This has something to do with your physical fitness and exercise. My husband rides a bike 1 month, about 5 knots a week, and loses weight in one month 18 kg. According to this situation, two months is almost the same if the diet is reasonable. As for me, I ride my bike about three times a week, and then I have four classes on Wednesday. I have never lost weight, and I am still the same. Also, when the landlord pays attention to the bicycle, the resistance should not be too great, which is easy to thicken the calf ~ ~
