The medium Mini Stability Ball^™ will have a big impact on your workout and posture.

Use it during your workouts to create instability in your stabilizer muscles to sculpt a lean and toned body. Or use it after a long day of sitting for targeted self-massage, stretching and stimulating your connective tissue, ligaments, blood vessels, and fascia. Easily adjust the firmness and pressure of your ball by inflating or deflating the air inside.
