What is HYROX training at Hidden Gym?
Hidden Gym Allen runs a dedicated HYROX program 25 minutes north of downtown Dallas — coached classes on official BLK BOX competition equipment, periodized race-prep programming, and a training community, led by HYROX Director Shelly Reynolds, who has raced HYROX more than 16 times and serves as an official HYROX judge.
The Difference
What makes HYROX atHidden Gym different.
Teaching
The goal of our classes is not only to lead you through a killer HYROX workout but also to teach you technique. That makes you faster and minimizes injury risk by performing the movements correctly and safely.
Walk the Walk
Hidden Gym HYROX coaches are not just personal trainers teaching a HYROX class — you work with actual HYROX racers who practice what they preach.
Programming
We aren't just providing isolated workouts. All HYROX memberships include a comprehensive program to follow when you're not in class — strength training, running, and mobility, all easy to follow in the Hidden Gym training app.
Community
Classes bring people together to bond over tough workouts. Make new friends with similar goals, help each other get better — maybe even travel with your classmates to HYROX competitions around the world.
