Review on Extra Thick Exercise Ball For Workout Fitness Balance - Gruper Yoga Ball In 45-75Cm - Anti Burst Yoga Chair For Home And Office With Hand Pump & Workout Guide Access Included by Terry Gernes

The material is very resistant and does really offer you a great friction with the floor helping stability, however, the 22 inches is super small. I followed the chart saying that for 5’3 high people the 22 inches (55mm) was the perfect size but is definitely way too small. In the picture I added another ball I have that is 85mm, but that was way to big. I believe the perfect size for everyone (no matter your height) is 75mm which is the 30 inches.
