From the reviews

★★★★★ — Shadow, Feb 2025

I joined their N 7th St. (@Greenway Pkwy) location (Phoenix) in March 2023. Prior to that, I had never done any boxing or martial arts. When I joined, I purchased a set of Flurry gloves and a wraps from their gear shop. They offer a schedule of boxing and kickboxing classes (1 hour).

★★★★★ — Ken, Mar 2025

★★★★★ — Haley, Jun 2025

I am very new to this gym but as an incredibly nervous and insecure person looking to make a lifestyle change, my first experience at knockout has been so positive and i feel really optimistic about making a change in my life! Upon my first visit I was really hesitant and nervous about trying something new.

New to kickboxing? Start at Knockout Fitness

Knockout 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 Knockout 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.
