2. Jump at least 20 to 25 cm from the ground. If it is easy for you, you can jump to 25-30cm. When you are in the air, you need to put your hands behind your back. When landing, finish it once.
Next, just repeat the above steps! ! !

The practice of leapfrog is necessary to improve the jumping ability, because it is a way to train strength after all. Besides, there are other ways.
The first method, which is the most effective and the most difficult, can improve your bounce in a short time. Specific practice: dig a pit, about one meter deep. Tie a 5 kg sandbag to your leg and jump into the pit. Try to jump out of the pit with a heavy load. After half a month, dig the pit 20 cm deep, increase the load by 2-3 kg, and continue to practice. This cycle, and finally when you can't bear the load or jump out of the pit, practice stops here. Take off the load and try again to see how high you can jump.
The second method, the effect is not obvious, but it is easy to realize. Specific method: Tie a rubber band on your ankle and jump vertically in situ. Practice for half an hour every day. But I feel that this method is not effective.
Good luck, future sports star!
In order to develop explosive force, we must increase muscle contraction strength and working distance and shorten working time. In strength training, it is necessary to use small load machinery for rapid exercise, and gradually increase the load to improve muscle contraction strength without reducing the speed. The technical action of "leaning back" just mentioned is mainly to increase explosive force through muscle contraction. The increase of strength can enhance the control ability of technology, so in the usual training, we should not only work hard on technology, but also work hard on increasing explosive force and improving muscle contraction speed. Practice has proved that high-intensity explosive force is an essential factor to improve performance. So how to improve the explosive power? (1) Change the load and speed. (2) Strengthen professional technical training, improve muscle control ability and relaxation ability before action. (3) The initial length of the muscle, only when the stretched muscle contracts, has faster speed and strength. (4) Relaxation exercises after strength exercises.
Among the factors of explosive power, power plays a leading role, so the growth of power contributes to the development of explosive power. But strength is by no means equal to explosiveness. In other words, in actual combat, you don't have the strength to apply technology well. The explosive power of a judo athlete can only be brought into full play by combining basic strength with speed, skill and agility. Some people can lift quite heavy barbells, but once they wrestle, they can't, specifically because of the lack of special strength. Judo athletes need strength, speed and endurance in confrontation. Some of our athletes feel that their strength is not bad, and the key lies in their special ability and quick strength. In the future training, we should pay attention to improving the special strength on the basis of transferring a set of strength to the special strength.
