I exercise with a trainer doing boxing twice a week and have done for the last 2 months & some weight training but I'm really struggling with stairs still .
I have been diagnosed with long covid in early 2023 and went through periods of severe breathlessness but it seems to be getting a lot better
Can anyone suggest how I can train for larger flights of stairs ( 200 + stairs ) which I sometimes encounter on country walks / historic site tours
Weirdly I walk up the stairs in the tube station a couple of times a week and feel ok 🤷♀️
