Neither word is new, but it is easy to be ignored. It's weird. The more you practice, the more you will feel that they are so important. Not only to avoid injury, but also to improve the efficiency of the action.

Let me talk about flexibility first. Compared with ligaments and fascia, the flexibility and stability of joints here are more important. Take weightlifting as an example, from wrist, elbow, shoulder and thoracic vertebra to hip, knee and ankle, the activity expansibility of every place is very important. Maybe you can't see much when two people lift the empty pole at the same time, but as long as you put the weight on it, the difference will be clear at a glance. Whether the movement can be completed, to what extent, and even whether it will be injured are all related to the flexibility of the joints.

Sometimes even if the strength is enough and the joints are limited, the action can't be done. Very uncomfortable.

However, we can't be tough on flexibility. Generally speaking, girls have an advantage over boys. People are born different, so are athletes and athletes. For example, not everyone in the team dared to come to Yin Da's shoulder-opening gesture:

This degree of joint flexibility is a gift. Don't try to be flexible, it's unnecessary, and you may get hurt.

Why did you drive so far back? Look at the picture again,

When lifting the barbell, the actual position is not directly above the head.

Usually watching weightlifting competitions, I feel that athletes lift the bars from the front, but they are not. Viewed from the side, the actual position of supporting barbell is almost behind the head, which is just above the middle bundle of trapezius muscle and scapula professionally. If you want to feel something, you can try to do a barbell squat, right above the bell lifting position, which is where you grab the clean and jerk lock shoulder.

On the other hand, in the warm-up activation before each training, it is quite appropriate to do some actions aimed at joint flexibility, and then start again after the whole exercise is activated. Don't worry. There are also wrist pads, knee pads, belts, and muscle patches before loading. These must be put on, the joints are stable, and the movements are in place, so as to release strength and link the body.
