The Summer Olympic Games are several months away, but the world’s greatest athletes have been training for their time in the spotlight for years.
Under Armour’s new ad campaign focuses on the training that Olympians put each day, and is encouraging other athletes to dig deeper.
The latest ad features Michael Phelps, 30, as he prepares for his fifth and final Olympic Games.
Phelps is the most decorated Olympian of all time with 22 medals in three Olympics.
Under Armour surprised Phelps and his fiancée by giving them a sneak peek of the ad before it was released to the public.
“That commercial shows a lot of amazing things about me that probably the world has never seen,” Phelps said.
In December, Phelps said this would be his last Olympic Games.
