If there is no fitness equipment in the dormitory, you can effectively train your whole body muscles through self-weight training, such as push-ups, squats, frog jumps, supine belly rolls and so on.

There is a principle in training, that is, you must overload. Every time I feel pain in the training area the next day, it is effective. Pay attention to the supplement of high-quality protein before and after training, which can effectively enhance the muscle dimension. For example, you can eat more eggs, milk, chicken, fish, beef and other foods during training. After all, muscle growth needs raw materials. Practice three points and eat seven points, so if you want to have beautiful muscles, don't just concentrate on practicing and ignore eating.
