Not just your feet, your whole body was made for walking, but how much do we do? Not nearly enough. Last week we got some free stuff from Amazon. As a reward - depending on how you look at it - for being one of Amazon's top 1000 reviewers, I got invited to apply for free stuff as long as I review it. It's got a downside. If you write something bad, its publisher will send out an army of web monkeys to give you an "unhelpful" vote but the ASA are looking into that so I'll leave it for now...

So a big parcel turned up and beneath all the cardboard were a set of scales, a blood pressure monitor and a pedometer, with instructions to download the software from MiBody360.com. So we did. I've not had a set of scales for, well, not ever come to think of it. So Mr. R. and I set off on our quest so see if we can fit into our smallest clothes. We don't want to be as thin as when we were kids, just as thin as when we met. Mr. R. is putting his Paul Smith shirt buttons under a great strain at the moment.

I got first dibs on the pedometer. We're supposed to do 10,000 steps a day to stay fit. Days one and two I didn't leave the house and did around 1,100. 11%. Not good enough. Day three, I walked to the Post Office instead of driving and taught a yoga class. Up to 6,000, Day four, I taught another yoga class, walked to the tube station, walked from Holborn to Oxford Circus, up and down Regent Street, and home from the tube again. 11,000 steps. That's all it takes to go from slob to fit.

Today I've yet to leave the house and I've only done 547. 123 of those were from last night as it resets itself as midnight, assuming that you've gone to bed by then. (Daft machine.)

So this week, I recommend that you get out and about a bit. Get walking. Just knock one stop off the tube or the bus journey and you'll add in a thousand steps. If you drive, don't park as close as you can to where you're going. And I'm off to the Post Office to keep the calories from accumulating, the heart ticking over nicely and to post a couple of parcels while I'm at it.
