If you work hard, you will have a chance. If you don't work hard, the chance is zero, so you have to keep jumping.
How do you think we can get higher? I'll give you some advice. It's best to drink a bag of milk after skipping rope every time. A reasonable diet and enough sleep will make you grow faster. Do not take medicine. If there are side effects, you can't afford to lose them if you eat them badly. There is not much research on fruits and vegetables. I eat all fruits and vegetables. As long as it is green food, I should eat meat. You must not be hungry when you grow up.
Finally, answer double shake. This is actually very simple. Try the following methods.
1, warm up well, don't jump double shake before the activity starts, you can jump single shake 10 minutes.
2, and then the correct posture, two arms clamping (two pieces of tissue can not fall off in the early stage), wrist force (mainly), palm down, the most important thing in double shaking is wrist force, the jumping height is high first and then low, and you can master it freely with slow practice.
If there is anything you don't understand or can't read, you can go to China Skipping Network Forum to see the basic video tutorial. There are many teaching methods of pattern skipping, which I hope will help you.
