I've been with Stacey for two years, since I was diagnosed with prostate cancer. She has been the most valuable part of my team of recovery and moving forward in my life!

Kathy, I have to thank you for all your amazing workouts. Today I was told I had a nice butt. It was looking firm. lol. This was the first time I have EVER been told this. I was always told I had a Buffalo butt, bubble butt, bazooka butt but never nice!

Kelly, SC

Wow! I was feeling my body after the workout, enough to know I worked my muscles. I definitely notice a difference in my energy level, balance and mobility since being with you both!

OUR STORY

Join our Fitness Community

In 2000, Core V3 Fitness was founded by Stacey Vachon and Kathy Gendelman with one clear mission:

To create a safe, empowering, and personal space where you can move with confidence, rediscover your mojo, and build habits that support a vibrant, healthy life—at any age.

What started as a vision has now evolved into a dynamic virtual studio and thriving community rooted in our signature CV3 Method: core-focused, functional, and designed for real people with real schedules.

We now offer a complete system of live and on-demand workouts that range from 35 to 60 minutes, all created to help you build strength, mobility, and balance—without the overwhelm.

CORE V3 = Core Values/

1. Fitness – Stay consistent, energized, stronger

2. Fun – Energy, laughs, and a tribe that lifts you up
3. Longevity – Move strong today, for years to come
