4 inch Therapy Ball for Release Hip Flexors, Pain Relief for Lower Back Thigh Muscles, Small Exercise Ball for Physical Therapy, Blue

Perfect size for my husband that is in physical therapy now after rotator cuff surgery. Just soft and grippy enough for him to maneuver with his at home exercises.

I received the box. Opened it and found that the needle required was not included in the box. So it's useless. Oops, it's in the handle of the pump!! My bad.

Excellent product to help in so many excercises

Ball is great--the pump is not. I'd purchased a larger version of this same ball several months ago and loved it. When this ball arrived the pump that came with it only worked for a couple of "puffs"....then it failed to push more air. I finally managed to inflate it by using the pump that came with the first ball.....and now that pump is also no longer working. Amazon's only options are to refund/return but not just replace the pump. So now I'm shopping for a good pump.....

Wife’s PT had her use a “cooch ball” for pelvic floor/tailbone tension release use. This is a great alternative as they are both 4in and can be inflated and deflated as needed for firmness. She says they feel identical, but this one is a fraction of the cost.

This is advertised as a 4" diameter hip flexor ball. If you inflate it enough to be as firm as a typical hip flexor ball (such as the plastic ones made by Aletha or the cork ones by Aquanimous), it is MUCH bigger than 4" in diameter. I should have paid attention to the main product photo. Look how big the ball is compared to the person's hand. There's no way that's a 4" ball...

Exactly as described.

Nice ball was too small.
