In many muscle-building principles, everyone will hear a sentence, that is, to extend our peak contraction time, and then let the muscles have a better congestion effect to promote muscle growth. Let's make a small series to talk about a deltoid shoulder training skill and how to prolong our apical contraction time.

How to do the dumbbell side lift? When we do side lifts, Bian Xiao suggested that the included angle of the forearm arm should be as large as possible, so the effect would be better than that of a small included angle, because the longer the distance between our force line and the fulcrum, the greater the torque, and the more obvious the stimulation to the deltoid muscle.

How does this action strengthen our top contraction? Many people are actually used to doing this kind of side lift with a relatively small angle, such as 90 degrees, 120 degrees. Let's take this action as an example. When we reach the top, we hope to extend the contraction time of our top.

Then when putting down, it is suggested to spread your arms when your hands are at 90 degrees, spread your arms flat, and then put them down before doing it. This actually has an extra horizontal abduction on our gyro, which also increases the contraction time of our gyro and strengthens the effect of the contraction time of our gyro.

We can try to do this in the next shoulder training, and we will find that our training intensity has been obviously improved due to the strengthening of the top contraction time.

After we extend the time of apical contraction, we may need to replace a lighter dumbbell to really complete the required number of times. This is an example of extending apex contraction by taking the horizontal lateral lifting of the middle bundle of deltoid muscle as an example.

If you want more strength, you can choose to sit in a sitting position to do this kind of lateral arm abduction reduction action, which will better help us exercise. We have a lot of fitness exercises that need to apply the peak contraction principle. After mastering the principle of peak contraction, we can apply what we have learned.

There are many functions and principles that are actually related. Only by mastering the real principles can we exercise better. When we are doing a training, the so-called slow reduction is also to maintain the tension of the target muscle we want to exercise.

We can think the other way around. If we use gravity to descend immediately after completing the acrosome movement, we will lose the purpose of exercise and the tension of the target muscles, so that long-term training will not achieve good results in the end.

If all training is cut corners like this, we might as well not choose fitness in the first place. It is impossible to cut corners on things like fitness, otherwise it will only waste our time and won't change anything. It is out of the question.

In order to better yourself, treat every exercise well from now on and strictly demand yourself to complete the goal. Thank you for reading. Welcome to forward. Like it.
