So I've been seeing suggestions from fitness folks lately to swap out your office chair for a stability ball in order to burn extra calories and strengthen your core. I think it's a sign of how far I've gone down this road (or as one of my friends says, 'drank the koolaid') that I'm actually considering doing this.
My question is, would this be considered too insane by my coworkers? And does anyone know if the effects would be worth the switch? Has anyone actually tried this?
TIA!
