Gisele Bundchen's new video advertisement for Under Armour has been released. The 1-minute clip released on Thursday, September 4 sees a fierce side of the Brazilian supermodel, kicking and punching a heavy bag as she tries to fight negativity.

Some comments such as, "Stick to modeling sweetie," "She's nothing special at all," and "She's old," flash on the wall around Bundchen as she shows off her athletic skills. In the end of the video, another comment which reads "She's a mother and an inspiration" and more flood the screen. The clip ends with the campaign's slogan, "I will what I want."

"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."

Earlier this week, ESPN reported that Bundchen and the sports apparel company had signed a multi-year deal which financial terms were undisclosed. She joined her husband Tom Brady who inked a deal to endorse their products a few years ago.
