Cross legged
I sit at my desk nearly all day long but I don't want to be completely sedentary, so I'm experimenting with a balance ball as a desk chair. 4,567 bounces into my first day "on the ball", I am enjoying the novelty.
As you can see in the photo, I've figured out how to sit on it cross legged. Although I haven't mastered it yet, I can type from this position. MJ says this is "a one way street to a bump on the head," but I think it's more likely a fast train to backache.
Still, a backache is better than an expanding bottom.
Does it help the bottom? You may have a convert.
I found my ball from a box yesterday. I must try this, too.
My back ached a little on the first day when I realized it was because I wasn't slouching!
You should be fine by day 3.
i used to sit on a ball at work and loved it! Unfortunately, something in our office must not have liked it because it was punctured and developed a slow leak. At that point it became great for my arms because i had to pump it up every morning, but then i just had to make it go away. It should help you strengthen your core muscles as well. Hope it works out!
