Four guys holding exercise balls run into each other at full speed and one of them gets launched across the gym floor.
Nobody wants to play with dirty equipment. Guys can now clean their balls so they are more enjoyable to play with.
A group of kids set up their buddy to get an exercise ball to the face.
His buddy hits a golf ball at the wall and it comes back hits his buddy in the head.
He only swallowed a couple in the making of this video.
His dad was clearly not impressed.
As soon as I saw the glass doors I knew what was going to happen.
Ouch, that's going to leave a mark!
Marines got the best moves.
It takes a delicate hand on the controls of this rig to pull off a trick like that.
