Please note the following points:

1. The flywheel weight of spinning bike varies greatly. Under the same resistance section, a spinning bike with a heavier flywheel will bring you greater exercise intensity.

2. Spinning bike is basically adjustable in resistance. At the same speed, the greater the resistance, the greater the exercise intensity.

You use different postures to exercise different body muscles. If you ride in a sprint posture, your legs will get great exercise intensity.

We say that the best way to reduce fat with oxygen is to use appropriate intensity and increase the time of continuous exercise. This method is suitable for all aerobic fitness equipment. Whether you are running, riding a bicycle or riding an elliptical machine, as long as you grasp the principle of "appropriate intensity and enough continuous exercise time", then the purpose of reducing fat can be achieved. If you lose fat in your legs, you will naturally lose your legs.

If you are eager for success and blindly increase the intensity of exercise, for example, you can push hard with great resistance, then there is no doubt that the result must be a pair of strong legs. Because you give too much stimulation to the leg muscles.
