The challenge

The Interval Short is built for versatility. Constructed with four-way stretch to ensure maximum range of motion and a cling-free, ultra-wicking shell for mobility, the Interval Short was constructed to handle everything from HIIT to CrossFit to bootcamps. As a trainer at one of NYC’s toughest gyms, Zack is working on crafting and perfecting workouts that push people to their limits. Whether he’s leading HIIT movements on the turf or grinding out a new PR, he needs gear that can handle any type of movement as well as he can.
