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 was wary about the ball being the right size and that the needle pump would actually fill the deflated concave looking ball. Much to my delight, it was able to fully inflate the ball to its advertised size! I can use it for my exercises now.

I needed a small ball for some of my exercises, and it's surprisingly hard to find one. This is not 4", it's smaller and fits easily into the palm of my hand, but it serves the purpose I needed it for. It does not blow up to a round ball, it's an odd shape, but again, it works for what I need it for. What I'm using it for: a cushion and resistance between ankles and feet to perform rehab exercises.

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.

Very disappointedDon't waste your money. The pin broke immediately & it cannot be inflated without it.

I enjoyed working out with it.

Excellent product to help in so many excercises

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.
