If you are working with children to increase their activity levels or to reduce obesity, take the time to check out My Fitness Pal. This is a free, fun tool that calculates how many calories you burn doing many different tasks. You pick the activity, put in your weight and for how long you did the activity. It quickly calculates how many calories you burned. It includes so many different physical activities including Wii games, popular fitness programs and different types of yoga. Did you know that sitting down while ice fishing burns a few more calories than Wii bowling??? Check it out at MyFitnessPal.com.
Here is an idea ... start a contest among different classrooms or grade levels. Who can burn the most calories? The kids and teachers can keep track of all their activity and add up calories burned over a certain time period. At the end, the winning class can get a reward of bonus recess time.
