See Who Wins in This Plank-Off Between Gisele B¨¹ndchen and Jimmy Fallon

Last night| Under Armour spokeswoman Gisele B¨¹ndchen made it clear that she’s working with some serious strength on The Tonight Show. After Jimmy Fallon showed off an awesome Instagram photo of Gisele holding a headstand on the beach| she taught him a move a little more his speed: a one-minute plank pose. Once the two tried to set up the exercise with proper alignment (his backside was up in the air more than we’d recommend)| Gisele showed Jimmy some more challenging variations with a lifted leg and an added push-up. Watch to see for yourself| and try them at home!
