I'm very unfit, whenever I increase my activity levels I'm exhausted for a day or two. Is this normal?
I have two long term health conditions and struggling to know what's normal and what's part of my conditions so I don't know whether to gently push myself (try to get fit incrementally) or accept limits. My lack of fitness is because my health got much worse in the last few years, it's now improving so I'd like to start getting regular exercise - starting gentle and hope to maintain moderate weekly exercise.
I just feel so lost about it.
