From the reviews
I have been with Knockout Fitness Peoria for just over two months now and have had a really positive experience so far. I came to KO having never done any type of boxing or kickboxing training before but had passed by the gym location many times with curiosity and honestly just desperately needed something different.
I lost 15 lbs and in the best shape that I have in YEARS coming here 4-5 times a week for the last 2 months. I even cancelled my gym membership because it’s so effective. The coaches here are all super cool, supportive and encouraging.
I am extremely grateful to be a part of Knockout Fitness! The workouts are intense but calibrated to accommodate people of all ages and stages of life. The staff is extremely knowledgeable and encouraging, always willing to help us get prepared for success!
Awesome facility, great equipment, awesome kickboxing and boxing instructor lead classes. I’ve lost 40 lbs since they have opened!! I’m a father of three and don’t really have the time to spend hours in the gym. The 60 min class kicks my butt and really challenges me to push myself.
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.
