From the reviews

Such an amazing workout! I haven’t sweat like this in years! The instructors push you in the best way, always offering modifications when needed. They even remembered my name since my very first visit, which made me feel so welcome. Hands down the best workout I’ve had in a long time!

★★★★★ — Sammy, Oct 2025

Awesome gym! I came to this gym to help strengthen my knee after 2 years recovering from ACL tear. Countless gyms, trainers, therapy, etc. for two years did not work, but Roque and Tania were fantastic trainers! They really made sure that your goals were the priority of each session.

★★★★★ — Kristina, Jun 2024

When I started Personal Training with RD1 Fitness I weighed 265lbs. I won’t lie - those workouts were intense and I was struggling a lot. No surprise…I wasn’t active too much at that time. I managed to continue though seeing the great effects at my body.

★★★★★ — Jacek, Jun 2021

I’ve only been going to RD1 for a few months now and it’s already changing my life! Physically and mentally I have never felt better. The trainers meet you where you’re at and find the perfect balance of motivating you, educating you, and pushing you to be better, all while making you smile as you challenge yourself.

New to muay thai? Start at RD1 Fitness

RD1 Fitness comes up as a beginner-friendly gym, going by their listing and members’ reviews. If you've never thrown a punch or a kick, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit to start — you get in shape by training, not before it, and coaches scale the conditioning to you. Second, you won't be thrown into sparring — reputable gyms build fundamentals (stance, footwork, and the basic strikes of the "art of eight limbs") for weeks before any contact, and sparring stays optional. Third, all 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 muay thai class at RD1 Fitness

Nervous about walking into a muay thai 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 on pads and bags — not fighting. Rest whenever you need to; no one will bat an eye. What to wear: shorts or athletic wear and a t-shirt; you'll train barefoot on the mats. What to bring: water and hand wraps if you have them — many gyms lend gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves, wraps, a mouthguard, and shin guards. Sparring is optional and comes later, once your fundamentals 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.

Muay thai is a contact sport. Ease in, 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.
