As long as you want to see the best training effect in chest muscle training, we will constantly emphasize this point. When you want to do bench press, the first thing you have to do is to press your shoulders down and use your lower trapezius muscle to prevent the upper trapezius muscle from dominating this action. Why? Because when you involve trapezius muscle, you will push your shoulders up and forward, which will make your shoulders take precedence over your chest muscles and become shoulders to push.

Similarly, when you are doing the flexion and extension of the parallel bars, you make the trapezius muscle shrug again because of the deformation of your weight and posture. You should actively press down, let the chest muscles exert strength and fully contract the muscles.

2. Every contraction should start from the pectoral muscle.

You will find that the toe of deltoid muscle and pectoral muscle will interact. If you don't care, you will miss the chance to get more results every time your muscles contract, because your body will want your shoulders to lead. You should let your chest muscles move forward a little bit and use them to complete the push action as the first line of defense. As long as you take the initiative to hold your chest and let your muscles contract from here, you will feel it. You just need to move forward a little bit to feel it. Because of the contraction of the pectoral muscles, if you continue to push, you will feel different, it will be very different.

Use adduction

Adduction is very important for the complete contraction of the pectoral muscle. When you use adduction to contract the pectoral muscle, it will help you to pursue the complete contraction of the pectoral muscle. Because the function of pectoral muscle is not only to push away from the body, but also to let the arm pass through the body.
