This strength and wellness studio made over $600K in its first year

What’s up Gym World?

If you’ve got extra space and aren’t sure how to use it, this model is worth a look.

Core Collective Brookline isn’t your typical gym. It’s a shared space where personal trainers and health professionals, like psychotherapists and pelvic floor specialists, work together under one roof to support clients both physically and mentally.

But the model doesn’t just benefit clients. It gives coaches and practitioners the tools, freedom, and environment they need to grow their own businesses without the overhead of running a full facility.

There’s:

• No front desk

• No revenue share

• No big team to manage

And it’s working really well. The studio made over $600K in its first year, including an average of $18K per month in rental income.

We sat down with founders Dr. Lisa Lewis (a licensed psychologist) and Tony Gentilcore (a veteran fitness coach) to learn how it all works. Watch their full story below.

If you’re short on time, here’s the quick recap:

The Concept

Core Collective is a 5,500 sq ft space that brings fitness and wellness together in one place.

One half of the space is for training. It’s by appointment only and includes Tony and seven other strength and conditioning coaches who offer either one-on-one or semi-private sessions.

Tony started coaching in 2002 and co-founded Cressey Sports Performance, one of the most respected athlete training facilities in the country. That experience, plus running his own gym, shaped how he built this model. Trainers rent space by the hour and get full access to the gym’s equipment.

It’s similar to FlexWerk Fitness and The Yard, where fitness professionals can grow their business without the overhead of owning a gym.

Each trainer is featured on Core Collective’s website with a short bio and a link to their own site or email, like this:

This helps potential clients find a coach who fits their needs and reach out directly, without going through a middleman.

On the other side of the facility, you’ll find Dr. Lisa, a practicing psychologist and certified addictions counselor since 2003, and a wellness team that includes:

• Psychotherapists

• Physical therapists

• A chiropractor

• A dietician

• A pelvic floor therapist

Practitioners rent private rooms either by the day or pay a flat monthly rate if they work full-time hours. Like the coaches, they operate their own businesses and are featured on the website with a short bio and contact link.

Dr. Lisa believes the foundation of good clinical work includes autonomy, competency, and connection. To support that, she organizes in-services throughout the year. These are professional development seminars for the wellness practitioners to learn from each other and improve client care.

It’s similar to how gym owners invest in developing their coaching staff. When coaches grow, the training improves, and so does the client experience. The same principle applies here.

How Profitable Is This Concept?

With decades of experience between them, Tony and Dr. Lisa have built a space that’s both profitable and purpose-driven.

Core Collective Brookline has only been open for a year but already generates between $52K–$61K per month. That’s more than $600K in annual revenue.

Here’s how that breaks down:

• Tony makes $22K–$25K per month from training 50 clients

• Dr. Lisa brings in $12K–$15K per month from her own clients

• Roughly $18K per month comes from rent paid by coaches and practitioners

Tony and Dr. Lisa say there’s still room to grow, and they expect rental income to eventually reach $25K–$30K per month once the space is full.

Why It’s Interesting

Core Collective’s concept is compelling because it’s simple, profitable, and low-maintenance. It also benefits everyone involved.

For practitioners and coaches:

• They run their own business and keep what they earn

• The space gives them everything they need without the cost of owning a gym or clinic

• They get to work alongside other skilled professionals in a collaborative, supportive environment

For clients:

• It’s convenient — they can train, get therapy, or see a specialist all in one place

• Care feels more connected, with experts who talk to each other and work as a team

• They get a personalized experience with professionals who love what they do

For gym owners (like you):

• You can turn unused space into steady rental income with minimal oversight

• The professionals you bring in have their own client base, which can increase foot traffic and visibility for your gym

• You don’t need to manage or market their services. They run their own business while adding value to your space

TL;DR

There were gyms. There were wellness clinics. But nothing that truly brought both worlds together in a way that supported both clients and professionals.

Until Tony and Dr. Lisa teamed up to build Core Collective Brookline.

The result is a streamlined, sustainable model that delivers great outcomes for clients and creates opportunity for the professionals inside it.

Tony and Dr. Lisa also shared how the idea for Core Collective came together and what they’ve learned from decades in fitness and mental health.
