I am 5'2," and this ball is too small for me to use the way I expected (core exercises). I went by the size guidelines for my height. I have tried a larger one before and prefer it. It is hard to inflate this ball firmly, and when I sit on it, my knees are way above my hips. Also, the pump comes apart easily, letting out the air when you try to inflate it.
- How accurate was the sizing? accurate
