After long-term fitness training, the body's muscle mass will increase, and regular exercise will make sebum well controlled. Muscle growth is because the body "adapts to new changes" in order to adapt to this intensity, while fat reduction is because regular exercise makes the body have a good metabolic level and the body has no excess heat accumulation.
After stopping fitness training, we have to admit a cruel fact. Stopping fitness training means that muscles will gradually shrink and sebum may slowly accumulate.
This is because the body has a strong physiological inertia. After stopping training, the muscle "feels" that it no longer needs such a large piece to meet the training, so it will gradually shrink.
The increase of sebum is due to muscle atrophy, and the metabolism of Xincheng will also decrease. In addition, irregular exercise consumes calories, and a little carelessness in diet will lead to excessive fat accumulation.
