By balls, I mean balance balls. I am sitting on one right now. At my desk, at work. It's a bit sore and not easy to hold your core upright for extended periods of time, honestly.
I sort of want to invest in a balance ball chair for my desk...it's the small changes to your everyday routine that can make a long-term difference, right?
I'm curious about this, too. Let me know if you make the leap.
