I divide fitness into two stages. The first stage is to get close to the goal (find the muscle line you think you want to achieve and keep exerting yourself). This stage is progress and hard work. ) The second stage is maintenance. When you reach your goal, keep it up. This stage requires perseverance. The basic state is that fitness plays a role in eating. This is not difficult, but it is necessary. Maybe you are still in the first stage. So keep spitting! Personal opinion: Joline's answer is very professional. For me, all the plans are not fun for fitness people. He said in it that the problem of excessive exercise is indeed a warning from the body from a scientific point of view, but I always think that human potential is unimaginable. It seems that I have a tendency to be abused. I threw up and went on working. I think fitness is very interesting. Especially for people who just want to exercise, all this is normal. Don't be afraid, and don't make excuses. Compared with me and my friends, I am a' freehand fitness' and have no dumbbells so far. My friend belongs to the young master type, so I found her mother and got a vip card for fitness. Some people are predictable. My friend may never have a good figure because I know him. The reason for this example is that your goal is to be in good shape, and you vomited a little at first, so there is no need to worry. What scares me is that you belong to my friend. This is only about my friend's physical fitness, not his character. The state of fitness is the same for everyone, just like eating. Stop when you are full and eat when you are hungry. The state of fitness is different for everyone, just like eating. I don't know if you are hungry, only you know. Exercise is as common as eating. Don't treat it as an unusual thing. Too serious, people will become stupid. If you know when and how to measure yourself, you must practice.
