@Lottie how do I know that tho without trying them? I don’t want to order the wrong one 😂
i have a 65 inch one (im pretty sure) if ur going to watch videos and follow along they usually in the beginning tell u what ball and how big the one they’re using is! good luck 🤍
Pretty sure it’s done based on height but worst case you can order different sizes and send one back?
One that means your knees are still above your pelvis when you sit on it.
