Training in Chelsea
Chelsea occupies Manhattan's west side roughly between 14th and 34th Streets, anchored by the High Line elevated park, the Chelsea Market, and the sprawling Chelsea Piers sports complex on the Hudson River. The neighborhood blends a thriving art gallery scene with modern luxury residential towers and classic brownstones. Chelsea Piers alone offers world-class training facilities, making this one of the most fitness-friendly neighborhoods in all of New York. Google's New York headquarters on 8th Avenue and a cluster of tech and media offices have brought a younger professional population to the neighborhood in recent years.

Chelsea attracts young professionals in tech, media, and fashion along with established residents who have lived in the neighborhood for decades. The area has a strong fitness culture, and many clients here are already gym-experienced and looking for expert guidance to break through plateaus. Chelsea clients skew ages 28 to 45 and often prefer evening sessions between 6 and 8 PM or Saturday mornings after a weekday of office work.
Key Benefits
Train Anywhere, Anytime
Your program lives in a mobile app accessible from any gym, home setup, or hotel fitness center. No schedule coordination required — you train when it works for you and log your results afterward.
Video Form Reviews for Technical Accuracy
Record key lifts and submit them through the app. Trevor reviews your footage and provides detailed form corrections — addressing bar path, joint angles, tempo, and bracing — so your technique improves even without in-person cueing.
Programming That Adapts to Your Equipment
Whether you train at a fully equipped commercial gym, a bare-bones home setup, or a hotel with only dumbbells and a bench, Trevor writes programs that maximize the equipment available to you.
Lower Cost Than In-Person Training
Without the overhead of in-person session time, online coaching delivers high-quality individualized programming at a significantly lower price point — making expert guidance accessible on a broader range of budgets.
Weekly Accountability and Communication
Regular check-ins via messaging keep you accountable and allow Trevor to address questions, adjust programming, and provide the coaching support that separates online training from working out alone.
Our Methodology
Trevor uses a periodized programming approach for online clients identical to what he builds for in-person clients — the only difference is the delivery format. Programs are written in four- to six-week blocks with clear progression targets, and every exercise includes video demonstrations so you know exactly what each movement should look like. The training app tracks your loads, reps, and RPE (rate of perceived exertion) across sessions, giving Trevor the data he needs to make informed programming adjustments.
Form review is the backbone of the remote coaching process. Trevor asks online clients to film one to two key lifts per week — typically the primary compound movement of the day — and submit the footage through the app. He responds with timestamped video or written feedback addressing specific technique points. This iterative process produces meaningful technique improvements over weeks, even without in-person hands-on coaching. NASM-certified trainer Trevor Cassidy applies the same periodized programming principles used for in-person clients — and periodized programs produce 36% greater strength gains than non-periodized approaches (Rhea & Alderman, Journal of Strength and Conditioning Research), regardless of the delivery format.
How It Works
Online Intake & Video Assessment
You complete a detailed questionnaire covering training history, goals, available equipment, schedule, and injury history. Trevor may also request video of key movements to assess your current technique and mobility.
Custom Program Delivery via Training App
Your individualized program is loaded into the coaching app with exercise videos, set and rep targets, tempo prescriptions, and rest periods. Trevor walks you through the program via video message or call to ensure you understand the structure and goals.
Weekly Training, Logging, and Form Submissions
You train on your schedule, log every session in the app, and submit video of key lifts for form review. Trevor monitors your logs and provides technique feedback within 24 hours.
Weekly Check-In and Programming Adjustments
Each week, Trevor reviews your training data, bodyweight trends, and subjective feedback. Programming adjustments — load changes, exercise swaps, volume modifications — are made based on your progress and recovery.
