From the reviews

I went in for my free introductory experience and I really enjoyed it. He is very chill and laid back. Not pushy or aggressive. I felt comfortable working with him and thought that he gave great instructions. He is also super patient which put me at ease.

★★★★☆ — Danny, Aug 2015

I’ve been in the teenage class at crazy monkey for more than 3 years now. I’d never thought I’d be boxing. Tried it and loved it. I gained confidence, friendships and skills which really benefits in so many areas of my life. Being in the teenage class the coach makes the class feel like a brotherhood.

★★★★★ — Alex, Dec 2021

I’ve been coming here for a couple months now and I love it. Personally I do their Brazilian Jiu Jitsu sessions and the atmosphere is amazing. The coaches are really nice, professional, and educated in their craft and the students are also really fun and easy to get along with.

★★★★★ — Ryan, Sep 2021

Amazing Gifted and Giving coaches in BJJ, Crazy Monkey Boxing, Kettle-bells, Yoga, Mobility, all for one price. No contracts, No Pressure to sign up. PS.

New to muay thai? Start at K2 Gym, Boxing & Jiu Jitsu

K2 Gym, Boxing & 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 K2 Gym, Boxing & 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.
