Fitness is the 34th episode of BrainPOP. It aired on June 15, 1999.
Tim gets a letter about fitness. He has to go running, so he tells Moby to show the viewers a film. The next two minutes feature "Exercise, Fitness, And YOU!", a cheaply-made short film. However, Moby doesn't realize that Tim is doing fitness, too. At the end, a post-credits video shows Tim running.
