Let's talk about the pull-ups first. Pull-ups train the stretching muscles of our body, including forearm flexor and many other muscles on the arm, as well as biceps brachii, brachialis, latissimus dorsi, trapezius and rotator cuff muscles at the back and back of deltoid.

Of course, the core muscles of your abdominal muscles also need to exert their strength steadily in the pull-up training. So can pull-ups exercise abdominal muscles? Of course. However, it has no special core training movements and is more efficient. For example, the efficiency of doing pull-ups to exercise abdominal muscles is much lower, both of which are hung on the horizontal bar.

Free-hand fitness is generally based on self-weight, but some muscle groups are difficult to train by self-weight, such as the middle and back of the deltoid muscle of the shoulder. For these two muscles, handstand is the main training method in the prisoner's fitness system. Those who have tried it will know that it is not easy at all, and it is much more difficult than dumbbell lifting and bending over lifting.

Any training mode should pay attention to integrity. If you only practice your favorite parts, it will make your body uncoordinated, which will not only affect the overall beauty, but also have other effects on your body. So if you need to practice abdominal muscles or chest muscles, don't just focus on these two parts. Occasionally practicing other parts of the body will also strengthen the parts you want to practice, especially the legs. Don't skip.

Everyone in the family can become a fitness expert. As long as you can persist in taking a little time every day to focus on exercising your body, I believe that you can let everyone see your changes in less than a month.
