Leg lifting can fully stimulate the movement and exercise of thigh muscles when the thigh is off the ground, so that the thigh muscles can continuously contribute to maintaining the balance of the body in a short time, thus making the blood circulation in the thigh faster, quickly digesting the accumulated heat and fat in the thigh, providing energy for the body, and effectively reducing the fat on the thigh. However, when doing leg lifts, we should pay attention to make the muscles of the thigh feel a little sore as far as possible and then change the other leg to exercise, so as to ensure the fat of the thigh to burn quickly.
