Whoever has my voodoo doll, roll its shoulders back a few times. Slowly.

Marathon Sunday is HERE, which means road closures, detours, and parking that’s harder to find than an open Reformer at 6:30AM.

If you’re coming to our River North or Wicker Park studio tomorrow, plan ahead:
⏰ Give yourself extra travel time
🅿️ Expect limited parking and plan your route before you leave
🚇 Consider the CTA, walking, or biking if you can

And to every Member lacing up tomorrow: we see you. All those Fortify, Sculpt and Burn days were building toward this. Go get those 26.2. We will be cheering you on every mile.

Meet HYROX45: 45 minutes of high-intensity movement, built on Pilates. This is ONYX’s answer to functional fitness racing.

You’ll run, push, pull, carry, and press, and every rep traces back to core control. When fatigue hits, Pilates principles hold your form: breath, alignment, and precision under load.

Not ready to race? MAT45 is waiting for you too. 🖤

📲 HOW TO BOOK:
The easiest way to book is through the ONYX app. Set your filter to “River North Mat Studio” to see all available MAT45 and HYROX45 classes.

Your spot is waiting. See you on the mat.
