Theraband 23030 Exercise and Stability Ball for Improved Posture, Balance, Core Fitness, Coordination and Rehab, Green, 65cm Diameter

It’s very sturdy and well made! Better material than the other balls I have!

I purchased this therapy ball after having had treatment for a lower back issue. This brand was being used at my therapy center. There are various sizes offered based on your height. It appears to be very well made and should last for many years.

I really like this exercise ball, but the manual inflator I bought at the same time was not great. I wound up using a bicycle pump and that worked great with no issues at all. The ball holds air pressure well, no leaks noticed, and performs very well in use. Good product.

Following previous reviews, I purchased a ball one size larger than was recommended by manufacturer. Was able to inflat to full 65 cm, but only using a air compressor--a simple hand pump took it to only about the size of a basket ball. Once it was fully inflated, it was hard as a rock and too big. So, I have deflated it to my recommended 55 cm size. It is still firm, but not rock hard. It's much firmer than my cushy Gaiam ball, but I think more durable too.

Super challenging to inflate—I had to do it in stages over a few days, allowing it to rest/stretch in between before it would accept more air. Now that it is inflated, it seems very strong and will support heavy person.

I finally found the right ball. It was recommended by the PT I have been working with. I used to love the balls at the gym I belonged to, but I hadn't been able to find the right quality until this one. Most I tried were just too soft, so that when you sat on them, they sank way down, regardless of how full you pumped them. I am able to do planks on this one, situps, and leaning back to stretch my back when I finish working out.

I've used Thera-Band balls at the place where I got physical therapy and I know they are great quality. The issue I had was that the ball I received did not come with an adapter that would allow me to inflate it with a bicycle pump, nor did it come with a plug. So basically it was unusable, as you can't inflate it without a plug to stop the air from exiting once it's inflated. Also, if you don't get an adapter for a bicycle pump, you will need some sort of pump that can fit into the hole of this ball to inflate it. As much as I love the brand, I would recommend a different ball that comes as a kit with a hand pump, plug, etc. I ended up getting a GAIAM ball and have been very pleased.

The material is thick and substantial. It is a bit difficult to inflate with the supplied nozzle, but with an air compressor attached it went well enough. Once the plug is installed getting it out with the included plastic device is difficult. It seems like the device to pull the pin free will break, but it hasn’t. Might be better if it was made of metal. Overall very happy.
