Spinning bike is a scientific experimental design, which can achieve the maximum fitness effect by adopting the method of artificial mechanical engineering and choosing something that meets the requirements of human body and does not disturb the waist. In the leg-centered exercise process, the muscles of hips, waist, back and arms can be fully exercised. Therefore, spinning can effectively lose fat in many parts of the body. But moderate exercise is necessary, and scientific methods can play a role in fitness.
Treadmill mainly exercises legs, and arm swing will also exercise. Therefore, the treadmill mainly reduces the fat in the legs and arms, and has little effect on the fat in the waist, abdomen and back. Besides, treadmills are difficult to maintain.
