First of all, skipping rope is a good way to lose weight, but! !

Your method is wrong! !

The correct way should be! ! !

Each class is 400-800, 4 classes a day, with an interval of 5- 10 minutes, during which you can do sit-ups. Drink some water.

Hold on. If you are used to this intensity, please extend the time yourself.

Start with at least 40 minutes every day. At least 120 minutes should have obvious effect.
