Hi
I thought I was quite fit; twice a week at least doing HITT/boxercise/weights. Walk a lot. Active. i'm nearly 50.
The past couple of weeks I've done a new walk with my dog. There is a very steep hill as part of the walk. Not quite vertical, but quite fierce.
I am really strugglign with it. Out of breath after about 20 steps. HAve to pause etc.
It really worries me. I was a smoker for years back in the day. Am I worrying there is an issue, or would you expect breathlessness?
