Lose fat and keep it off with training and nutrition strategies that actually last.
Sustainable weight loss requires more than calorie counting and cardio. NASM-certified trainer Trevor Cassidy combines resistance training, conditioning, and practical nutrition coaching to help clients reduce body fat while maintaining strength and lean tissue. The program is built on changes that fit your normal routine rather than short-term restriction.
Many clients have already tried meal replacement products, group classes, or restrictive diets that were difficult to maintain. Trevor Cassidy instead builds a progressive strength plan and a nutrition framework around the client's schedule, preferences, and starting point. Clients using prescription weight-management medication should follow their prescriber's guidance; Trevor Cassidy can adapt the exercise plan to the limitations and recommendations provided by the client's medical team.
Trevor works with weight-loss clients across NYC and Northern NJ and through online coaching. Each client receives an individualized training plan, nutrition guidance within Trevor Cassidy's professional scope, and ongoing support between sessions. A systematic review found that combined behavioral weight-management programs addressing diet and physical activity produced better long-term outcomes than single-component programs (Johns et al., 2014).
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.
Trevor Cassidy 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.
Regular training can support sleep, daily energy, and stress management. Trevor Cassidy tracks how the program affects recovery and adjusts training demands when fatigue, soreness, or schedule pressure changes.
Weekly check-ins, progress photos, and training log reviews ensure you stay on track. Trevor Cassidy 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.
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.
Trevor Cassidy structures weight-loss programs around resistance training, conditioning, and regular low-intensity movement such as walking. The frequency and intensity depend on the client's training history, schedule, health, and recovery. Training sessions use exercises that build strength while contributing to overall activity.
On the nutrition side, Trevor Cassidy uses a flexible framework: clients work on appropriate protein intake, balanced meals, food quality, and portions without requiring obsessive tracking. Macro-based approaches are available for clients who prefer more structure. The goal is to find a sustainable system that supports a moderate energy deficit while preserving training quality. 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." A review in Current Sports Medicine Reports summarizes how resistance training can support body composition and metabolic health.
Trevor Cassidy 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.
You receive a strength-focused training program and a nutrition framework calibrated to your caloric needs, schedule, and food preferences. Trevor Cassidy explains the reasoning behind every recommendation so you understand the why, not just the what.
You train three to four days per week, either in person across NYC and NJ or through your online program. Every two weeks, Trevor Cassidy reviews your progress data and makes targeted adjustments to training volume, caloric intake, or both.
When fat loss slows — and it will — Trevor Cassidy has a systematic approach: adjusting cardio, cycling calories, introducing diet breaks, or changing training stimulus. You never stay stuck for long.
Reaching your goal weight is only half the job. Trevor Cassidy 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.
Stop cycling between diets that don't last. Book a free consultation with Trevor Cassidy to build a weight loss plan grounded in strength training, real nutrition, and lasting habits.
