First, you can run. Compared with other sports, running is the most uniform and common way to exercise, but it is also the most commonly used way for everyone. It seems that most of this way just exercises the legs, because after all, it runs with legs. In fact, when people are running, they exercise their whole body besides your legs. Because your arms need to shake or exert strength to keep your body balanced, and your waist is constantly shaking up and down, including the fat on your stomach. Running is not just about moving your thighs, but also your whole body.
Running is also the most common, and people use it the most. In fact, as long as the amount of exercise is achieved, it is also a very effective way to keep fit.
Followed by sit-ups. This is a kind of fitness that I like very much. Mainly to exercise people's back, but also to exercise the meat on the stomach. Because I have a lot of fat on my stomach, I like this kind of fitness very much. Moreover, this is one of the fastest and most effective ways to grow abdominal muscles. There is no doubt that people who often do sit-ups have developed abdominal muscles, which is more beneficial to their backs. The muscles of the back can also be solved by sit-ups.
Another way to exercise your back muscles intentionally is pull-ups. This kind of fitness mainly exercises the strength of people's arms, but the back can also be exercised because of this exercise. Because when you lift your body, your arms and back will work together.
