With the health of today's youth a national priority, professionals need tools for accurately assessing activity patterns and motivating behavior change. Fitness technology may be a promising tool for promoting positive behavior change. The afterschool program WeCook: Fun with Food and Fitness focused on improving food preparation skills, nutrition knowledge, and physical activity levels of youths. As part of the program assessment, each participant wore a Fitbit near the beginning and end of the program. Fitabase, an online research platform, was used for aggregating and analyzing data. We discuss a model for incorporating these technologies.
