Hello, everyone, I just bought a hula hoop, which is quite popular outside now, and there is a layer of foam outside. Ten yuan each.
It won't have a bad effect on internal organs, but don't use a particularly thick hula hoop. When turning, the body movements are easy to deform, which is not conducive to body shaping and weight loss! (Note that you can only exercise one hour after meals, and exercise at night is effective. Persistence is very helpful for thin waist. This is from experience. )
