The TheraBand Mini Ball is a 9-inch inflatable PVC ball used in physiotherapy and home exercise programs to add instability and tactile feedback to core, shoulder, and postural exercises. It can be positioned between the body and the floor or wall to increase the challenge of standard rehab movements. For climbers, it is particularly useful for shoulder stabilization drills, scapular control exercises, and core work where a small, soft surface is needed to cue proper muscle activation. No pump required — it inflates by breath using the included tube.
Mini Ball
Description
How is the mini ball different from a full-size stability ball?
The mini ball is designed for targeted exercises where you need a small, soft, compressible surface rather than a full seating or balancing platform. It is placed between the body and a surface — such as between the lower back and the floor, or between the hand and a wall — to add instability or tactile feedback to specific movements.
How can climbers use a mini ball in rehab?
Common applications include wall push-up progressions with the ball under the hand for shoulder stabilization, placing it under the lumbar spine during core exercises to increase range of motion, and using it between the knees during bridge exercises to cue hip and core activation.
Does it come with instructions?
Yes. The mini ball includes an instruction booklet with exercises covering the abdomen, upper body, lower body, and shoulder rehabilitation — a useful starting point if you are working through a home program.
