The challenge

The Interval Short is built for versatility. Constructed with a four-way stretch to ensure long-term durability and a no-pinch, no-bunch waistband for a secure fit, the Interval Short was created to be the ultimate workout companion -- ready to handle everything from HIIT sessions to metcons, and everything in between. A health food chef and workout fanatic, Seamus needs a functional and comfortable short that performs day after day, so we had him put the Interval Short to the test in a workout designed to test its limits.
