The Evolution Fitness community
Who we are

Built on consistency.
Owned by family.

Evolution Fitness is a long-standing fitness facility built on consistency, hard work, and community. Today, under new ownership by siblings Jill and Chuck Miscavage, we remain committed to honoring that foundation while continuing to grow and evolve for the members who make this gym what it is.

01 / Our story

A new chapter on an established foundation.

Evolution Fitness has been part of the local fitness community for years, helping members build strength, confidence, and healthier lifestyles.

Today, the gym is owned and operated by siblings Jill Miscavage and Chuck Miscavage, who stepped into ownership with a shared commitment to preserve what makes this facility special while continuing to move it forward.

This is not a complete restart. It's a continuation.
