From the reviews

I’m not even sure I want to talk about this place I mean I literally die here 3 times a week 🤣🤣🤣 Ok no seriously Danny is the manager and he’s absolutely amazing. How he remembers everyone’s name is beyond me but as you enter the building there he is with a big smile on his face.

★★★★★ — T, Mar 2022

Don’t pay attention to the negative reviews! I’ve been a member off and on for 10years. The trainers are solid I’ve been in the best shape a 45 year old could ask for! Give it time to work and be patient with the classes you won’t be disappointed.

★★★★★ — Michael, Feb 2026

I’ve been a member for 7 years now and can honestly say this is the only gym that has kept me motivated. Most of my life I struggled to stay consistent and constant in going to a gym. Also, sometimes the environment at the other gyms I used to attend just wasn’t for me and the classes were boring.

★★★★★ — Lisa_N_, Sep 2024

So after my 11 year old son was bullied I went to go look at a few places to teach my son how to fight. When I came to knockout fitness in Goodyear I met the GM Brian and was shown everything. I have to admit this place is awesome. Not only kid friendly but they have classes so I too can train with my son.

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.
