How to put on a weight training belt
Check that your belt is positioned correctly on your hips. If it is too high on the lower belt, it can force your hips to turn and hollow your back.
In addition to placing it over the glutes, be sure to centre it precisely. Ensure that the two ends of the belt are at the same height. Otherwise, the weight will exert unequal pressure on your body, which can cause imbalances, and in the worst cases, injuries.
