Matters needing attention in the use of fitness belt
1, fitness belt belongs to protective equipment, so don't rely too much on it. In the early stage, I still aimed at getting familiar with the essentials of movements and learning how to exert my strength, and refused to be an "equipment party."
2. We should follow the principle of "soft belt and hard belt". If the early stage is soft, the body can adapt better. If the training level goes up, change to a harder belt. Fitness level is positively related to belt hardness.
3. Little friends with old waist injuries should recover first, and then slowly put on the counterweight. Never carry the load directly with your belt. The fitness belt only plays the role of icing on the cake.
