Key Benefits
Periodized Programming That Prevents Plateaus
Your program cycles through accumulation, intensification, and deload phases so your body is always adapting. This structured approach prevents the stalling that happens when you repeat the same routine month after month.
Technique Coaching on Every Major Lift
Trevor provides hands-on cueing for squat depth, deadlift hip hinge mechanics, pressing paths, and bracing patterns. Proper technique means heavier loads with less joint stress over time.
Real-World Strength and Functional Capability
Multi-joint, multi-plane exercises build strength that transfers directly to daily life. Loaded carries, rotational work, and single-leg variations develop the balance, coordination, and core stability that make everything outside the gym feel easier — from navigating subway stairs to playing with your kids.
Improved Balance, Coordination, and Joint Health
Functional movement training challenges your proprioception and stabilizer muscles. Better balance means fewer injuries, better athletic performance, and more confidence in your body. Training through full ranges of motion keeps joints healthy and mobile.
Measurable Progress You Can Track
Every session is logged. You will see your squat go from 95 pounds to 185, your deadlift climb, and your pressing improve. Objective numbers keep motivation high and guesswork out of the equation.
Our Methodology
Trevor builds each program using a movement-pattern framework layered with periodization science. Every session addresses the foundational human movement patterns — squat, hinge, push, pull, carry, and a core stability or rotational challenge — ensuring balanced development and training the body as an integrated system rather than a collection of isolated parts. Within that framework, linear and undulating periodization models drive progression based on your training age and recovery capacity.
Beginners typically start with a full-body linear progression three days per week, adding weight to the bar each session while building movement quality through functional variations — goblet squats, kettlebell hinges, loaded carries. Intermediate clients transition to weekly undulating models — alternating between heavier, moderate, and lighter training days — with exercises progressing from stable to unstable, bilateral to unilateral, and slow to fast as competence improves. Accessory work addresses individual weak points and movement limitations. If your lockout stalls on bench press, you might see close-grip variations. If your squat depth is limited by ankle mobility, targeted drills are woven into your warm-up. If an injury or setback changes the plan, Trevor adapts — there is always more than one way to keep you progressing. NASM-certified trainer Trevor Cassidy uses this approach because the research is clear: periodized programs produce 36% greater strength gains than non-periodized approaches (Rhea & Alderman, Journal of Strength and Conditioning Research).
How It Works
Functional Movement Screen & Goal Setting
Your first session includes a full functional movement screen — overhead squat, hip hinge, single-leg balance, push, pull, and rotational assessments — so Trevor can identify movement restrictions, asymmetries, and stability deficits before writing a single set. You will also discuss your training history, schedule, and specific goals.
Custom Program Design
Based on your assessment, Trevor builds a multi-week training block combining compound barbell lifts with functional movement patterns. Exercise selection, set and rep schemes, tempo prescriptions, and rest periods are all tailored to your level and goals — with warm-up protocols that address any movement limitations identified in your screen.
Coached Training Sessions
During in-person sessions, Trevor cues technique in real time — coaching squat depth, hip hinge mechanics, bracing on carries, and alignment on single-leg work. You learn to train with intention, not just effort, building body awareness alongside strength.
Progress Tracking & Program Updates
Every four to six weeks, Trevor reviews your training logs, reassesses key lifts and movement quality, and writes the next program phase. Load jumps, volume changes, and exercise swaps are all data-driven.
Long-Term Strength and Movement Development
Over months and years, your programming evolves — from foundational strength into more advanced methods like paused reps, accommodating resistance, and complex functional combinations. Exercises progress from stable to unstable, bilateral to unilateral, keeping progress consistent and training engaging.
