The order of knee influence from big to small is:

Usually: running > elliptical machine > cycling?

However, there are also some special circumstances that need to be considered, such as too high damping load of ellipsometer or riding with high transmission ratio for a long time, too high transmission ratio when climbing, and the pedaling frequency is less than 60 rpm, which will cause damage to the knee.

The order of fat-reducing effect from high to low is:

Running > elliptical machine > cycling In theory, the more muscle groups you participate in per unit time, the better the fat-reducing effect will be.

Elliptical machine belongs to aerobic exercise. Aerobic exercise can reduce fat. It is recommended not to adjust the resistance too much when using the elliptical machine. If the resistance is too great to trample, it is better to lift your legs and exercise your muscles directly.

So my suggestion is to adjust the resistance to a level that is not very laborious. You can do elliptical exercise for 20 to 40 minutes every day, and you must cooperate with the stretching action of your legs after exercise, otherwise you will feel that your muscles become bigger when your legs are congested.

Now paste the stretching action.

Exercise must be gradual and pay attention to safety.

Please adopt it. Thank you.
