These are a couple videos of boxer Thomas “infamous_wu13” Wu keeping a 20-pound medicine ball floating in the air with a series of ultra-quick lightning punches. For reference, I tried picking up a 20-pound medicine ball once and threw my back out. Despite having just paid $60 for an hour of his services, my personal trainer just laughed in my face with his protein powder breath then attached two 45-pound barbell plates to his belt and did like a hundred pull-ups. Then he carried me to my car like a baby while I spit up on my shirt like a baby.

Keep going for the videos, and search #floatingballchallenge on Instagram if you want to see other people trying it.
