After a workout, I have back/hip pain and all the flexor exercises don't quite reach the target. These were recommended to me by a Physical Therapist and they are incredible! The balls are soft enough to not feel like rocks under your back, but hard enough to reach the deeper tissue. I use a yoga mat as my base, and then lie on top of the balls. The yoga mat offers another layer of bounce/give. I highly recommend them!

I'm an occupational therapist and have been using this item almost daily with clients for upper extremity mobility exercises and weight bearing. It's sturdy and easy to clean.

Have a neck problem and can adjust to the firmness I need.

Perfect and easy to store in dance bag!

Got these for Pilates and self massage. Perfect size and quality material. Would purchase again.

Son comodas a la piel. No resbaladizas. Muy buena textura!!

Did the job!

My physical therapist recommended these Franklin balls to me. They help better than using tennis balls for doing fascia releases using the wall. They have a bit of give to them, but are still supportive enough to allow good movement.

I received this mini ball as a gift, and I have been using it for fitness, mainly with the workout Tracey Mallett-Pilates Super Sculpt. I also purchased a similar ball, 9" Body Back Ball & Pump, so I will be comparing the two balls in this review.The Overball that I have looks just like the blue one pictured above. As you can see, the surface of the ball is covered with slightly raised dots; this improves the ball's gripping surface, making it easy for the Overball to stay in place under your back, behind your knee, etc. The Overball comes with a small, short plastic straw to inflate it and a small plastic pin to use once the ball is inflated. The ball fills up easily enough with the straw; I found that the inflation process took only a minute or so. The problem I had was when I went to insert the pin. The Overball does not retain air very well at all, so every time I tried to insert the pin, the ball deflated almost completely in the brief moments it took me to get the pin in place. I had to repeat the process several times; finally, I inflated the Overball way beyond the point where I wanted it to be, put the pin in as quickly as I could, and was satisfied with the results. I did not have this same problem when inflating my Body Back Ball (which comes with its own nice little hand pump); that ball definitely seemed to hold the air better to allow for pin placement.In terms of actual performance, I have had no problems with the Overball. It does seem a little squishier than my Body Back Ball, but that might be because of the inflation issues--if you are looking for a firm ball, this is definitely NOT the right choice! But for use with Pilates and other core workouts, where a slightly deflated ball is desirable, the Overball works quite well, and I would recommend it overall.

When I received this ball in the mail it had a hole in it. I called the company and they said to just throw it away and they'll send me another one free of charge. That's great customer service! As far as results it's still too soon to tell, but my jeans are fitting better in the tummy area.

I have used this in my exercise class and now using it at home when I do not get to class. It is great for thigh exercise and intensifies ab workouts while keeping good form.
