It is best not to lose weight on the treadmill, because the running belt angle of the treadmill is inclined. If you run for a long time, your legs and joints will wear out. Maybe you feel nothing now. When you get old, it will show up bit by bit! For your health, I suggest you go swimming to lose weight, because the effect of losing weight on land is "muscular" and "streamlined" in water! I hope it helps you!
