If this sounds strange feel free to say so. I work in front of a computer all day but I want to find some way to fit in some toning/strengthening during my work day. I was considering getting a stability ball and putting it in front of my desk to sit on (I also thought about kneeling on top of it) as I understand that just the act of keeping balanced on it can help to improve core strength & toning. Has anyone else tried this or am I crazy? If anyone has tried this what size ball would be appropriate and, dare I say, ergonomically correct for an average height desk? Last question, I saw one at Target from Reebok that has a weight in the bottom "to keep it from rolling away between exercises." Would that be a helpful thing or defeat the purpose of keeping your own balance?
By the way, I work out of my home office so laughing co-workers wouldn't be an issue (although my sister does work with me often & she would be making fun of me sooo hard core).
