If you are doing station work, have one of your stations be the Fat Cat 7 Minute Workout. Position a Chromebook at the station and students simply start the workout. http://fatcatworkout.com/?cws#/ With breaks, it takes 8 minutes to complete the workout. If you are only doing 4 minute stations, students could stay at this station for 2 rotations.

To add variety and challenge to this activity, have studens do each activity as a group (2-4). During the break, they must determine a way to do the next activity together.
