★★★★★ — Museveni, Nov 2025

I was there today at the grand opening and it was on point ! The staff and coaches were really friendly and helpful. Everything there is brand new and I took advantage of the weights before the class started and I got a really good workout in ! I recommend this gym to all in the area of 35ave Bethany home rd.

★★★★★ — Ray, Aug 2025

I was visiting Arizona and wanted to try boxing as a complete beginner. I ended up in kickboxing classes instead — and I loved every minute of it. The experience was fun, safe, and energizing from the very first session. Staff ⭐⭐⭐⭐⭐ The team is exceptional. I met manager Tony, along with Jasmine, Isabella, and Connie.

★★★★★ — Jake, Mar 2026

I can’t say enough great things about this kickboxing class! The energy is amazing from start to finish—the music keeps you moving, and the instructors are so motivating, supportive, and fun. Every workout feels challenging but enjoyable, and I always leave feeling stronger and more energized.

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.
