I am 45, normal BMI but a bit flabby around the edges. I have never been fit and even as a school kid couldn't even manage 400 m and hated all sports. I was always the last to be picked for any team. Health reasons encouraged me to get fit and having a busy job and two young children it was difficult to know what exercise I could fit in. I had never previously considered running as I didn't think I would ever be able to do it. However after hearing about somebody else start this plan I thought I'd give it a go.
It's amazing!
I struggled running one minute in the first week and I've just completed my first 30 minute run managing 4.12 km. To say I'm chuffed is an understatement. An added bonus has been that from about week six I have noticed my shape changing and some of the flab disappearing. My husband even commented that I didn't look as silly as he thought I would when running! I don't particularly enjoy the running but I do enjoy the achievement.
So if you're thinking about starting the plan, go for it. If I can do it anyone can!
