OrangeTheory is an excellent cardiovascular program with strong accountability systems. If you want to optimize heart rate zones and track splat points, it delivers. If you want to develop a real skill alongside your fitness — something that makes you more capable and confident beyond the gym — boxing wins. Onyx also costs less per month and gives you a more generous trial week.
F45's 45-minute functional circuits are efficient and varied. But at many Scottsdale locations, F45 costs over $220/month. Onyx Boxing's unlimited membership is $129/month with certified coaching that F45 instructors don't hold. For calorie burn, both are comparable. For coaching quality and skill development, boxing is in a different category.
CrossFit and boxing are the two most skill-based options on this list — both develop genuine athletic ability. CrossFit excels at building strength and power. Boxing excels at speed, coordination, and cardiovascular endurance. For beginners, boxing has a gentler entry point — no Olympic lifting to learn, lower injury risk, and Onyx's $15 trial removes the financial barrier completely. Both are excellent long-term commitments.
Every Onyx Boxing coach holds a USA Boxing certification — issued by the national governing body for amateur boxing in the United States, recognized by the U.S. Olympic & Paralympic Committee. This is not a marketing credential. It requires technical examination, background check, safe sport training, and ongoing continuing education.
For comparison: OrangeTheory coaches hold NASM or ACE fitness certifications — excellent for general training, but not specific to boxing technique. F45 credentials vary. CrossFit L1/L2 certifications cover strength and conditioning methodology.
When you train under a USA Boxing certified coach, you learn boxing the way it's actually taught. The footwork, the head movement, the combinations — all correct from day one. That matters for both safety and results, and it's why the Onyx coaching standard is non-negotiable at every location.
Both deliver strong cardiovascular results. Boxing adds real skill development alongside the workout — you build genuine boxing ability at the same time. At Onyx Boxing in Scottsdale, USA Boxing certified coaches teach authentic technique. OrangeTheory delivers interval cardio with heart rate monitoring. The best choice depends on whether you want fitness only, or fitness plus a real transferable skill.
F45 is a functional circuit program. Boxing at Onyx teaches sport-specific technique under certified USA Boxing coaches. For calorie burn both are comparable. The key difference: boxing builds cumulative skill you improve on indefinitely. F45 workouts don't compound in the same way. Onyx also costs significantly less per month than most Scottsdale F45 locations.
Both are excellent. Boxing typically burns 500–800 calories per hour while developing coordination, reflexes, and mental focus. CrossFit excels at building strength and explosive power. For beginners, boxing has a lower barrier — no Olympic lifting to learn, lower injury risk, and Onyx's $15 trial week is the most generous entry point in the market.
Onyx Boxing offers the most generous trial in the market — one full week of unlimited boxing classes for $15. OrangeTheory and F45 typically offer a single free or reduced-price class. Onyx's week-long trial gives you enough time to genuinely evaluate the program before committing.
Yes — completely. Onyx Boxing classes welcome all fitness levels. USA Boxing certified coaches are trained to work with beginners from day one. No experience, no equipment (beyond athletic clothes), and no prior fitness level required. The $15 trial is specifically designed for first-timers.
