1. Before buying, consider your own needs and ask yourself what effect you want these products to achieve. 2. Don't expect too much from the effect of the product, lest you can't reach your expected effect and cause your psychological imbalance. Have confidence in your body. 3. Because it is a close-fitting product, the choice of material is very important, and cotton is better for the close-fitting part. 4. Not necessarily expensive products are more effective. Shop around and buy products that suit you. 5. Buy products and brands that have no problems. 6. Don't buy too tight products for quick results, so as not to hurt your health. 7. When using the product, treat it as an auxiliary product, and don't treat the product as the only bodybuilder.
