Last week I was on the receiving end of a challenge to try something new: replace my regular office chair with an exercise ball and compare the effect that doing so had on posture, performance, and general health and wellness (or something like that).
I have a really nice office chair that I got about ten years ago when I started sitting in a chair for most of the day. Perhaps coincidentally, ten years ago is when I started to develop my “Rice Crispies” spine syndrome (Snap, Crackle, Pop), but I don’t blame the chair for that as much as I do all the time spent sitting in it. At any rate, I do still have some back issues so I thought it would be an interesting trial.
On monday after morning workout I swung by Academy and picked up a ball at 50% off, owing to the fact that someone had apparently returned a ball but kept the tiny hand pump and accompanying DVD. Total cost: $7.
virtually worthless pump and DVD not required

The old and the new

My first observation was that most people trying this do not need a very large ball. A 75cm ball is simply ginormous when fully inflated, but fortunately there seems to be a very wide range of useful inflated sizes. I Inflated my ball to somewhere around 60cm and that worked reasonably well, though it was probably still a bit too large for ideal ergonomics and I did catch myself slouching forward every once in a while (might need to try letting out more air).
After sitting on the ball chair for a while I realized that I probably would need to keep my office a bit cooler than was necessary with my regular chair. My regular chair is a really nice chair (I spend a lot of time in it after all) and it has a permeable mesh seat and back surface. This mesh has the significant advantage of allowing your body to breathe (or perspire) while seated. The exercise ball is necessarily impermeable to air (and also water vapor), so if your body tries to regulate its own temperature via the normal mechanisms then a build up of sweat in the area in contact with the ball is a distinct possibility.
While working I found myself periodically rolling back and forth and side to side, and also bouncing up and down a bit. These subtle exercises are probably good for the body, but they can be distracting to people on the other end of video conference (“uh, are you bouncing or just really excited or something?”).
Pros:
- Inexpensive
- Seat height is adjustable by inflation/deflation
- Subtle strengthening exercises happen naturally while working
- You’re sitting on a ball while working (is life good or what?)
Cons:
- Impermeable seat surface (a.k.a. booty sweat)
- Slouching is still possible, especially if the ball is too large or overinflated
- Bouncing can be distracting for those on the other end of a video conference
The verdict:
The jury is still out on this one, but it’s definitely worth a trial run, especially for those who practice poor posture.
