For muscle training, most people will first consider the exercise of chest muscles and abdominal muscles, but after a long time, you will find that only the whole muscle looks the most beautiful, such as broad back muscles and beautiful arm muscles. Of course, you need the support of these muscle groups while exercising your chest muscles and abdominal muscles, so exercise is recommended. The best way of chest muscle is dumbbell flying bird (inclined upward and downward), which is much faster than flat pushing. The parallel bars flex and stretch, which will effectively shape the shape of chest muscle. As for abdominal muscles, do more sit-ups, you can refer to 8 minutes of abdominal muscle exercise and X abdominal muscle tear. As long as you persist, you will have obvious results. If there is no fat layer in the body, the abdominal muscles will be exposed soon, so you should lose fat. Wish you success!
Also, pay attention to stretching and rest after exercise.
