Lights, lasers, treadmill, ACTION!!
Usher can't-can't-can't stop KILLING his live performances.
Da Bieb's mentor proved he still has the stamina of a teen by dancing (and sprinting) his way through
one two three songs on the American Music Awards stage!
Watch the man make his way through Numb, Climax, Can't Stop Won't Stop in the FIRST AMA performance of the night (above)!
Sure, he misses a few notes, but can you blame him?! He's running on a motherf*cking treadmill! GET OVER IT! :)
