Workout while sitting
The Stability Ball is a great for improving your posture and strengthening your core and back at home or office. Through active sitting, challenge your core to support the spine and maintain balance on the ball. Learn about how to choose the right height in the FAQ tab.Add dynamic challenge to your workouts
The Stability Ball adds challenge to your workouts by providing a plane of instability that forces joints and muscles to react to maintain your balance. Workout the lower body with exercises like Wall Squats, the upper body in Balance Planks, and the Core with V-Sit Ups. Find great workouts here. Stretch out and improve flexibility
The Stability Ball is a great tool for a post-workout stretch or any time tension has you stiff and sore. Stretching increases your flexibility and range of motion, and also relieves the lactic acid that builds up in your muscles during your workouts.

Back pain is often the result of having weak stabilizing muscles supporting your joints. Without muscular support, your joints simply collapse. The Stability Ball is effective in rehabilitating your back because it strengthens and develops the core muscles that help to stabilize the spine. Find our Secret to a Strong Back here.
How do I choose the correct size ball?
A Stability Ball when sized properly makes for an active chair when sitting at a desk, keeping your core engaged, preventing and rehabilitating back injuries while improving posture. The general guidelines in choosing the correct ball size are:
Deflate the ball until your body is aligned so that when sitting your knees are at a right angle and your thighs parallel to the ground. If you are close to a cut-off point, opt for the larger size and deflate accordingly (this will also lead to a more comfortable chair).How do I inflate my ball?
- Remove plug from ball with double pronged lifter
- Attach plastic needle to pump (on some pumps the needle is stored in the handle; remove small plug on end of plunger to locate storage compartment)
- Insert needle, inflate to desired firmness and replace plug
Note, for full inflation inflate ball, allow to rest for 2 days, and then complete inflation to ensure that ball is the proper size.
