Chest muscles (key) Back muscles, abdominal muscles and two or three head exercises
Muscle depends on practice for three points and food for seven points. According to your height-to-weight ratio, you are overweight. I suggest you do more degreasing exercise before strength training, that is, aerobic exercise, which can reduce excess fat on your body. If you lose fat, your muscles will naturally show up. If you only want to sculpt muscles and don't care about strength, I suggest you do more muscle endurance training, so you don't have to go to the gym, which will only make you a muscular strongman with developed limbs. Muscle endurance training is low weight many times. For example, just exercise your chest muscles and do push-ups, three groups a day, 50 in each group, to make your chest muscles clear, but without exaggerated thickness. Or do muscle endurance training every day, so that the muscles developed in this way are explosive and fast, just like in Bruce Lee.
