Michelob Ultra 'Cheers' fitness in Super Bowl ad

Sweating takes center stage in low-calorie brew ad set to classic TV show theme.

Michelob Ultra is returning to the Super Bowl this year with another fitness-themed commercial. Last year, the brand ran an ad that focused on the breath of strenuous workouts. This year, scenes of people exercising--cycling, boxing, running—are set to the theme song from "Cheers" and culminate with shots of post-work out beers with friends.
