Introducing: the 2V2 workout

“Small wins lead to positive habits,” says Brian Mazza, New York City-based co-creator of Four30 at PROJECT by Equinox. For him, those victories happen every time he logs a 2V2 workout, which he devised with Four30 business partner Rob Pannell, professional lacrosse player and entrepreneur.

Here’s how it works: In 2V2, two sets of partners face off to complete a prescribed routine with the goal of finishing before their opponents do. While one person on each team works, the other rests; once that partner is totally breathless, the other taps in. The pairs can only move from one exercise to the next once they’ve completed it in full.
