Skinny legs, doing squats is a good way, and you don't need too much strength and fatigue. You can also do it while chatting and watching your mobile phone. After squatting, pay attention to beating your legs and pinching your legs, otherwise your legs may hurt or grow muscles the next day. But it is unlikely to gain muscle, because losing weight means losing weight first and then gaining muscle slowly.
And skipping rope, skipping rope is the whole body moving, of course, legs are no exception. However, we should also pay attention to the method of skipping rope in the dormitory. If the dormitory is spacious enough and the ground is good, you can consider it. But if your dormitory is not on the first floor, forget it. Don't influence others. Don't let the people downstairs find you for a skin and bones, it's really a loss-making business.
There is also what we call "pedaling three rounds", that is, lying flat on the bed, legs up, pedaling up and down like a bicycle. Or lie flat on the bed with your legs straight and swinging from side to side, so your waist will be very tired. You should be able to hold on and be careful not to bend your legs.
There is also doing aerobics. I have seen a set of aerobics in Weibo before, that is, my legs keep moving and I can do it in the dormitory. Also, pay attention to sitting posture. When sitting, sit one-third of the stool, keep your waist straight, stand on your toes, or stovepipe.
Some girls should keep their mouths shut, and don't eat if it's too late, but they shouldn't go hungry just because they want to lose weight. After all, health is the capital of revolution. There is also the emphasis on persistence, not the use of heat in three points, but the long-term persistence to have an effect. However, I have to control myself for a while. Don't really get hurt, you're tired. I persisted until the next day, and my whole body ached, just like a basket case.
