In the gym, you can often see some great gods, all of whom are squatting and pulling with fitness belts. The reason why I use this thing is that squatting and hard pulling will use a relatively large weight, and using a belt can help you keep your waist nucleus stable and not bend or shake. Because once you do these two movements, if you can't keep your waist stable, you will be very fragile. Especially hard to pull, if you can't stand straight, it will especially hurt your lumbar spine.

Secondly, the great god uses this thing to help them improve their sports performance, especially when you tighten your belt, which will lead to an increase in your abdominal pressure and you can squat or pull more weight. Just like when some people lift iron, it is a truth to force them to like to hold their breath. Other protective measures, such as wristbands, are similar and can help you improve your grades.

Finally, many great gods may be injured because of long-term training, especially many people have lumbar injuries. According to a coach I know, he wears a belt every time he squats, just to prevent the recurrence of old injuries.
