@gently I still have my SandDune Stepper but I kind of forgot about it so thanks for the reminder. I set it aside when I had a knee replacement a few years ago and started using my FreeStep Elliptical Cross Trainer which is similar to a recumbent exercise bike for arms and legs. I do need to get that out and start using it as it is good for balance and strengthening the legs and feet - https://www.sanddunestepper.com/what-is-the-sanddune-stepper/.
