Riding a bike is a good way to lose weight. When riding a bike every day, the medium speed is fine. Don't rest for 40 minutes. Slow down in 40 minutes. As long as you ride for 4 hours, it will work on the same day. I once rode 50 kilometers+more than 6 hours. My leg is a little swollen. I looked a little thinner before I went home to sleep.

Step on it slowly, and you'd better set the speed a little harder. If you step fast, you will exercise your muscles in a short time, increase your metabolism and help burn fat. However, the meat with changed muscles cannot be thin. At this time, the muscle part can't be thinner. (Note: So do it slowly. A little more strength will hurt your muscles. )
