Sports belts were originally used only by professional athletes in weightlifting and other sports. In the weightlifting competition on TV, we saw that most weightlifters wore belts. The function of the belt is to support the muscles of the lower back when we lift (or pull) heavy objects. In modern gymnasiums, people like to use belts in sports involving only the waist. For example, use it when pulling hard, squatting, barbell rolling, and even standing and pushing shoulders.
Therefore, for strength trainers, once you use enough weight to make your lower back in danger of injury, it is best to wear a seat belt. The belt seems to be very helpful for squatting and pulling hard, so most exercisers wear it. At this point, we do find that using a belt can make the force feel better and make the room look easier and stronger. Can help protect the back, as well as lumbar vertebrae and other parts, can help reduce the probability of injury.
Waist protection is also called waist seal and belt. In sports, a belt worn around the waist to protect the waist from injury, warmth or some special functions.
