Burn 500–800 calories per class under certified USA Boxing coaches. Boxing is the most effective fitness activity available for fat loss — and Onyx Boxing teaches real technique that makes every session count. Your first week is $15.
Boxing burns more calories than running, cycling, rowing, or interval training — while simultaneously building lean muscle, improving coordination, and developing genuine skill. The combination of technical focus and physical intensity makes 60 minutes of boxing feel like nothing else available in Scottsdale or Gilbert.
Every punch engages your core, shoulders, hips, and legs simultaneously. Boxing builds functional strength across every major muscle group without the bulk associated with weightlifting.
A 60-minute boxing class burns more calories than almost any other group fitness format. The combination of technique work, bag rounds, and conditioning keeps your heart rate elevated for the entire session.
Knowing how to throw a proper jab-cross-hook is genuinely empowering. The mental strength and physical capability that boxing develops extends well beyond the studio into every area of life.
Boxing is one of the most cathartic physical activities available. The combination of intense focus required and physical exertion produces a post-class clarity and calm that members consistently describe as unlike anything else.
Unlike cardio boxing, Onyx classes develop actual boxing technique — footwork, defense, combination fluidity — that builds and compounds over time. Every class makes you better, not just tireder.
The Onyx member community is one of the most supportive in the Valley. Women of all ages, fitness levels, and backgrounds train together — beginners and experienced members in the same class, all pushing at their own pace.
Yes — boxing is one of the most effective activities for fat loss. A 60-minute boxing class burns 500–800 calories depending on intensity. More importantly, boxing builds lean muscle while burning fat, improving your body composition faster than pure cardio. Onyx Boxing members consistently report significant weight loss results within 30–60 days of consistent training.
A 60-minute boxing session at Onyx burns between 500 and 800 calories depending on your body weight and intensity. This makes boxing one of the highest calorie-burn activities available in a group fitness format — higher than cycling, yoga, Pilates, or most interval training programs.
Most members who train 3x per week consistently report visible body composition changes within 30 days. The combination of high calorie burn per session, lean muscle building, and improved metabolic rate produces faster results than steady-state cardio alone. Consistency is the key driver — the $15 trial week is the lowest-risk way to find out if boxing is right for you.
