When I saw the title on a different topic I thought it was referring to the exercise and see it was referring to diaper-like garment. But now that I mentioned it, what is the feeling of doing the exercise pullups or any type of non-equipment exercise on Shabbos?
Would it then require a doctor to prescribe doing the exercise if it’s refuah? I take refuah to mean a cure, but exercise is for good health, not to serve as a treatment for a medical condition. I can’t even imagine why it would be considered oneg Shabbos.
Something like walking can be done for exercise or for pleasure or both. Although usually the pace will define its intent, if someone is elderly, post surgery etc. what may seem leisurely can be pretty intense for their fitness level — especially if it’s a long walk. Even dancing can be both — but it’s usually not too much fun without music…
And exercise is used in physical therapy so it’s not necessarily just to maintain health.
