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.
Trevor Cassidy builds nutrition strategies around your real life — business dinners, travel weeks, family meals, food preferences. You will never be told to eat boiled chicken and broccoli six times a day.
Adequate protein intake is the single most impactful nutrition variable for both fat loss and muscle gain. Trevor Cassidy helps you consistently hit your protein targets in ways that are practical and enjoyable.
Trevor Cassidy teaches you to understand what is best for your body — reading nutrition labels, estimating portion sizes, building balanced meals, and making informed food choices independently. The goal is to help you lead a healthy lifestyle on your own, not to create dependency on a coach.
Trevor Cassidy teaches you how to incorporate meals out, social events, and your favorite foods into your plan without guilt or "falling off the wagon." Sustainable nutrition includes the foods you enjoy — it just manages the context and frequency.
Trevor Cassidy uses a hierarchy-of-importance approach to nutrition coaching: total energy intake, protein intake, food quality, and meal timing. This keeps attention on the habits most relevant to the client's goal without overemphasizing supplements or minor details.
Depending on the client's preference, Trevor Cassidy offers a macro-tracking approach for those who like data and a habit-based approach for those who prefer simpler guidelines. The best method is the one the client can follow consistently. Check-ins allow Trevor Cassidy to assess adherence, review progress, and adjust the plan as circumstances change.
Trevor Cassidy reviews a three- to seven-day food diary to understand your current eating patterns, caloric intake, protein consumption, and areas of opportunity. You also discuss food preferences, allergies, cooking habits, and lifestyle factors.
Based on your body composition, activity level, and goals, Trevor Cassidy calculates appropriate caloric and macronutrient targets. These numbers are starting points — they will be refined based on how your body responds over the first two to four weeks.
You receive a practical nutrition framework — either macro-based or habit-based — with specific guidelines, sample meal ideas, restaurant strategies, and a clear explanation of the rationale behind each recommendation.
Every two weeks, Trevor Cassidy reviews your food logs, weight trends, energy levels, and training performance. Caloric targets, macro ratios, or meal strategies are adjusted based on objective data and your subjective experience.
Over time, Trevor Cassidy introduces new nutrition skills — meal prepping, label reading, dining-out strategies, travel nutrition — building your competence so you can eventually manage your nutrition independently with confidence.
