This figure doesn't need to lose weight. . . . . Let me help you talk about your muscle building plan. First of all, you should make sure to exercise more than three times a week for more than two hours each time. After changing clothes in the gym, you should go running. Run at a speed above 10 for about 5- 10 minutes. Then you have to do anaerobic training, that is, equipment training. To put it bluntly, it is muscle training. Personally, I suggest you do chest, back, shoulder and leg training. I don't know here, and then do abdominal training. There are many abdominal muscle training on the Internet, depending on your ability, do 8- 10 movements, with 20-40 movements each. Before that, you can replenish water. Then go running, running at the speed of 8, or faster if you like. It is best to run with speed and speed. 1 hour Don't drink water during and after running. Run 1 hour. Then take a bath. . . . If possible, drink some protein powder or skim milk after taking a shower. In this way, fitness is a long-term plan, and a healthy attitude towards life is the most important. I wish you success!
