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
Fat Loss Without Muscle Loss
Resistance training sends a powerful signal to your body to retain lean tissue during a caloric deficit. You lose fat, not the muscle that keeps your metabolism high and your body looking toned.
Sustainable Habit Change — Not a Diet
Trevor introduces small, sustainable changes that do not feel invasive or disrupt your current life. You learn to build meals around protein targets and whole foods without eliminating food groups or following rigid meal plans. These are skills you keep for life, not rules you abandon after twelve weeks.
Improved Energy and Mood
Clients consistently report sleeping better, feeling more energetic during the workday, and experiencing reduced anxiety within the first few weeks of training. Fat loss is a side effect of a healthier body.
Accountability and Availability That Keep You Consistent
Weekly check-ins, progress photos, and training log reviews ensure you stay on track. Trevor is also available via text and email between sessions — so when a question comes up at the grocery store or a social event, you have real-time support. He identifies stalls early and adjusts your plan before frustration sets in.
Body Composition Changes You Can See and Measure
Using circumference measurements, progress photos, and strength benchmarks, you will have objective proof that your body is changing — even on weeks when the scale does not move.
Our Methodology
Trevor structures weight loss programs around three to four strength training sessions per week, supplemented by low-intensity daily movement like walking. This combination maximizes caloric expenditure without the cortisol spikes and joint stress that come from excessive high-intensity cardio. Training sessions focus on compound lifts and supersets that elevate heart rate while building muscle — delivering both a metabolic and structural stimulus in the same workout.
On the nutrition side, Trevor uses a flexible framework: clients learn to hit daily protein targets (typically 0.8 to 1 gram per pound of bodyweight), build plates around vegetables and whole foods, and manage caloric intake without obsessive tracking. For clients who prefer structure, macro-based approaches are available. The goal is always the same — find the simplest sustainable system that creates a moderate caloric deficit without making you miserable. As NASM-certified trainer Trevor Cassidy puts it: "The best nutrition plan is the one you can actually stick to for six months, not the one that looks perfect on paper." Resistance training is central to this approach because it increases resting metabolic rate by about 7% (Westcott, 2012, Current Sports Medicine Reports), meaning your body burns more calories even at rest.
How It Works
Comprehensive Intake & Baseline Measurements
Trevor reviews your medical history, dieting history, food preferences, and lifestyle factors. Baseline measurements — weight, circumferences, progress photos, and initial strength tests — establish your starting point.
Training & Nutrition Plan Delivery
You receive a strength-focused training program and a nutrition framework calibrated to your caloric needs, schedule, and food preferences. Trevor explains the reasoning behind every recommendation so you understand the why, not just the what.
Weekly Training & Biweekly Check-Ins
You train three to four days per week, either in person across NYC and NJ or through your online program. Every two weeks, Trevor reviews your progress data and makes targeted adjustments to training volume, caloric intake, or both.
Plateau Management & Plan Evolution
When fat loss slows — and it will — Trevor has a systematic approach: adjusting cardio, cycling calories, introducing diet breaks, or changing training stimulus. You never stay stuck for long.
Maintenance Transition
Reaching your goal weight is only half the job. Trevor guides you through a reverse dieting phase that gradually increases calories back to maintenance, locking in your results without the rebound that follows most diets.
