FitBall® Seating Disc

Regular seat cushions don't let you strengthen core muscles, exercise your legs, or improve balance and coordination like the FitBall Seating Disc does. The 15" diameter inflatable disc has a dome shaped top that mimics the resistant conditions of a regular FitBall. You can increase of decrease the inflation to vary the challenge, or use the Seating Disc on the floor for tension relieving stretch exercises.

ANONYMOUS - Purchased FitBall® Seating Disc

I have been using the FitBall Seating disc for a few days now while at my desk job. I can't stop moving and wiggling. It is far superior to just sitting on my chair. I can already feel muscles in my back that were neglected. Now we'll see if my core abdominal muscles show any results.
