Awesome Stability Ball! Review by Sean
I ended up swapping out my office chair for this ball, and absolutely love it. Now, for 8+ hours every day I can feel my core getting stronger. I can also do some very light ab exercises with it as I'm working. It's a great way to start losing some of that unwanted belly fat. Overall I'm extremely pleased with it!
