These devices are popping up everywhere, and you may have even seen them at your workplace. Swiss Balls (sometimes just called exercise balls, or posture balls) are simple inflatable, exercise balls, that force your body to retain proper posture while sitting. They train the body to use proper spine alignment and balance while sitting. Their purpose is to reteach the body how to use a natural and correct posture. Many people also find that the ball kind of forces you to exercise, very minimally, but just enough to burn calories and strengthen your core muscles. Another perk is that these balls are relatively cheap and can be found pretty much anywhere; they can be kind of fun to sit on compared to your everyday office chair.
