From the reviews

I Was New To The Area.. I been looking for a martial arts school for my 5 year old daughter and I haven't been successful until I found Mercury Jiujitsu. My daughter Loves class looks forward to it daily.

★★★★★ — Shells, Aug 2025

My 5 yr old daughter started taking classes the end of April ,she is a shy and reserved girl and I wanted her to learn some self defense and gain some confidence in herself and that’s exactly what is happening.

★★★★★ — Velvet, Aug 2025

I would highly recommend Mercury Jiu Jitsu to anyone. It's a great "mom and pop" spot to learn and grow in a skill set within a safe and genuine environment. The most enjoyable part is the workout we get within the classes and the passion from the instructors.

★★★★★ — Phillip, Feb 2025

First let me start off by saying, Leo, Chris, Lucan & Adrian, its been a pleasure training with all of you. This gym is one of, if not the absolute best gyms in Poughkeepsie, NY. The trainers are really nice & let you learn at w.e pace you feel comfortable, its clean & everyone is there to help eachother.

New to muay thai? Start at Mercury Jiu jitsu

Mercury Jiu jitsu 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 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 Mercury Jiu jitsu

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.
