Classes Currently Offered
-
Hyrox Strength
This class is about raw strength — the kind that makes every sled push, wall ball, and sandbag carry feel a little easier. You’ll lift heavy, move with control, and focus on form under fatigue. Think less reps, more load, and smart programming that builds power without wrecking your joints.
Great for:
-Athletes looking to break through strength plateaus
-Newbies who want to build a strong, resilient base
-Anyone tired of “fluffy” workouts that don’t actually make you stronger
-
Hyrox Endurance
We combine running intervals with HYROX-style functional stations to train aerobic capacity, pacing, and mental grit. Expect to sweat — a lot — while dialing in the rhythm and control you’ll need on race day (or just to crush life outside the gym).
Great for:
-Newer athletes looking to build cardio confidence
-HYROX competitors refining their race strategy
-Anyone who wants to move longer without burning out
-
Hyrox Power
This is where speed meets strength. HYROX Power blends high-intensity intervals with plyometric movements and fast-paced functional circuits to develop the pop you need to move explosively and recover quickly. Perfect for building sprint capacity, reaction time, and the gear-shift ability to dominate race stations.
Great for:
-Competitors who want to level up their transitions and station times
-New athletes ready to move faster with purpose
-Anyone who just wants to train like an athlete
