From the reviews

I been attending 9Round West Cobb since mid February. I always enjoy the workout. It allows me to get in and out and the flexible hours work well with my schedule. All the trainers I deal with are great!

★★★★★ — Phillip, Apr 2021

9 round has an amazing fitness program with great trainers. The workouts are a quick 30 minutes, work with flexible schedules, and truly work your whole body. The workout changes every day so you never get bored and the trainers are always so motivating and very knowledgeable to help guide you every workout.

★★★★★ — Kayleigh, Mar 2022

I have been a member for two months now and absolutely love working out at 9Round Fitness!!! It is a great 30 minute full body workout. Connor, Andrew and Jasmine ( the trainers) all do a fantastic job of pushing you. The workout is high energy, fun and also challenging!!! No class times is also very appealing.

★★★★★ — Tino, Feb 2018

I have never "worked" out more than one class or two! Found 9Round and it has been incredible! The reason is it is a full body workout in 30 mins! I love that I can leave my house, workout, be back at my house within an hour! The energy is awesome and they push you to do the best you can!

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.
