★★★★★ — Kevin, Oct 2021

One of the greatest gyms around regardless of what you want to do! I hadn't trained in 15 years, and all the staff welcomed me with open arms. Their commitment to satisfying the needs of their customers is truly awesome. All the coaches will meet you where you are, and help you improve no matter what.

★★★★★ — Quinton, Dec 2024

Peak is far and away the best gym experience I’ve had. I’ve done kickboxing at 4 different gyms, and Peak is the clear winner. Everyone is helpful and welcoming. Coach Aaron Lopez’s classes are outstanding - in 3 years I’ve never had a rerun. His classes are always unique, challenging, engaging and a killer workout.

★★★★★ — Shannon, Dec 2024

Best decision I’ve ever made with a gym. All I can say is WOW! The coaches are all so professional, and a lot of fun. Right when you walk in Cassie always makes you feel welcomed (: I’ve been going for about year now & not only has this gym helped my fitness goals but also my personal growth.

New to muay thai? Start at Peak Kickboxing / Jiu Jitsu

Peak Kickboxing / Jiu Jitsu 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 Peak Kickboxing / 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.
