I enjoy trying new boxing gyms when traveling. Onyx didn't disappoint! Steve led an electric class filled with high energy, great combinations, great knowledge, and great workout. Will definitely be back anytime I'm in the area! Thanks!

Onyx boxing!!! The energy was immaculate, the coaches (Steve and Issam) are great and well educated, motivating, and encouraging! I had a great time during my workouts, pushed myself & felt fully immersed in the space! The method of training was a new experience for me (numbers vs. terms) which I appreciated for how it will round out my knowledge in boxing. Not a Phoenix native, but I’ll definitely visit again!

Onyx Boxing isn’t just a gym. It’s an experience. From the moment you walk through the doors, you feel it — the energy, the power, the vibe that sets this place apart. The coaches are passionate, grounded, and genuinely love what they do. Steve isn’t just the owner. He’s the heart of Onyx. His energy is magnetic and his coaching is unmatched. He sets the tone for the entire space. He leads with passion and confidence, and takes the time to connect with each person in class. He teaches proper form, encourages your growth, and pushes you past your limits without ever making you feel uncomfortable or out of place. If you’re looking for a place that challenges your body, fuels your mind, and helps you reclaim your power, Onyx is it.
