My weight

Since I decided to participate in the mayor's challenge, I've gotten lots of encouragement from my co-workers, friends and family.

But many have also questioned whether I need to lose 10 pounds.

That's always a nice thing to hear and maybe they're just being polite.

So here are the numbers: I'm 5'5". When I was weighed last week at my doctor's office, I was 150 pounds.

That means my BMI is 25. A BMI of 25 and over is considered overweight. I'm just on the edge, so I'm not under any delusion that I'm seriously overweight.

For the past couple of years, I've started eating much better, but I've hardly gotten anywhere close to the amount of exercise that I should. It's an unhealthy pattern that I've tried with little success to break.

I'm hoping this challenge will kick-start some good workout habits. It may also make me feel I'm finally getting my money's worth from my gym membership.
