Intensive training can exhaust you every time. You are a little tired, but you can really strengthen your physique, such as jumping from music to music. Stick to it for a while, and you will find that your physical quality will be much better than before, but only if you know how to rest and replenish your energy and nutrition.
The explosiveness of power is actually a problem involving basic skills. The more solid the basic skills, the easier it is to exert strength, because the center of the body is stable and the axis is stable.
I personally summed up a method. Be happy when training, do it slowly first, and don't slow down any longer, so that the body can feel the shift of center of gravity, the feeling of feet pressing on the ground, and the continuous feeling. The slower it is, the harder it is to jump and the longer it takes. Of course, strength and speed still need to be done. But you can't be a good dancer if you do it slowly. After finishing slowly, you can practice the normal rhythm and speed up appropriately. The requirement is that there should be no omission in the process of action. No matter how fast the pace is, try to finish it. If you don't feel well, you should try again until you get used to the speed. At the same time, if you are full, you can speed up every process appropriately, but don't just want to speed up. Almost enough.
This kind of training doesn't need music, just a rhythm in your heart.
Also, if you want to dance well, you must grasp the details and don't let go of any details. When you think you dance well, you still have to find fault with yourself, even if you have the slightest illusion. This is the process of the dancer's ascension. Many details are often very important and will directly affect your future promotion, so don't ignore them.
One more thing, the problem of partner, many times speed, strength and explosiveness need a partner to complete. In order to improve better, a good partner is essential, but with a good partner, you should learn to use it yourself. After all, the cooperation between two people can be gradually improved.
