2 provide stable support and protection for the spine, reduce the pressure on the intervertebral disc when carrying weight, protect the spine and prevent injury, especially protect the spine when squatting hard, and make up for the shortage of supporting muscles around the bones.
The belt can speed up the squat and stand up and enhance the explosive force.
The suggestion is to use a belt when lifting heavy objects, especially when the spine is stressed heavily.
