ONYX BOXING

I would highly recommend Onyx for anyone that is looking for an all around full body workout or looking to improve their boxing technique. You do not need to be an experienced boxer to take a class! The classes are high energy and the trainers are kind, enthusiastic, and always willing to help each class participant. The aqua bags Onyx uses are unique and give the facility a great vibe. 5 stars!!!

I really like this studio (Mesa location). All 3 instructors I've had have been great- Valerie, Smiley and Cole. The vibe is upbeat and encouraging and the music, intensity and instruction all vary per trainer but are all pretty awesome. I also love the hydro bags vs a heavy bag. Overall this is a great workout in a central location for a decent price. My only suggestion would be for them to bring in a box fan or something for added airflow.

I cannot give this gym enough praise. I was visiting from out of town and took a boxing class with Steve. He was really energetic and motivational, and he took the time to make form and technique corrections in a patient and encouraging way. You can tell that he has a true passion for teaching and making sure his students stay safe and get as much out of the class as they can. The moves are also written on a screen so if you forget them, you can find your place again to follow along. I have previous boxing experience, but was pretty rusty; however, I didn't feel pressured to go faster or rush myself along to "keep up" with the class. I love that it was self paced and allowed me to focus on my own movements without feeling intimidated. Steve had also polled the class on music so it was nice to be able to have some input and set our own vibe. The gym was clean, and the bags, gloves, and mats were in good condition. I liked that they had towels available too. If I lived locally, I would be a regular. Highly recommend!

I was previously at a different boxing Gym and switched over to Onyx 5 years ago and haven't looked back. Steve has taken the best in class in terms of boxing workouts, boxing training, and overall boxing fitness and combined them all into a world-class experience at this gym. There are multiple class times to choose throughout the day as well as available 1 on 1 mitt-work, sparring, or overall technique improvement. The coaches are amazing and really good about not just standing behind a podium barking out combinations- but actually going from bag to bag and giving you timely and constructive feedback as you're boxing. Great music, lighting is perfectly dimmed so that you can focus on yourself, and a really fun and welcoming atmosphere. Try it yourself, you won't be disappointed.

I’ve been doing group boxing classes here regularly, and it’s one of the most fun and motivating workouts I’ve found. The coaches are incredible—Coach Sporty brings this high-energy, playful vibe that makes even the toughest rounds feel exciting, Coach Val is amazing at building confidence and nailing technique (perfect for anyone leveling up their form), and Coach Kayleen has this infectious positivity that keeps the whole class pumped and smiling through the sweat. The classes are so much fun! High-energy music, killer combinations, and that good energy from start to finish make every session fly by. There’s a real sense of community here—everyone cheers each other on, high-fives after rounds, and you leave feeling stronger and more connected. No ego, just support and good vibes all around. The girls at the front desk are seriously the nicest—always welcoming with big smiles, remembering names, and making check-in quick and friendly. The place is always clean, equipment is top-notch, and the overall atmosphere just makes you want to keep coming back. If you’re in Scottsdale and want a boxing spot that’s effective, uplifting, and actually enjoyable, this is it. The fun factor + great coaching + awesome community = my favorite workout routine. Highly recommend—give it a try, you won’t regret it!
