Let me introduce you to several simple chest exercises that can be practiced at home and have good results: 1) Push-ups are dynamic exercises. Here is a static push-up. Do push-ups When the body descends to the point where the chest will touch the ground, the pectoralis major muscles will be extremely tight. Keep this static posture for 8- 10 seconds or a little longer, and then relax. (2) Stand facing the wall and raise your arms horizontally in front of you, so that your fingertips will touch the wall but not the wall. The whole body is straight, the upper body leans forward, the palms are attached to the wall, and the fingertips are facing up. Bend your elbow. The upper arm forms a 90-degree angle with the forearm. Keep your upper body close to the wall. Keep your arms bent to support your upper body, and don't lean against the wall. Keep your pectoralis major very tense. Keep this static posture for 8 ~ 10 seconds or a little longer, and then relax. (These two movements will not easily deform your chest muscles. ) I also give you a suggestion, such as 1, 3, 5, do the anaerobic exercise I introduced to you, and do simple aerobic exercise on 2, 4 and 6, such as running, skipping rope and swimming. This is because muscles need rest. Practicing aerobic exercise while resting abdominal muscles can reduce fat and make abdominal muscles more obvious.
