Nina Warrior Training Course ~Northvale, New Jersey~

DEAL: VIATOR: 14-Day Classic Japan Tour: Nikko, Hakone, Takayama, Hiroshima, and Kyoto from Tokyo

A Ninja-Warrior course filled with warped walls, an unstable bridge, and a salmon ladder forces competitors to hone both athleticism and brute strength, while 2,000 square feet of dedicated parkour space teaches the finer points of vaulting over obstacles and careening off parked ice-cream trucks.
