These are the best I have found over the years. I have three of these that are 20 years old. They get used every day by clients. They are still round, hold their air well, and a solid purchase.
They may be a bit more then people would expect, but Many of my clients have them and love them.
This is the Fitterfirst Dura ball Pro:
These are what I use. They are great and they last for ever.
I only had one client pop hers because she left it sitting next to the fireplace.
You need to get the right size:
People that are 5 feet 10 inches or taller should get the 75cm/30 inches
People that are 5 feet 5 inches to 5 feet 10 inches should get the 65cm/25 inchs
People that are 5 feet 4 inches and below should get the 55cm/21 inches
Here is an Amazon link for you to buy one for yourself.
