Precautions:

Squats are heavy, don't blindly increase the weight.

You must be careful when practicing without protection and help.

Obviously, barbells should not be placed directly on joints or bones, but on flexible muscles to improve endurance.

Let the barbell contact with the shoulder as much as possible to increase the contact surface, reduce the pressure, avoid the pain and maintain the stability of the barbell.

In addition, the barbell should be close to the total center of gravity of the body or pass through the center of the supporting surface.

In short, a clear placement position is the basis of barbell placement.

The right action.

It is wrong and dangerous to bend over and practice squats.

Be sure to look up when you do the action.

Reasonable action rhythm.

Don't put it down too fast or too low when squatting, otherwise it will easily damage joints such as knees and ankles.

The reason why the barbell is put down quickly is that the supported muscles are too loose.

The barbell is heavy and has a certain speed, which will lead to the inability to get up or slide.

The survey shows that barbell slippage occurs during lowering, accounting for more than 70%.

It is very important to protect and help when practicing squats. There are mainly two ways: "holding the waist" and "holding the bar".

Waist: Behind the practitioner, stand in the same direction, put your hands around the waist of the practitioner and squat together. Grip: Stand in front of or behind the exerciser and hold the barbell with the palms of both hands up.

Beginners use the weight 15-20RM to experience the action first, and start to do what they can, and don't blindly increase the weight. Practitioners should be cautious in the absence of protection and help.
