Hunter Rivera
Director of Speed and Agility
Personal Fitness Trainer
22 years old / NASM-CPT
Hunter is the definition of a well-rounded trainer. With a specialization in speed and agility, he also caters to all his clients' needs - building lean muscle, weight loss, strength training, flexibility and mobility, tracking nutrition, etc. Hunter has a 'training like an athlete' philosophy, meaning he would prefer to see all his clients move functionally and high-performing, shifting from the typical focus of only aesthetics. This DOES NOT only apply to kids but to adults as well!
Hunter has been training for the past 8 years under the mentorship of Joe DeMarco, both as a client and employee, as of late, after playing Division 1 baseball at UMBC and Mercer County Community College. He implements what he has been taught over the years into his own and creates a very workable and nurturing environment for his peers. He has his NASM-CPT certification to supplement his abilities to guide his clients with care and coaching with precision.
Hunter understands at the highest level the work ethic and dedication necessary to achieve your goals. He is a product and fine result of Demarco Training Systems that represents success and hard work. He will push you to your limitations and unleash your greatest potential. Let's get to work!
John Rivera
Personal Trainer
I am a 22-year-old personal trainer. Graduated with an associate's degree in exercise science, and I am NASM certified. My goal is to help you do better today than yesterday. I like to spend my time doing anything with physical activity like snowboarding, jujutsu, Pickleball, soccer, running, and plenty more. Having consistency is a big part of training and will help you, as a client, reach your goals a lot faster.
