The document describes a partnership between Reebok and CrossFit to hold pop-up gym experiences in major US cities in May 2017 called Cal4Cal. For every calorie burned by participants, Reebok and CrossFit will donate the same number of calories to Feeding America. Calories lost and donated will be tracked live so people can see the impact. Participants get a free workout, Cal4Cal merchandise, gym and Reebok discounts, and will help people in need through their workouts. The goal is to show fitness is about more than just exercise by bringing the community together and fundraising through an interactive event.
