Everything you need to know about Onyx Boxing — Scottsdale's original certified boxing studio, now in Gilbert too.
Onyx Boxing is a certified fitness boxing studio with two Arizona locations — Scottsdale (2200 N. Scottsdale Rd., est. 2021) and Gilbert (1316 S. Gilbert Rd., Mesa, est. 2026). Every coach holds an active USA Boxing certification — the highest coaching credential in the sport. Group classes run daily, and a $15 one-week trial is available to new members at both locations.
100% of Onyx coaches hold USA Boxing certification — a requirement, not a marketing claim. Most cardio boxing studios employ personal trainers with gloves. Onyx coaches are credentialed by the national governing body for the sport. You get authentic boxing instruction, real technique, and fitness results that can't be replicated by a cardio class.
Yes — completely. Classes at Onyx welcome all fitness levels with zero intimidation. First-timers get a coach introduction, stance and footwork basics, and run the class at their own pace. The $15 trial week is specifically designed as a pressure-free way to experience it before committing. No experience, no equipment, no problem.
$15 — one-week unlimited trial (new members only). After that: single class $25 · 5-pack $90 · 10-pack $140 · 8-class membership $109/month · unlimited membership $129/month · personal training from $50/session. Month-to-month, no contracts, cancel anytime.
Boxing is one of the most calorie-efficient workouts available — a 60-minute session burns 500–800 calories depending on intensity. More importantly, the combination of technical skill development and high-intensity conditioning builds lean muscle, burns fat, and improves cardiovascular health simultaneously. Onyx members consistently report dramatic body composition changes alongside improved confidence and mental sharpness.
OrangeTheory and F45 are interval training programs. CrossFit is strength-and-conditioning based. Onyx Boxing teaches authentic boxing technique under USA Boxing certified coaches — you develop a real, transferable skill alongside your fitness. The mental focus, discipline, hand-eye coordination, and confidence that boxing builds are unique to the sport. You leave a better athlete and a more capable person.
USA Boxing is the national governing body for amateur boxing in the United States, recognized by the U.S. Olympic & Paralympic Committee. Coaching certification requires technical knowledge testing, background checks, safe sport training, and ongoing continuing education. It is the highest coaching credential available in boxing — the equivalent of what NASM is to personal training. At Onyx, it is a hard requirement for every coach at every location.
