I used to go to the gym to exercise, and the coach told me that anaerobic sprinting would make my legs thicker and aerobic exercise would be thinner. Just look at the bodies of 100-meter athletes and marathon runners. Sticking to cycling can help you lose weight, because cycling is an aerobic exercise. If you ride for about 20 minutes every day at a speed of 10 km per hour, this riding speed will not make your legs feel particularly tired, so it is an exercise that consumes leg fat and can improve leg muscle strength.
