Many of us tend to sit too much. Driving to work, sitting while at work, sitting while watching that favorite TV show, sitting while on Spark..
Ration your sit time by parking as far away from your work as you can & walking. Do the same when shopping. When you get home, unload groceries two bags at a time.
At work, when you are on a break or at lunch, climb the stairs & don't take the elevator. Instead of lifting you up, taking the elevator really takes your strength down.
that favorite TV show, stand & march in place. When entering information & answering Sparkmail or participating on one of your Spark teams, stop & walk around your house between every session - don't go from Spark team to Spark team, break it up.
The more you move, the healthier you'll be.
