Gisele and Jimmy Fallon on all fours?! Hello!

During a visit to The Tonight Show, the supermodel challenged host Jimmy Fallon to get on the floor, tighten his abs and assume the plank position -- and it's pretty impressive.

The leggy Brazilian, who is the new poster girl for Under Armour's new female friendly campaign, showed off her immense strength when she challenged the funny man to do some intense yoga moves.

Despite wearing a leather bodice, heels and trousers -- the mom of two shows off her fit form and her athletic prowess -- while Fallon flounders with the moves. Needless to say the powerhouse model schools the nerdy comedian in all things physical!

Other than her stop at The Tonight Show, Tom Brady's wife has been making headlines for her recent partnership with Under Armour, which is trying to branch out its brand to women.

The sportswear brand recently released a 60-second spot showing Gisele kickboxing while real-life Internet criticism is projected on both her and the walls. The whole thing is pretty powerful and we recommend a watch. We guess life can be hard for pretty girls too!
