If you just want to lose weight, a hula hoop can solve it.
However, the correct way is to lose weight all over the body first, and then focus on losing weight around the waist, which is healthier.
Sit-ups+recumbent pedaling (people pedaling in bed)+hula hoop can effectively reduce waist fat. You can have a beautiful mermaid line.
Sit-ups per group 15, recumbent pedal per group 100, hula hoop per group 100.
Complete a set of breaks 10 minutes. Continue, 3 groups a day, can effectively lose weight.
I have been there before. Trust me.
