Glover's Balls by Jeff Glover

A nice way to practice movement

I personally like training movement like this with an exercise ball. I’m old and busted up, but found it makes a big difference to my movement and general health.

Good for balance

I have some exercise programs using a Swiss ball already, so it's cool to grab a bjj-specific one

Helps with coordination and balance. It’s lots of fun and a good core workout as well.
