I also like playing ball, but my physical condition is not as good as yours, hehe. I have seen the method introduced by nba trainers in Sports Illustrated before, and I think it should improve the bounce. Just find a step about ten centimeters, stone steps or something, that is, toes can step on it, heels can step on the ground, toes can step on it to do up and down movements, or toes can do it point by point. 20 in each group. Do the third and fourth groups. Do it every day. And jumping stairs, which you should know. This is also the case. The trainer said that if you persist in doing it for 2-4 months every day, you will get obvious improvement. Later, I also asked the coach when I was working out. He said it was used to exercise the muscles of the calf and achilles tendon, and it should be effective. I didn't insist at that time, hehe, there was no result. You are in good health. You said you couldn't get stuck. I am strong, but I only have 1.74. My method is to go around to the front, then sit on him, and then stick my hands behind him so that he can't move. Short and thin, he is certainly not as strong as you. If you want to use your physical condition. If you can't catch the ball, you may not have enough strength. I suggest you go to the gym for a few months. Your weight, height and chest push should be at least 70, and dumbbells should be 12- 14 kg each. it wont hurt you to try it Practice the ball while working out. You can show your advantage in a month, hehe.
