The School of Friendship finds itself in need of an instructor to get their new physical education and outdoor skills program off the ground. Twilight offers the position to Rainbow Dash. Who better to run the program than a natural athlete and Wonderbolt? Too bad Dash is already busy with her own classes and practice schedule. When asked if she has a suggestion in mind for the position, Rainbow Dash offers an unexpected name as an alternative.

On the morning of their first class, the students are understandably excited to find out which of their favorite professors was chosen to instruct them in the rigors of physical fitness and education. When the gym doors open, and their new instructor appears, it becomes immediately apparent their class will be anything but easy, or boring.
