We speed up metabolism.

2. Pump your muscles! The more muscle a person has, the more metabolically active they are. Even at rest they burn more calories than fat. 0.5 kg of muscle per day burns 6 calories, 1 kg of fat - 2 kcal. If you replace 1 kg of fat with 0.5 kg of muscle, you will increase your BMR by 8 calories per day! When people lose weight, they not only shed fat but also muscle, which in turn kills metabolism in the bud. But moderate pumping of muscles will help not to ruin the metabolism, but to disperse it even more!
