Because I have ankle arthritis “I have of late, forgone all custom of exercises”, as Hamlet says. But this is a bad habit and I realised my circulation was suffering.
So I searched online for exercises that could be done sitting or with the support of a chair back. There are a lot of good videos and for about three weeks now I’ve been doing some of the exercises.
And it’s had an effect! I can now stand on tiptoe, without the support of a chair back. Not very high or for very long, but I can do it. I couldn’t before. One tall step.
