This ball is a peanut-shaped fitness ball that offers a more stable base for balance and strengthening or it can be used vigorously to challenge postural reflexes and work the abdominal muscles. A critical tool in every therapy and fitness facility, this ball offers greater stability by limiting movement to forward and backward. The unique peanut shape allows a therapist and patient to share ball, until the patient has the confidence to work alone. Used by physical therapists worldwide, the ball offers stability and treatment options for more physically challenged patients. It’s unique shape allows a therapist to work on activities that otherwise may be somewhat risky on a traditional therapy ball. Additionally, it offers the individual exerciser the opportunity to exercise on the ball without the fear of rolling off to the side, since it provides lateral stability and is more stable than traditional round balls due to the fact that it will roll in one direction only. The “saddle-like” seat provides stability, comfort and confidence so clients of every age and nearly every diagnosis may participate in ball therapy. It is light weight, durable (weight tested to 660 pounds) and constructed of PVC free strong material.
