Yes, but the effect is not very good. It is suggested to keep jumping continuously, so that the effect will accumulate faster day by day. If it's a day apart, you just need to slow down. You can eat a good posture, which helps to improve metabolism and speed up weight loss. In addition, you can also do Voldemort's static movements. Voldemort is still, stirring the muscles of the whole body to maintain stability, which can make the whole body move, especially thin waist and abdomen. Although the process is difficult, the effect is extremely obvious. The purpose of Voldemort's training is to resist gravity and bending of the body. Abdominal muscles and back muscles support the lower spine between the pelvis and ribs, so the muscles in this area will be particularly tight. Because of its static characteristics, it will not cause back strain like sit-ups. One group needs to be still 1 min, and do 3 groups every day.
