My friend, you are on the right path. The male dog waist of a boy is equivalent to the peach hip of a girl, which is very important. I believe every boy wants to practice. If you don't want to go to the gym, you can. There are many other ways to practice, and it is great that you choose the continuous period of summer vacation.

The first thing you need is to buy a yoga mat, and then download a fitness APP. As long as you take this small step, you have already succeeded more than half. Be sure to do 10 minutes of warm-up preparation before each exercise, so that you are not easily injured, and then insist on running for half an hour. After these two steps, you can start formal training.

In addition, before that, you need to be mentally prepared, that is, the male dog's waist is not so easy to practice. If you are fat, you need to reduce fat first. You must reduce body fat to a certain extent in order to have abdominal muscles. After all, no fat person can have abdominal muscles, right? Then you need to choose a set of high-intensity abdominal exercises, about 6 movements, 20 movements each, and 5 groups each.

At the same time, you must keep on doing it. The first action: bend your legs and lie on the yoga mat, and do half sit-ups by abdominal strength. The second action: put your hands on the ground and push your feet back and forth repeatedly. The third action: sit on the yoga mat and do leg stretching and kicking exercises only by hip strength. The fourth action: touch the ground with both hands and feet and walk back and forth on the floor in the form of flat support. The fifth action: the whole body lies flat, the legs and abdomen are kept at 90 degrees, and the upper body is supported by abdominal strength. The sixth action: flat support. If you don't know much about these moves, you can find a tutorial online, but you must stick to it.
