Went on my second run today, and this time ran four times and a little bit of another. I was out of breath, but did not have the same tightness in my chest as I did the first time I ran.
For the meantime, my plan is to probably repeat week one, just until I'm confident and can run for the whole 60 seconds seven times. Right now that feels hard, but not unattainable. I also took water with me this time, which helped, I think?
However I do still have a slight ache in my calves, from my last run? Is it normal to still feel that sort of dull ache in your muscles over 24 hours later?? (Note I barely exercised before this, and am very much attached to the couch.) Weirdly I feel better after going on my walk/run, in terms of the muscles and in my mood, which is really nice!
