Unfortunately, our gym attendant has cleaned the floor incorrectly, which is why it's very slippery and has hardly any grip. We are also the last group to use the gym in the evening, so it's also very dusty when we train. I've already tried briefly mopping the floor before practice, but that doesn't help because of the incorrect cleaning. I'm scared to hurt myself when I fully commit to a jump (a teammate twisted his ankle when the gym was freshly "cleaned" and he jumped). At a tournament we were in a different gym, but there I also had the feeling that I kept slipping. What do you do when the ground is extremely slippery? Is there some hack to get your shoes more grippy?

Hey Guys, Week 2 of the vertical jump program is online now! 💪📈 You can find it here. Let me know about your progress and put your questions in the comments! 📱 David

What is the reason when I jump I feel pain in my back. Any streching exercise that helps me.

I as a setter am really struggling to reach all the way back to set the ball so I was wondering if anyone knew any good stretches to help me reach behind me

I feel like I'm not hitting the ball too hard so what should I do and what should I practice more?
