WHO WE ARE

Nexus Training Center

Nexus is a training space built on real coaching, clean fundamentals, and a welcoming community. We teach Boxing, Muay Thai, Brazilian Jiu-Jitsu, and Strength & Conditioning with patient instruction and smart progressions so beginners feel confident and experienced athletes keep getting better. No ego—just progress you can feel every week.

Our Mission

Help people move better, get stronger, and become more confident—one well-coached session at a time. We meet you where you are, then guide you to skills and conditioning that last.

Our Story

We started Nexus after years of seeing two extremes: gyms that were friendly but unstructured, and gyms that were tough but intimidating. We built something different—classes that are technically sound and beginner-friendly, where coaches actually coach and community comes first.

How We Coach

Every session follows a simple arc: warm-up & movement prep → technique breakdown → focused rounds or intervals → short finisher → cool-down. You’ll know what you’re doing, why you’re doing it, and how to progress next time.

NEXUS TESTIMONIALS

Best gym ever. Love the 24-7 access. Great equipment and a cool theme.

Chris Vedral

Great small gym in Murry Hill. Has a dark vibe and is open 24/7. I’ve trained with Jeff in the past and it’s nice to have a place near home/work to workout when I can fit it into my busy schedule. Definitely recommend joining to ward off the stress of this crazy world we live in!

Christopher Lahey

Great gym for the Murray Hill neighborhood! It’s clean, spacious, and has plenty of options for workouts. 24/7 access is great, and plenty of parking for any time of day.
