First of all, skipping rope can lose weight, and jumping on two legs is better (personally, ha). Jumping began on the 7th of this month. I jumped 2 1 today, almost half a month. On the evening of the 7th, he weighed 78.8 kg. I just gained 74.7kg today and lost almost 4kg. How can I put it? The efficiency is average. I dance more, one hour at a time. Of course it's not continuous. Jump 200 times. Because the one I bought with digital display can calculate quantity, calorie and time. I keep dancing for an hour every day, and the total is 8000 (don't think 8000 is too much, it's not difficult for you to dance for a long time). If you eat, you should control it. Eat slowly, don't eat too much, it's definitely no problem to keep on losing weight, but I think some people only adjust to 3000. I think losing weight depends on personal physique, hospitals and drugs. I strongly advise you not to try, it will cost money and harm your health. The scientific method of losing weight should be exercise plus reasonable diet, and the most important thing is persistence. Good luck.
