Three principles should be followed in fitness: concentration, large muscle group exercise and integration of stretching into exercise, which can effectively improve the efficiency of fitness. In our daily life, we all know the benefits of fitness, but many times we just talk about it every time, because we have no time and have never really exercised. However, these principles we are going to talk about today can not only save exercise time, but also lose efficiency.

First, focus. I didn't have much time to exercise. If you still think about some messy things while exercising, it is likely to affect the efficiency of fitness. Therefore, we need to concentrate on fitness and let the body follow our own ideas to exercise, which will also get twice the result with half the effort. Of course, in addition to fitness, we also need to be self-centered in our daily work and study, and we need to concentrate on things to do better.

Second, exercise large muscle groups first. There are several kinds of exercises in the gym, but because time is tight, you can exercise your big muscles first, and do the main ones first, such as squats, which can effectively improve your physical fitness and stretch your muscles. Of course, when we have no time, we must choose more important things to do first.

Third, integrate stretching into fitness. It's really a waste of time to do a full set of exercises in the gym, because you have to warm up first when you exercise, and then you have to warm up after you finish. These are all essential steps. If you don't have time at ordinary times, you can put it on fitness. When stretching, you can use fitness equipment to help, which can effectively save time. Never omit these actions.
