Training in Belleville
Belleville is a compact Essex County township of about 36,000 on the Passaic River with deep Italian-American and increasingly diverse Latin American roots. The town has a blue-collar, hardworking identity centered around Washington Avenue and its surrounding residential blocks. Branch Brook Park's northern extension reaches into Belleville, and the town's own parks provide neighborhood-level green space for fitness activities. Belleville's location between Newark and Bloomfield puts it within 15 minutes of major employment centers in both cities.

Belleville is a working-class community with a mix of long-time Italian-American residents and newer Hispanic and Filipino families. Many clients here work demanding physical or service jobs and want training that builds functional strength, prevents work-related injuries, and helps manage stress. Evening sessions between 6 and 7:30 PM are the most popular, fitting around shift schedules and family dinner.
Key Benefits
Sport-Specific Power and Speed Development
Your program includes plyometrics, Olympic lift variations, and sprint mechanics tailored to the force vectors and velocities your sport demands. You get faster and more explosive in the directions that matter.
Reduced Injury Risk on the Field
Targeted strengthening of commonly injured areas — ACL-protective hamstring work for cutting sports, rotator cuff prehab for overhead athletes — keeps you competing instead of rehabbing.
Energy System Conditioning That Matches Your Game
A tennis match and a 10K race tax completely different energy systems. Trevor programs conditioning that mirrors the work-to-rest ratios and intensity demands of your specific sport.
Competitive Edge Over Opponents Who Only "Work Out"
Most recreational athletes train randomly. Structured sport-specific programming gives you a measurable advantage in strength, speed, and endurance against competitors who lack a real plan.
Our Methodology
Every sports performance program begins with a needs analysis: What are the dominant movement patterns, energy systems, and injury risks of the sport? Trevor then assesses the athlete — testing vertical jump, broad jump, sprint times, agility drills, and sport-specific strength benchmarks — to identify the biggest performance gaps. The training program targets those gaps systematically.
Programming follows a conjugate or block periodization model depending on the athlete's competitive calendar. Off-season blocks emphasize maximum strength and hypertrophy. Pre-season transitions to power, speed, and sport-specific conditioning. In-season programming drops volume to maintain gains while keeping the athlete fresh for competition. This structured approach ensures you peak when it counts — not in the gym on a random Tuesday. NASM-certified trainer Trevor Cassidy favors periodized models because the evidence is clear: periodized programs produce 36% greater strength gains than non-periodized training (Rhea & Alderman, Journal of Strength and Conditioning Research), and that strength advantage translates directly to on-field performance.
How It Works
Sport Needs Analysis & Athletic Assessment
Trevor evaluates the physical demands of your sport and tests your current athletic baselines — jump height, sprint speed, agility, strength-to-bodyweight ratios — to identify the areas where targeted training will yield the biggest performance gains.
Periodized Performance Program
You receive a multi-phase training plan aligned with your competitive season. Each phase has specific goals — build strength, convert to power, sharpen sport-specific conditioning — so you arrive at competition in peak form.
Coached Power and Speed Sessions
Plyometric and speed work require precise technique to be effective and safe. In-person sessions with Trevor ensure your landing mechanics, sprint form, and explosive movement patterns are dialed in.
Performance Retesting & Program Progression
Every six to eight weeks, Trevor retests key performance metrics. Improvements in jump height, sprint times, or agility scores confirm the program is working and guide the next training phase.
