Bundchen is the latest to sign on to Under Armour's multi-million dollar women's campaign, which focuses on empowerment of health conscious women with the slogan "I will what I want."
The first advertisement featured ballerina Misty Copeland dancing to a young girl's voice reading a rejection letter to a ballet academy.
In Bundchen's commercial, she kicks a punching bag as words insulting her scrawl across the walls of the room.
"She's just a model" and "She's nothing special at all" appear as she pummels the bag. The comments come from social media users reacting to Under Armour signing her as a female athlete for the campaign.
"This incredibly inspirational initiative serves as a powerful reminder of all the amazing things women can do despite the pressures and criticisms we may encounter," Bundchen said in a statement. "Having the strength to tune out negativity and remain focused on what I want gives me the will and confidence to achieve my goals."
