What is joint locking? Why should joint locking not during training?

We all know that all our exercises must be completed through joints. In this way, joints are more likely to wear and injury, especially when conducting high-intensity training. Therefore, we need to learn the basic awareness of protecting joints and do the right thing to complete the training.

　　Many of our fitness friends often hear this sentence during training: "Don't lock the joints when doing exercises." (51 Muscle Anatomy Video Tutorial)

　Many people can't help but wonder: What is joint locking? Why do you say that? Maybe you know a little, but maybe you don't know much! We Let’s look at it.

First of all, joint locking refers to the movement of the joint to the maximum position during joint movement. It can also be said that the joint is completely straightened and fixed.

For example, if you are in a semi-squat state, the knee joint is not locked. At this time, your force is mainly borne by the continuous contraction of the muscles. In this way, you can effectively exercise the muscles when doing weight-bearing squats;

But joint locking is like standing with legs completely straightened. At this time, the strength is basically transmitted vertically from the bones and tendons, which is equivalent to your bones supporting the weight of the barbell like a pillar, and the joints It is the connection between the bone column! The leg muscles almost don’t need to actively exert force, just maintaining this state can keep you standing. The pressure is all on the joints. (51 muscle anatomy video tutorial)

　　Relatively speaking, the locked state cannot exercise muscles at all, and the strength is concentrated on the joint ligaments, which is very easy to get injured (it is almost certain that it will wear and tear in a long time).

　　So, we hear the prompt "Don’t lock the joints when doing exercises". This is protecting our joints.

　　There are also similar to squats, bench presses, and shoulders. Pushing and other movements that straighten joints should be prevented from locking, but there is no problem with curling joints.

　　Warm reminder: Have sufficient warm-up before training. You should strengthen the flexibility of various parts. The training movements must be standard and correct, and do not blindly pursue weight.
