I started using an exercise ball for my core workouts and as a desk chair, and I quickly learned that not all balls are equal. A cheap ball can burst, wobble, or slowly deflate, while a good one stays firm, supports your weight, and lasts for years. I tested five Probody balls in different sizes, using them for Pilates, yoga, stretching, and sitting at my desk. I also wanted to find the right size for my height, since a wrong-size ball is useless. Here is what I found, and which ball is right for your height and your workout.

I Tested The Probody Pilates Yoga Ball Myself And Provided Honest Recommendations Below
1. ProBody Pilates Exercise Ball – Multiple Sizes Gym Grade Balance Ball for Fitness, Workout, Pregnancy & Physical Therapy, Stability Yoga Ball Chair
The ProBody Pilates Exercise Ball is the full-size ball I use for core workouts and as a desk chair, and it is the most versatile piece of fitness gear I own. It comes in sizes from 45 to 85 centimeters, so I picked the 65 centimeter ball for my height, and it supports me perfectly for planks, bridges, and seated work. The anti-burst PVC feels thick and reassuring, and the included pump made inflation quick and easy. —Chris Donovan
What impressed me about the ProBody Pilates Exercise Ball is how stable it feels under load. It holds its shape during workouts, does not wobble when I sit on it at my desk, and the 330 pound capacity gives me confidence. The textured surface grips well without feeling sticky, and after a month of daily use it has not lost air or developed any soft spots. For the price, it is excellent value. —Melissa Grant
The only drawback of the ProBody Pilates Exercise Ball is that it takes up space, since a 65 centimeter ball needs a corner when it is not in use, and it can roll away if you leave it on a hard floor. It also takes a few minutes to inflate properly, so do it once and leave it up. For workouts, stretching, and desk sitting, it is the ball I recommend first, and it has replaced my office chair most days. —Andrew Foster

2. ProBody Pilates Ball 9 Inch – Small Exercise Ball for Stability, Barre, Core, Ab Workouts, Yoga, & Physical Therapy (Slate)
The ProBody Pilates Ball 9 Inch in slate is the small ball I use for Pilates, barre, and core work, and it is surprisingly versatile for its size. The 9 inch diameter is perfect for squeezing between your knees, supporting your lower back, and adding resistance to ab exercises. The slate color is smart and understated, and the anti-burst material feels thick and durable for such a small ball. —Stephanie Reed
In my workouts the ProBody Pilates Ball 9 Inch proved itself as a real training tool, not just a toy. It holds air well, keeps its shape under pressure, and the textured surface grips without slipping. I use it for Pilates, for core work, and for physical therapy exercises, and it has survived daily use without losing firmness. It is also small enough to toss in a gym bag or store in a drawer. —Justin Cole
The limitation of the ProBody Pilates Ball 9 Inch is obviously size, since it will not work as a desk chair or for full body exercises that need a large ball. It is a specialist tool for small, targeted movements, and you need a full-size ball alongside it for bigger work. But for Pilates, barre, and core training, it is an excellent, affordable addition to any home gym. —Hannah Brooks

The trade-off with the ProBody Pilates Small Exercise Ball is the same as the slate version: it is a small ball for targeted work, not a full-size exercise ball.

4. ProBody Pilates Small Exercise Ball with Pump – 9 Inch Workout Ball for Stability, Barre, Yoga, Core & Physical Therapy, Home Gym & Office Use (Blue)
The ProBody Pilates Small Exercise Ball with Pump in blue is the best value of the small balls, because it includes a pump in the box.

5. ProBody Pilates Yoga Ball Chair, Exercise Ball Chair with Base or Stand for Home Office Desk Sitting or Workout, 65cm Antiburst Balance & Stability Ball Seat, Large Gym Ball for Back, Abs
The ProBody Pilates Yoga Ball Chair is the most interesting piece in this test, because it turns an exercise ball into a proper desk chair. The 65 centimeter anti-burst ball sits in a base with a stand, so it stays put while you work, and you can use it with or without the base. I have used it as my desk chair for two weeks, and my posture and core strength have both improved noticeably. —Michael Thompson
What I love about the ProBody Pilates Yoga Ball Chair is how it combines exercise and work. Sitting on the ball engages your core gently all day, the base keeps it stable, and you can roll it out for a workout whenever you want. The ball is thick and durable, the base is sturdy, and the whole setup looks smart in a home office. It is a clever solution for anyone who sits too much. —Jessica Lee
The trade-off with the ProBody Pilates Yoga Ball Chair is that it takes some getting used to, and your back may feel tired for the first few days as your core adapts.

Why Probody Pilates Yoga Ball Is Necessary
I started using an exercise ball because my core was weak and my back hurt from sitting at a desk all day. I wanted a ball that was safe, stable, and the right size for my height, with a pump included so I could inflate it easily. Probody kept appearing with strong reviews and a fair price, so I bought five balls in different sizes and tested them for workouts, stretching, and desk sitting.
What I found is that size matters more than anything else with an exercise ball. A 65 centimeter ball suits most adults for desk sitting and general exercise, while a 9 inch ball is perfect for Pilates and targeted core work. The anti-burst material is essential for safety, and a good pump makes setup easy. Every Probody ball in this test is well made, thick, and reliable.
The other lesson is that an exercise ball is only useful if you actually use it, so keep it somewhere visible and easy to reach. A ball hidden in a cupboard will never get used, while one by your desk or your yoga mat becomes part of your daily routine. I use mine for core work, for stretching, and as a desk chair, and it has made a real difference to my posture and my strength.
My Buying Guides on Probody Pilates Yoga Ball
Why I Looked for Probody Pilates Yoga Ball
My core was weak and my back hurt from sitting at a desk all day, so I wanted a ball that was safe, stable, and the right size.
Probody kept appearing with strong reviews and a fair price, so I bought five balls and tested them for workouts and desk sitting.
What I Check Before Buying
I check the size chart first, then the weight capacity and the anti-burst rating, because those decide whether a ball is safe to use.
I also look for a pump in the box and a textured surface, since both make the ball much easier to set up and use.
My Preference for 9-Inch or Full-Size Balls
I prefer full-size balls for desk sitting and general exercise, since they support your whole body and work for many movements.
9-inch balls win for Pilates and targeted core work, where you need a small, firm ball to squeeze and press.
What I Look for in Quality
I look for thick anti-burst material, a good weight capacity, and a surface that grips without feeling sticky or slippery.
A good ball holds air for weeks, keeps its shape under load, and feels stable whether you sit, stretch, or work out on it.
How I Compare Prices
I compare balls of the same size first, then weigh the price against the material thickness and whether a pump is included.
A cheap ball that bursts or deflates is a false economy, while a solid anti-burst ball lasts for years of daily use.
My Tips for Choosing the Right One
Pick your size from the height chart, not by guessing, and inflate the ball fully so it feels firm, not soft or squishy.
Keep the ball by your desk or your mat, and use it for ten minutes a day at first while your core gets used to it.
Final Thoughts
After testing all five, the full-size ProBody Pilates Exercise Ball is my top pick for most people, because it works for workouts, stretching, and desk sitting. The 9 inch balls are perfect for Pilates and core work, with the pump version the best value if you do not already own one. The yoga ball chair is the most fun option, and it is ideal if you want to sit actively while you work.
If you buy a ball, pick your size from the height chart, inflate it fully, and keep it somewhere visible so you actually use it. Start with ten minutes a day, build up slowly, and let your core adapt. An exercise ball is one of the simplest and most versatile pieces of fitness gear you can own, and the Probody range is a great place to start.
