Sport-specific performance coaching from NASM-certified trainer Trevor Cassidy, available in Newark, New Jersey and online.
Clients in Newark can get evidence-based sports performance training from NASM-certified trainer Trevor Cassidy. Train the way your sport demands — faster, more powerful, and harder to beat. Your program is tailored to your body, goals, and schedule from the first assessment onward.
Newark is New Jersey's largest city with roughly 300,000 residents and a cultural and economic powerhouse undergoing significant revitalization. From the Ironbound district's world-class Portuguese and Spanish restaurants to the growing downtown arts scene around NJPAC and the Prudential Center, Newark is a city of distinct neighborhoods each with their own character. Branch Brook Park, which hosts over 5,000 cherry blossom trees — more than Washington D.C. — is one of the great urban parks in the Northeast and a standout training venue.
Newark's population of nearly 300,000 is one of the most diverse in the country, with large Portuguese, Brazilian, Haitian, and African American communities. Clients range from downtown professionals and Rutgers-Newark or NJIT students to Ironbound families, each bringing unique fitness goals and cultural perspectives. Weekend morning sessions and midday weekday sessions are the most popular across Newark neighborhoods.
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.
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.
A tennis match and a 10K race tax completely different energy systems. Trevor Cassidy programs conditioning that mirrors the work-to-rest ratios and intensity demands of your specific sport.
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.
Every sports performance program begins with a needs analysis covering the sport's movement patterns, energy systems, competition schedule, and common physical demands. Trevor Cassidy then assesses relevant measures such as jumping, sprinting, agility, and strength to identify priorities for the training block.
Off-season work may emphasize strength and muscle development. Pre-season blocks shift toward power, speed, and sport-specific conditioning, while in-season volume is managed around practices and competition. A meta-analysis by Rhea and Alderman found that periodized strength programs were more effective than non-periodized programs, with outcomes influenced by training status and program length (Research Quarterly for Exercise and Sport, 2004).
Trevor Cassidy 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.
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.
Plyometric and speed work require precise technique to be effective and safe. In-person sessions with Trevor Cassidy ensure your landing mechanics, sprint form, and explosive movement patterns are dialed in.
Every six to eight weeks, Trevor Cassidy retests key performance metrics. Improvements in jump height, sprint times, or agility scores confirm the program is working and guide the next training phase.
