★★★★★ — Suicide, Apr 2025

I initially moved to this area in October ‘22 and did a couple trial runs at a few of the surrounding schools before settling on the UCS academy in March ‘23. This academy is a rare gem for a few reasons, 1. There’s an equal balance of Gi & Nogi BJJ. 2.

★★★★★ — Jesse, Nov 2023

For about 2 years I've been training at UCS Carlson Gracie Claremont. I initially came in to be trained in boxing, Muay Thai and kickboxing. However professor Jamar pushed me to try training in Jiujitsu as well. Super happy that he did, The team here is all like family and welcomes anyone.

★★★★★ — Kenneth, Feb 2022

I’ve been training here at UCS for the past year now. Jamar (our instructor) pays great attention to detail and makes sure we understand what we’re doing and when to apply it. I train BJJ and Muay Thai here and not only have I gained new skills but have also become part of the Carlson Gracie family.

New to kickboxing? Start at UCS - University of Combat Sports, Carlson Gracie Claremont

UCS - University of Combat Sports, Carlson Gracie Claremont 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 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 UCS - University of Combat Sports, Carlson Gracie Claremont

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.
