Especially diet, is actually quite important. It is possible that if you eat something wrong, it will ruin the exercise results for a few days and feel that it is useless to exercise for a few days. Therefore, a good fitness method must develop good eating habits.
In terms of diet, I think first of all, you should not eat anything particularly high in calories, and don't drink those sodas or something. Because things with high calories may cause your muscles to form less easily, and then they may destroy your muscles, I think I should try not to eat those things with particularly high calories and not to drink soda like Sprite Cola.
Usually try to eat chicken breast, or boiled meat, and some fruits and vegetables. I think as long as we control these things reasonably, don't eat or drink, and then stop eating and keep eating.
And I also think you can choose beef, because beef is a very good thing, and then it can effectively replenish protein in your body, but it won't gain weight or anything, so I think you can try it. You can also eat more tomatoes and vegetables. These things are good for your health and fitness, so I think you can eat more.
Fitness is actually a particularly hard thing. Many people may like fitness very much, but they don't stick to it. Many people feel that fitness has no result. I think the most important thing in fitness is persistence, and the most important thing is to persist.
