I Will.', which simultaneously highlights Under Armour's core commitment to combine training and provides an intimate look at some of our most dynamic young athletes. Consistent with Under Armour's mission to make all athletes better, these individuals share an incredible passion to be the best at their sport," said Steve Battista, Under Armour Senior Vice President, Brand. "This is one of our most ambitious efforts to elevate the heritage of our training platform, and we feel that Michael Phelps - a true global icon - is an ideal ambassador for the 'Protect This House. I Will.' message."

"I'm looking forward to a great relationship with Under Armour," said Phelps. "As a Baltimore native, I have always been a fan of the Brand and admired their success. Given our mutual commitment to training, this is a natural partnership, and 'Protect This House. I Will' is a perfect way to kick things off."
