I was kind of dreading it to be honest. I smoke, I'm overweight and it seemed very daunting. I was also feeling cold and well, like being a couch potato! I did my first session. The hardest part was the pain in my legs. I think, not sure, that I suffer with sciatica. Anyway, I did not run everytime during the 60 minute run, I just walked really fast. (Fast for me anyhow). The pain was stopping me, else I would have. Anyone else suffer pain? Anyway Im pleased. How was your first session?
