If you want to quickly increase the explosive power of your legs, you can consider jumping on the ground or stairs in the morning and evening. If conditions permit, it is better to tie sandbags. In addition, you can also go to the gym to practice squats and weigh your feet. Do all the movements as many times as possible, and you should do them as soon as possible, so that the explosive power can be improved quickly. Finally, the length of daily exercise can be determined according to your physical condition.
In addition, if you are skateboarding, straight leg jumping is also a good training method, which can comprehensively exercise the strength, coordination and flexibility of your waist and legs. The specific method is to dig an inch deep, so that your feet can easily stand in the pit inside, and then your knees will not bend, and you can straighten up and pull out the pit by leaning back. The main point of action is that the legs must not bend and the waist must not twist when exerting force. Maybe the height can only be raised by less than an inch at first, but with practice, it can be improved continuously, and then the depth of the pit will also increase.
There is such a way to train bouncing in Wushu. The so-called straight leg one foot, bent leg one foot. I believe this exercise method will definitely help you.
If you want to improve your physique and physical strength in all directions, I personally think skipping is a good choice besides running, swimming, playing ball and other traditional sports. Ten minutes of skipping rope is more than half an hour of running.
Finally, no matter what method, the most important thing is persistence. As long as you find the right exercise method and intensity and persevere, you will certainly gain something. I wish you success!
