Yes, abdominal muscles belong to the small muscle group of the body and have good endurance. Multiple times and multiple groups are more beneficial to the growth of abdominal muscles than large weight.

The above actions are aimed at the training of upper abdomen, lower abdomen and external oblique muscles. Do 3 groups for each movement, each group 15 to 20, and one group rest for 30 to 60 seconds. Precautions: Exhale from the mouth when exerting force, and at the same time, the abdomen will contract forcibly. The neck must be relaxed, move slowly and feel the force exerted by the abdomen. If you want to have clear abdominal muscle lines, you must reduce the body fat rate. I am a professional fitness instructor and bodybuilder.
