I’m able to do a limited range of exercises indoors (rowing machine, dumb turbo, weights, core stuff). It’s the outdoors coupled with the innate joy of running dynamics. I went for a 13k walk that included some greenery, and my spirits soared up until the point where my Achilles started hurting.
That is a strong statement. I would very much like to say the same in mine.
Is it exercise or exercise outside that's going to help?
