Oh and I thought I'd mention that the first time I got on my exercise bike, I did 6 min and about 2kms and felt like I was going to have a heart attack. But I got better and faster as I kept doing it, and eventually, after 6 months, was riding 40kms each session. Exercising is a pain in the ass, but so rewarding if you stick at it.

I've just started exercising formally again after 18 months of just incidental exercise. I am feeling the pain of starting from scratch too, trust me. So curse and swear and hate it, but do it. I am exercising 30 mins Mon, Wed and Fridays, rain, hail, shine, sickness or just plain laziness. Walking, cycling, running. Whatever.

30 mins a week is just 90 mins in a week that consists of 10080 mins. Not much at all when you think of it.
