I already have a standing desk. But I still find myself tied to the desk for hours. My one thing is to set a timer and walk around the my work complex every hour.

I will take the clean laundry off the ping pong table and start playing again. On the days when no one is around to play, I'll go for a walk in my neighborhood.

I teach, so on my plan I'm going to leave my classroom and walk around the school at least once. I will try to work up to more times.

I hope it's okay to add on to something I'm already doing, since I have been trying to get more active. In March I joined the MFP group Leslie Sansone Walk at Home, and I started with 1 mile at a time, and got up to 2 miles 6 days a week, 2 weeks ago. (Yesterday I managed 3 miles.) My goal for May was 40 miles, because I wanted to add in other forms of exercising.

I am thinking of somehow adding in a 3rd mile, doing spurts or short walks throughout the day, in addition to the 2 miles. It can be another Leslie routine, a walk outside, or laps down in the underground parking garage between laundry loads. (I live in an apt building.) The 2 miles is before supper, so this other will be earlier in the day.
I have pedometer/ watch, which, if accurate, I need more strides to make a mile than most people. I tend to wear it only for exercising, but I am going to work on wearing it all day, and attaining 5000 steps daily this week, increasing that a bit each week.

I will do gardening on sunny days and de-cluttering on rainy days, for a minimum of 1 hour every day.

My one thing will be taking a walk if I have a afternoon slump instead of a nap. Or before a nap if I really need the sleep.

The Fitbit dashboard now has the hourly active minutes. I set mine from 6am to 8pm and I am going to get at least 250 steps in each of those hours. Doesn't sound like much but for someone tied to a desk 7.5 hours a day, it takes both awareness and commitment.

I have my fitbtit set to buzz every hour during work day to remind me to get up and walk my office floor which is a city block. My "one thing" has two parts. First part is to actually do it instead of turning fitbit off. Second part is to have it buzz every day instead of just work days.

I will increase the distance me and the dog walks every day.

I will walk around the cul-de-sac during commercials in the evening. This is a good starting place as most evenings once we get home there is little movement. I need to figure out how to move more at work. Our office is very small and the restroom is a whole 15 steps from where I sit.

I'm going to tidy my kitchen before i make my cup of tea after dinner, and I'm going to put the washing away instead of letting it pile up in the bedroom. (yes I know that's 2!) Tidier house and happier/healthier me. Win win.
