The resistance should not be too light, standing and riding consumes more than the mount. Moreover, the rhythmic music and atmosphere of spinning bike will be more effective than the boring treadmill. However, bicycles will do more harm to the knees. Of course, treadmills can also hurt your knees. This means that when you exercise by yourself, you should have the right posture and follow the guidance of the coach. In addition, pay more attention to yourself and stretch for half an hour after riding a bike.
