Mårten Boström out of Finland just invented a crazy WOD involving an all-out 400m sprint up a flight of 426 stairs. Not only that, but he finished it off in just 64 seconds! We can’t even make it around a flat 400m track in that kind of time. Check out the video and see if you’d try this one.
Dammmm thats some decent stairs in Helsinki Finland, I'll be done at halfway lol…Mårten Boström doing some real life Temple Run… #gamechangerDJ Reminise
