Just completed my second run and I found it so much harder than the first outing! My muscles weren't aching before I started but they seemed to tire much more quickly this time? I also felt it in my abs. I didn't even realise your abs did any work when running!! Yes I'm a total exercise newbie 😄
Anyway I did manage the whole session and feel really pleased with myself but I can't imagine being able to increase my run time next week.
