From the reviews

Top gym around, professional staff. World class trainers that have the best energy around. I have been to multiple Gyms around Colorado but Rumble Southlands takes the cake by far. Coach Drew is a Rockstar! One class and you are hooked!

★★★★★ — Cody, May 2023

Awesome coaches, and the workouts are highly addictive! I love cardio but need accountability for strength training, so Rumble is the perfect balance of both! I'm a founding member closing in on 200 classes and am never bored. Great variety, great vibe, and great community! Thanks, Rumble!

★★★★★ — Jessica, Nov 2023

Rumble is by far the most awesome fitness gym! I have been here for going on 4 months and enjoy coming in every single class. Even my mother mentioned to me that this is the most motivated she has ever seen me to go to a gym The coaches are absolutely wonderful (shout out) and encouraging.

★★★★★ — Allison, Aug 2024

Rumble was a great experience for me! I loved the coaches, the classes, and it's actually FUN to work out! I've lost 10 pounds so far and gained more muscle than I thought I had!

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.
