Droga5 New York injects new life into the adage, practice makes perfect, for Under Armour.

American Ballet Theater ballerina, Misty Copeland; NBA Golden State Warriors guard, Stephen Curry and PGA Masters gold champion, Jordan Spieth, multiply to the rhythmic beat of a choral chant counting training reps, to become armies in perfect formations.

The message is practice makes perfect, expressed in the Droga5 ad’s tagline for sports brand, Under Armour, as, You are the sum of all your training.

Felix Richter, creative director at Under Armour’s agency, Droga5 New York, explained, “We want people to feel that when they train they don’t do something repetitive over and over to no end. Every time you train, you add another soldier to the army. And when it comes to game day, all this force is with you.”

The ad is part of Droga5’s Rule Yourself campaign, Rule Yourself, the includes the lead ad (60 seconds) plus individual ads that highlight the behind-the-scenes training that goes into the world-class performances of the brand’s four ambassadors.

Under Armour’s ambassadors (New England Patriots quarterback, Tom Brady, is the fourth) have been doing their bit for the brand all year.

Jordan Spieth won the Masters in April and the US Open in June. Stephen Curry was named the National Basketball Association’s most valuable player this year and led the Golden State Warriors to the league title. In June, Misty Copeland became the first African-American woman to be named a principal dancer in the 75-year history of the American Ballet Theater.

Brady is the black sheep. Which the brand is planning to use to its advantage. Brady led the Patriots to a fourth Super Bowl championship in February, but is now fighting a suspension as the star of a controversy called Deflategate, which has grown from accusations that New England Patriots tampered with footballs used in the American Football Conference Championship Game against the Indianapolis Colts on January 18 this year.

Brady’s 30-second ad is planned to run during the early part of the National Football League season in September.

The new campaign is based on the idea that athletes are the products of their training sessions, said Felix Richter, a creative director at Droga5, the agency behind the campaign.

“We want people to feel that when they train they don’t do something repetitive over and over to no end,” Richter said. “Every time you train, you add another soldier to the army. And when it comes to game day, all this force is with you.”

Adam Peake, executive vice president at Under Armour, added, “…we’re focused on the work ethic, the will to be the best, and that doesn’t stop.”
