It will be effective to deepen the stimulation of the insufficient side by exercising the lateral abdominal muscles, but it will also cause unevenness in the long run. The most important thing is whether you are biased towards one side when doing sit-ups. You can feel it yourself. Remember to practice abdominal muscles by rolling your abdomen, so that the strength is evenly distributed on the six muscles in the upper abdomen. Work hard!

Belly rolling? How to do

Belly rolling is actually a formal sit-up. You can lie flat on the mat with your arms crossed on your chest, your left hand touching your right shoulder and your right hand touching your left shoulder. The purpose is to increase the weight above the abdomen and stimulate the abdominal muscles. Then your jaw will press on your collarbone and begin to compress your abdominal muscles (that is, the concept of curling up). Don't leave the mat on the lower back. Lift the part above the abdomen completely by the contraction of abdominal muscles. If you want to increase the difficulty, you can bend your legs 90 degrees, one group can do 25-30, and the other group can do 4-6 groups. If you want to make your abdominal muscles have the fighting ability, then the number of your groups should be increased to 120- 150, but the number of groups can be reduced to 3 groups. Finally, increase the weight, such as lifting a barbell on your chest. The weight depends on yourself.
