If the muscles are tight, massage them first, otherwise it seems difficult to lose weight.

Recently, riding a bike upside down in bed seems to have a good effect. And this is very simple, that is, lying on the bed with your feet straight and your body at 90 degrees, and then imitating the action of riding a bicycle with your feet ... about 30 to 50 times. Personally, I think it is simple and effective, so I might as well try it.
