I tried Throwback Fitness, the playground-inspired workout studio that's like summer camp for adults

For millennial professionals and their colleagues, these trendy workouts are a healthy alternative to the afterwork happy hour or early breakfast meeting.

Dedicated to team fitness and re-imagined old-school recess games, Throwback Fitness is the newest addition to the scene.

Co-founders Ryan Wilke and Brian Gallagher left their desk jobs at an investment bank to open Throwback and teach three classes that mix full-body movements with competitive "playground" games.

Recently, I checked out their 45-minute Throwback class, where I rowed on an ergometer machine, threw Teenage Mutant Ninja Turtle balls into a net, and listened to a lot of music from the early aughts.
