From the reviews

This place is so convenient and the coaches are incredibly helpful and show genuine curiosity about their clients’ goals and just who they are as people. The workouts are as intense as you want to make them. I really feel like I’ve been motivated to push myself. Definitely recommend.

★★★★★ — Rex, Mar 2026

I have just started coming here, and I already love this place! Everyone is very welcoming and inclusive to beginners, and the instructors here are excellent teachers as well. I can't wait to come here more!

★★★★★ — Naomi, Feb 2026

I’ve been attending 9Round for a few days now, and I’m impressed with the experience. This is fun and challenging and it’s very different from traditional gym. I wish there was 9Round in the United Kingdom. The workouts are high-intensity, full-body, and leave you feeling accomplished after each session.

★★★★★ — Madhuri, Mar 2025

I've been debating on trying out boxing for quite some time, and randomly found 9rounds online and checked it out. The trainers are extremely kind, supportive, and want you to succeed! If you're a student like me, they accommodate to that as well!

New to kickboxing? Start at 9Round Kickboxing Fitness

9Round Kickboxing Fitness 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 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 9Round Kickboxing Fitness

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.
