If you just want to exercise in the dormitory, or you really don't have the conditions to go out for activities, you can refer to the following suggestions.
When I was in college, there were eight people in the dormitory, a room of less than 20 square meters, four bunk beds, four combined cabinets, a * * * eight-compartment, and then a table, which could seat about six people, and then the table was placed by the window, with the window facing the door. Well, that's about all the hardware in the dormitory. As for everyone's personal belongings, they are basically stuffed under the bed.
Then the public space of the bedroom is the position from the door to the table, about four square meters. I think the pattern of most bedrooms should be the same, so I will analyze it like this.
First of all, since you want to keep fit, you have to choose some suitable exercises according to your hardware. In such a small place, skipping rope or something is definitely not acceptable. Even if the brothers in the dormitory let you jump, you probably won't agree downstairs. So what should I choose? There are many kinds of answers, all of which are practical.
Push-ups, this doesn't take up space, does it? How big a person can be, a small one is enough. The main exercise is the chest muscles, which can also have a certain exercise effect on the waist, abdomen, back and arms.
Sit-ups take up the same space as push-ups and do not need any special tools. Buy a yoga mat at most. Everyone should know this action, mainly for abdominal muscle exercise. Simple and effective, but many people don't know how to do it, so it should be noted that the action must be exerted on the abdomen. Don't put your hands behind your head and pull your head hard. Be careful to tear the cervical spine. The best position for your hand is.
Squat, this action takes up less space, as long as you can stand in your personal position. This action is of course aimed at leg exercise, but you should also pay attention to your posture when doing the same. You should try to keep your upper body vertical to the ground, hold your head up and chest out, and put your hands behind your head. This is no problem. However, for the controversy of this movement, some people say that doing too much may hurt your knee, especially if you bear another load. However, I think as an amateur, just do whatever you want. Basically, if you don't persist, you will get hurt.
Besides, if you can, you can buy some equipment, such as dumbbells and arms, which are very effective fitness methods and can be carried out without particularly large space. But despite these methods, if you don't do it, it's still useless, so persistence is the key to fitness.
