Who We Are

More than a gym.

Chained Evolution is Waltham's premier boutique fitness studio, founded in 2017 with a simple belief: fitness should be personal, data-driven, and sustainable.

We're not a big-box gym with rows of equipment and zero guidance. We're a small team of dedicated coaches who integrate cutting-edge body composition technology with individualized programming. Every client gets a program built specifically for their body, their goals, and their life.

Our approach combines the precision of InBody 570 body composition analysis and Fit3D 3D scanning with the expertise of hands-on coaching. You'll never wonder if your program is working—the data shows exactly what's changing and why.

Philosophy

How we train

Data over guesswork

InBody 570 and Fit3D scanning give you objective data. No more wondering if it's working. You'll see exactly what's changing.

Sustainability over intensity

The best program is one you'll actually follow. We build habits that last, not 30-day fixes that fizzle.

Individualization over templates

Your program is built for your goals, your body, your schedule. There's no "standard program" because there's no standard person.

Honesty over hype

Real results take time. We'll tell you what to expect and be honest about what it takes. No false promises.
