Personally, I think the most effective way to reduce your stomach and legs is to lie flat and ride at high altitude, which can reduce 500 legs and waist a day.
To lose weight, you still have to control your diet. In China, it is 140+ 15+ to eat eggs, milk and porridge every morning, a steamed bun or a bowl of rice at noon and an apple when you are hungry in the afternoon. If you can persist, don't eat anything. Believe me, you will lose weight soon.
I wish you success in losing weight, health and beauty.
