31 sets up/down the #archsteps grand staircase. Every 5 sets I rolled this very cool dice to see what exercise I would do. Fate would have it that it landed on a lot of jump exercises. It was fun. It was also nice and warm at 25 degrees outside. #stairninjaadventures #enduranceworkout #coldworkout #americanlungassociation #lungmissouri #lunchtimework #americanninjawarrior #ninjwarrior #steps #stairsworkout #arch_athletic #neverstopmoving #goodjourney @lungmissouri (at Gateway Arch, Jefferson National Expansion Memorial)
