Merrithew Mini Stability Ball – Large (Orange)

I use this ball when I do the Mutu System exercises to correct diastasis recti. It's a good size for the in- between- knees squeezing I have to do, although I purposely did not fill it to capacity because this is how I use it most and I like it ever so slightly squishy. I like that I can use it the way I have been, or to stabilize my back if I want - its size is flexible. I did not have a difficult time filling it up, the straw might be a little fiddly, but I didn't find it frustrating. You do need a bicycle pump or something of the sort. Mine hasn't lost any air since I filled months ago. I think it's of good quality - I use mine several times a day and my child-hellions kick, throw, toss, stand on, and abuse it all the time. And can I say that it's cute? Because it is. I realize that doesn't matter to a lot of people, but my heart gives a happy sigh when things are cute. Very pleased.

This was super easy to inflate. I use it all of the time, it's excellent quality for the price and I'm able to use in a variety of ways to workout. A perfect additioin to my home gym collection!

Nice size ball for my Pilates practice.

This mini stability ball has been a solid addition to my workouts. It’s just the right size for core exercises, and it helps add extra challenge to simple moves like crunches or bridges. The material feels durable and holds air well without deflating quickly. It also has a slight grip to it, so it doesn’t slip around during use. I’ve used it for both strengthening and stretching, and it works well for balance training too. It’s lightweight and easy to inflate, making it simple to pack away or bring along to a class. Overall, it’s a versatile tool that makes home workouts more effective.

I like this for doing core workouts on the mats. It's not the thickest ever... but does the job holding up my 150 lb. while I'm rolling around and pressing on it.

I think others would prefer the larger blue ball but I liked the smaller one. The larger one is the 7.5. Bought at different times. I use these for doing body rolling. Softer than Yamuna balls, they are better for my body. They dont smell toxic and they are great for traveling. The blue ball is my most used ball. The other two larger ones and wonderfully large and so good for belly rolling. Very happy with balls

nice and enjoying

This is a review for 10in ball (lime color). It is true to the size. It is fine but loses air somewhat quicker than expected when unused. I use foot pump from air mattress to inflate it. Inflation is easy but during the time between removing the pump nozzle until the plug is inserted a lot of air is lost no matter how quick you are. Basically you need to overinflate to compensate for the loss. It should be constructed better to keep the air in better for a short time without a plug. Another issue is when you need to re-inflate it is really difficult to remove the plug. You will probably break your fingernails while trying (or have them separate from the fingers). I have another ball (22in) from a different brand and it comes with a plastic prying tool just for that. But this ball doesn't.
