What are the traditional good fitness methods?

According to my understanding, the so-called traditional fitness methods can be easily done. If so, my suggestion is to do more push-ups, because push-ups are simple and effective, which have a good effect on reducing fat, shaping and increasing muscle. In addition to push-ups, you can also do more sit-ups and do more sit-ups to say goodbye to the "general's belly" easily. In addition, squats and weight-bearing squats have a good effect on exercising leg muscles. You can also do pull-ups in your spare time, so you can have a better upper body shape!
