✖️Boxing 🥊 HIIT 🔥 Strength Training

Rumble Boxing Montclair is a boxing-inspired fitness boutique that combines the science of boxing with the transformative power of strength training. Each class is a 45-minute, high-octane 10 round fight with HIIT, metabolic conditioning, and the benefits of cardio in one seamless class. No two workouts are the same—so you'll never get bored—and the classes are beginner friendly so you can rumble at your own pace.

From walking through the doors on March 31st, 2025, just 3 days after receiving her breast cancer diagnosis, to becoming a valued member & staple of our Rumble Boxing community. Thank you, Andrea, for being brave and willing to share your story with us.

And to all our members, know that, no matter the challenge, we’re ALWAYS in your corner.

09/26/2026

This makes our day🤭

09/25/2026

Get your sleep tonight...bc tomorrow we push Hard Mode harder ‼️😮‍💨

The training is done. The teams are ready. Now we get to put all that work toward something bigger.

Rumblethon, we’ll see you tomorrow 🥊

What you see: the fighter’s toughness, confidence, composure
What you don’t see: everything a fighter is carrying behind it

For a sport built around showing strength, speaking openly about mental health has challenged the idea that struggling and being strong can’t exist at the same time.

Strength isn’t just what you can take, it’s knowing when you don’t have to take it alone.

That’s what’s behind Rumblethon.
Showing up together, putting purpose behind the punches, and supporting The Jed Foundation as they work to make sure teens and young adults have the support they need when they need it 🖤🥊

09/24/2026

We just want to show you around the studio🥲

09/24/2026

Johnny Bananas knows a thing or two about a Challenge 👀

This one comes with gloves, a team, and a big reason to show up.

Rumblethon is THIS weekend, see you there 🥊

09/20/2026

New week, new goals. Drop a comment if you’re coming into class this week 🙌

09/18/2026

The game wouldn’t be the same without them 🥊

Different countries, different generations, different ways of fighting, but from Durán and Chávez to Serrano and Canelo, these fighters haven’t just been part of boxing history, they’ve helped write it ✍️

09/17/2026

We just want the best for you🤩
