Spinning is the best way to lose weight, because the range of exercise is the largest, mainly to exercise the muscles of legs and buttocks. But if you step on it hard, you can also exercise your waist and abdomen while swinging with your body, and your hands can also follow the music. For details, please refer to some sports riding related videos. And cycling is aerobic and can last for a long time. Like a pedal machine, it has a hydraulic effect, and the calf is prone to acid swelling. Usually, you can't step on it a few times, and few people take this equipment for long-term exercise. Consuming fat requires aerobic exercise lasting more than 45 minutes, and insufficient exercise time can only metabolize sugar in the body. As for sit-ups, they are mostly used for local body shaping.
