Tendons grow in the womb and cannot be changed by exercise. In addition, the muscles are obviously underdeveloped. Add some muscles to see if they are really connected.
If you want abdominal muscles, you must first have a thin waist. When the physique is lower than 10%, the abdominal muscles will basically be displayed, that is to say, everyone has abdominal muscles and everyone has a horizontal line. It's just that everyone's abdominal muscles are different in size and fat, and they can be exposed or not. As long as you are thin enough, your abdominal muscles will be exposed to outsiders.
Extended data:
Exercise abdominal muscles need to pay attention to:
First, frequency:
Exercise your abdominal muscles every other day. Although many people do hundreds of sit-ups at a time, I suggest you choose the 2 14 exercises that are most effective for you, and only do three groups, 30 to 50 times in each group, and each group should be completely exhausted.
Second, the weight:
The greater the weight used by abdominal muscle training, the greater the possibility of irregular movements and the thicker the waist. The idea that gaining weight can burn more fat is wrong. So I suggest you use tension and control instead of weight bearing, and tighten and stimulate your abdominal muscles with your mind.
Third, the state is correct:
When practicing abdominal muscles, keep the whole group of abdominal muscles constantly tense, and don't let them relax at the beginning or end of the action. Always be completely exhausted, and each group should be completely exhausted. Don't count the times, keep doing it until you can't contract your abdominal muscles anymore.
