The secret of perfect abdominal muscles

● When rolling abdominal muscles, the feet should be fixed.

● Don't move up and down quickly.

● It is not good to do too much. The key to exercising abdominal muscles is "quality is not weight".

● Many people misuse the relative muscles of the waist, shoulders or neck when doing the above actions. For example, if you want to practice your lower abdomen, you should try to relax the muscles in your lower back.

● When practicing, you must use the trained muscles to exert strength and avoid using other muscles to provide strength. For example, when we do leg lifts to exercise the lower abdomen, we must first tighten the muscles of the lower abdomen, and then use this group of muscles to drive our legs to lift. As for practicing the upper abdomen, you must use the upper abdominal muscles to drive your body up.
