Personal Training
Muscle Building Training in Toronto
Our muscle building clients average +10 to +14 lbs of lean mass over 6 months — tracked bi-weekly through InBody 770 body composition scans, not scale weight. Periodized resistance training, recovery management, and data-driven nutrition built from your intake numbers. A program built from your body, not a template. Led by Jay Arzadon — CSCS, Kilo Level 3 Strength Coach, 100+ transformations since 2017.
Programs from $377/month, all-inclusive.

You lift consistently. You track your workouts. But your muscle building results aren’t following. Muscle growth responds to specifics — periodized load structure, nutrition timing around your training sessions, and what your structural balance assessment reveals about which muscle groups are limiting your progress. Without that data, muscle building stalls.
The Science
Why muscle building stalls — and what structural testing reveals
Progressive overload only works when the right muscles are doing the work. Most people training consistently for two or more years hit a wall because structural imbalances cap the performance ceiling before volume does. Weak rotator cuffs limit bench press. Underdeveloped glutes reduce squat mechanics. Hip flexor tightness bleeds force out of every lower-body movement. The structural balance assessment identifies these limiters before training starts — not after an injury forces the conversation.
Muscle protein synthesis (MPS) requires three inputs: training volume as the mechanical stimulus, dietary protein as the anabolic trigger, and recovery as where the actual tissue remodeling happens. Sleep restriction cuts MPS by approximately 20%. Suboptimal protein timing blunts the post-training window. Our intake assessment measures metabolic rate for precise caloric targets, biosignature indicators for recovery capacity, and training history for volume tolerance. All three are addressed from week one.
The InBody 770 measures segmental lean mass by limb. If the right arm consistently lags the left, or one leg carries significantly less muscle, that asymmetry becomes the first program target. Vlad gained 14 lbs lean mass in 16 weeks and his squat increased 80 lbs. His structural assessment showed a significant posterior chain deficit. The first 4-week block focused there. But the loading work built on a foundation that didn't exist before the assessment.
Structural balance
Asymmetry is the limiter nobody measures
Strength ratios between push/pull, left/right, and upper/lower determine how much load the program can apply before injury risk rises. We measure these at intake and build the first block around the weakest link.
Progressive overload
Volume must increase in 4-week blocks
Periodization structures load in controlled phases: neuromuscular adaptation, hypertrophy, and consolidation. Without a 4-week progression structure, most programs stall at the same weight for months.
InBody 770 lean mass tracking
Muscle gained, fat stored — measured separately
Bi-weekly segmental lean mass scans show exactly how much muscle was added and whether the caloric surplus is producing fat storage alongside it. The numbers adjust the nutrition in real time.

Data-Driven Growth
Why data matters for muscle building
Most lifters track weight on the bar but ignore the metrics that actually predict muscle growth: total volume load, progressive overload rate, lean mass changes, and recovery markers.
Bi-weekly InBody scans track lean mass gains to the tenth of a pound. Strength metrics are logged every session. If the data shows you are not growing, we adjust immediately.

The Protocol
What your first 12 weeks of muscle building training actually look like
Most hypertrophy programs apply the same template regardless of who's running it. Arzadon starts with a structural assessment. What we find in the first session determines which muscles get prioritized, what load progression looks like, and how much surplus is appropriate for your starting composition.
Week 1
Structural baseline
InBody 770 body composition scan, structural balance movement screen, and strength ratio testing. We measure left/right asymmetries, push/pull balance, and hip/shoulder function. The weakest structural link becomes the first program priority — before any maximum-load work begins.
Weeks 2–6
Neural adaptation and technique
The first block builds motor patterns and establishes baseline loads across all compound movements. Caloric surplus set at 300–500 kcal above maintenance. Protein at 1g+ per lb of target bodyweight. First comparison InBody at week 4 shows lean mass gained vs fat stored — the surplus adjusts accordingly.
Weeks 7–12
Hypertrophy loading
Volume and load increase in the second block. Accessory work targets the structural deficits identified at intake. By week 12, the InBody data shows the exact lean mass gained and whether the caloric surplus was appropriately sized. Most clients gain 6–12 lbs lean mass in this 12-week window.
Training at King West, Toronto: The studio is at 460 Richmond St W, 5 minutes from King Street West and walkable from Liberty Village, the Financial District, and the Entertainment District. Early morning and evening slots available for professionals commuting from downtown or midtown.
