My conclusion is that fitness is mainly concerned with your own experience, not the task. Some people often specify exercise indicators and stop after exercise, but I think we need to exercise and feel whether to stop. Fitness is a process of repeating the same mechanical action. In this process, we will sweat a lot. Some people prefer the feeling of sweating after exercise, but some people don't like it, but they will feel sticky. It can be seen that for different people, fitness gives people different feelings.
Exercise every day can effectively improve our cardiopulmonary function. At the same time, the advantage of fitness is that we strengthen our physique and don't feel lack of energy when dealing with some things. If you can keep exercising every day, it is also a good pursuit of life, especially for people who are often at home, get a treadmill at home to ensure a different experience.
