From the reviews

This is where clubbing meets working out. Cannot say enough good things about Rumble Boxing Stamford. It was well worth the wait. The workout is a full body burn averaging 400-800 calories per 45 minute class.

★★★★★ — Jake, Dec 2025

Rumble Boxing is an amazing place with great energy, great coaches, and a real sense of community. Every workout pushes you to be better not just physically, but mentally too. The staff truly care about helping people improve, gain confidence, and succeed at their own pace.

★★★★★ — Camilo, Jan 2026

This boxing studio great, brand new. Eric is the manager and one of the most hardworking people I've met. You will see him at the studio at 5 am until 8pm every day. I prefer Dashaun's classes because he plays great music, but all of the instructors are beast!

★★★★★ — Anny, Jan 2026

I have been coming to this Rumble location since it first opened. As a postpartum mother I was really nervous and scared. I haven't taken a boxing class in probably 10+ years. But this has been such an amazing experience! The classes are intense but also have a club sort of vibe.

New to kickboxing? Start at Rumble Boxing

Rumble Boxing comes up as a beginner-friendly gym — noted on their own site. If you've never thrown a punch or a kick, that's exactly who a good beginners class is for. A few things worth knowing before your first week. First, you don't need to be fit or coordinated to start — you get in shape by training, not before it, and coaches scale every drill to you. Second, you won't be thrown into hard sparring — reputable gyms build the basics (stance, footwork, and punches and kicks on pads and bags) first, and any contact eases in gradually under a coach's control. Third, all fitness levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first kickboxing class at Rumble Boxing

Nervous about walking into a kickboxing gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling the basics — stance, footwork, and punches and kicks on pads or a heavy bag — not hard sparring. Go at your own pace and rest whenever you need to; no one will bat an eye. What to wear: comfortable athletic clothes you can move and sweat in, and supportive trainers. What to bring: water, and hand wraps and gloves if you have them — many gyms lend loaner gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves and wraps (and shin guards once you start sparring). Sparring is optional and eases in gradually, once your basics are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.

Kickboxing is a contact sport. Warm up, pace yourself, listen to your coaches, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
