little force into that muscle.If perpendicular( as it would be at the peak contraction of a cable crossover) then you are maximizing the work done by the pecs and thus inducing them for maximal growth.
