Here's a challenge for anyone who wants a go. The idea is very simple and is a great workout if your accuracy is off.

Throw a single tennis ball against a wall 10 times in a row as fast as possible. You don't necessarily have to catch it each time but thats much faster than picking it from the ground.

Distance can be whatever you like, but 10-15m works best for me. Obviously the closer you are, the less time the ball is in flight. But you also have less reaction time for the catch. For any "official" time, I would say no closer than 10m.

Time is measured from the moment of release to the moment you touch the ball on the return bounce of the 10th throw.

On the off chance anyone would like to compete,  I threw 29.02 seconds from 15m today. Finally broke 30 seconds haha

Here's the video

You can also just see how many you can catch in a row without letting the ball hit the ground.

Thanks for the link, I figured someone had to have done something similar.

Ill have to try the 1 minute challenge next time! Keeping that tempo and consistency for a minute will be hard.
