Shaping fitness is not a simple matter. How to scientifically shape fitness? I have some suggestions for your reference:
1. If you want to keep fit, you must first have a good body, a healthy body, and to have a good body, you must start with diet and living habits. Eat more green food, such as fruits and vegetables, and eat less spicy and high-calorie junk food. In daily life, stay up late less and insist on going to bed early and getting up early.
2. Exercise regularly and reasonably. Shaping fitness is no better than general fitness, which requires a scientific training plan. You can consult some professionals and fitness coaches to make a reasonable, scientific and feasible plan according to their physical fitness, instead of letting their preferences and temperament arrange it. This will have no effect and may hurt their health, so as not to miss it.
3. Shaping and fitness is not a day's work. I think it should be more like a living habit and a state of life. Therefore, scientific shaping and fitness needs to keep exercising every day and persevere according to the formulated plan, instead of giving up halfway. That won't have any effect.
These are my suggestions on how to scientifically shape and keep fit. You can try it and see if it helps you.
