2 Dora weight Many people have insufficient waist strength, which is one of the reasons why the hard pull weight can't be pulled up. When wearing the belt, the waist is wrapped by the belt, which can provide stronger core stability. During abdominal breathing, the abdominal bulge will squeeze the belt, and the internal volume of the abdominal cavity will become smaller, which will obviously increase the internal air pressure, thus contributing to the stability of the lumbar spine, supporting the core, protecting the lumbar spine and making the upper body a stronger rigid support. So that when we pull hard, we can pull more weight.
Do you have to pull hard with a belt? You don't have to pull hard with a belt. In low-weight hard drawing, there is no need for a belt, just keep the action correct. Because wearing a belt will affect the exercise of the core parts, it is difficult to strengthen the core strength.
However, when the ratio of load to self-weight reaches more than 1: 1 or 1:0.8, you can consider using a belt, which can better protect your waist, let yourself pull up more strength and enhance the exercise effect.
Can the belt prevent waist injury? Neither pulling nor wearing a belt can prevent waist injury.
The belt can increase the air pressure in the abdominal cavity, thus enhancing the stability of the core, giving better support to the waist and reducing the risk of injury to the waist due to excessive load. But this is not to prevent injury, if the action is not correct, it will still lead to waist injury.
