Hi eve
I have osteoarthritis and my right knee is very affected , even walking is difficult as I have pain , stiffness and instability due to bone on bone . I am advised to either swim as it isn’t as bad a walking as the water supports the joints and it’s very important to try and improve the leg muscles to stabilise the joints . I am 62 , I do floor exercises, and walk most days to stay as fit as possible. If you have the start of arthritis it’s important to get checked out as jogging will accelerate the condition as it’s high impact . Gentle regular exercises i think are better overall for over 60,s and being kind to our bodies . I used to run , cycle , horse ride , and go to high impact aerobics which I feel has accelerated the damage . I don’t let the condition define me , I look forward to what I can do rather than what I can’t , and stay mindful ? about it all ! ?
