Your
transformation is Inevitable.
Toronto's only gym where trainers are paid on your results — not by the hour. 40+ metrics tracked. Assessment-first. No guesswork.
Arzadon Fitness is a data-driven personal training gym in King West, Toronto. Transformation programs covering fat loss, muscle building, body recomposition, and athletic performance — each tracked across 40+ metrics per client and delivered by trainers paid on your outcomes, not hours.
Since 2017, 100+ clients have completed measurable transformations under Jay Arzadon, Founder & Chief Performance Officer. Every transformation program starts with a full diagnostic assessment — not a guess.
Research published in JAMA (Mandsager et al., 2018, N=122,007) found that cardiorespiratory fitness is the strongest predictor of long-term survival — stronger than cholesterol, blood pressure, or BMI. According to the study, the least-fit individuals had 5× higher all-cause mortality risk than the top performer group. This is why every Arzadon program begins with VO2 max and biosignature testing before a single set is programmed.

Transformation
I can't say enough good things about my experience with Arzadon Fitness and their incredible 6 Month transformation program. If you're looking for results-driven fitness with a personal touch, this is the place to be!
+9 lbs muscle, body fat 18% → 9.5%, waist 32.6″ → 29″
Did a 3-month transformation. Went from 100 -> 66 heart rate. And no more stage 2 hypertension, I have a clean bill of health now and I won't need to rely on any lifelong medications.
Resting HR 100 → 66 · −7% body fat · +14 lbs lean mass · hypertension resolved
I started with Arzadon in August of 2024. I have lost 30lbs and had a body recomp I didn’t even know was possible in 4 months, and I have not even reached where I want to go.

How much does a personal trainer in Toronto cost?
At Arzadon Fitness, most clients invest from $377/month. This is an all-inclusive model that provides 24/7 facility access, personalized programming, nutritional architecture, and 1-on-1 coaching sessions. Unlike traditional gyms, we do not charge hourly per-session fees, ensuring our focus is entirely on your results.
What makes Arzadon different from other gyms in downtown Toronto?
We are Toronto's most data-driven personal training gym. We track over 40 data points per client, including VO2 max, biosignature, and InBody scans. Furthermore, our trainers are compensated based on your outcomes, not the hours they log. We focus on one metric: your result.
Do you offer personal training for women in Toronto?
Yes. We specialize in female fat loss and body recomposition. Our coaches, including those certified as Female & Male Transformation Specialists by the Clean Health Institute, design adaptive nutrition and hormonal strategies specifically tailored to women's physiology.
What is biosignature testing and why does it matter?
Biosignature Modulation is a scientific approach to spot reduction and body composition. By measuring specific skinfold sites, we can identify hormonal imbalances (like cortisol or insulin resistance) and create targeted nutritional and supplement protocols to accelerate fat loss.View our assessment process →
Where is Arzadon Fitness located in Toronto?
We are located in the heart of King West at 460 Richmond St W, Suite 100, Toronto, ON M5V 1Y1. Our private, state-of-the-art facility is designed for focused, distraction-free training.
How long until I see results with a personal trainer?
With our precision assessments and 12-week periodized programming, clients typically see measurable changes within the first 14-21 days. Significant transformations (like losing 20+ lbs or dropping 5-8% body fat) are routinely achieved in 12 to 16 weeks.
Do you offer gym memberships without personal training?
No. Arzadon Fitness is a private personal training studio, not a public gym. Every client works with a dedicated coach. This ensures accountability, proper technique, and measurable outcomes — none of which are possible in an unsupervised gym environment.
What is VO2 max and why should I care about it?
VO2 max is the maximum rate at which your body can consume oxygen during exercise. It is the single best predictor of cardiovascular health and longevity. We test VO2 max as part of our baseline assessment and track improvements over time.Learn about VO2 max testing →
