From the reviews

Awesome, quick, and fun workouts!!! Literally can go anytime it’s open and jump right in. I used to take classes somewhere else but the times were so restricting and at 9round I can go anytime/easily adjust it to my crazy schedule. Trainers are also super helpful/fun! Love working out with Lewis each morning!

★★★★★ — Maria, Mar 2022

This gym but particularly one of their trainers has completely changed my perspective and routine on physical health. Lewis Torres has inspired me and worked with me everyday to become stronger and to build my skills. Every morning I wake up excited to come to 9rounds and train with Lewis.

★★★★★ — Kristen, Mar 2022

Not only I get a kickass workout, but I get to work my mind too. This is mentally engaging and forget that "am working out". It's a hardcore, but it's worth it. The feeling of being able to punch and kick with greater strength each day is empowering.

★★★★★ — Chopin, May 2025

9Round is by far one of the most effective and enjoyable workouts I’ve found. The trainers are absolutely outstanding—knowledgeable, encouraging, energetic, and genuinely invested in helping every member succeed. They push you to challenge yourself while making the workouts fun and accessible for all fitness levels.

New to kickboxing? Start at 9Round Fitness

9Round 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 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.
