Meet Eric

Founder & Head Coach, Kin Fitness

NSCA-Certified Personal Trainer, 

ACE Youth Fitness Specialist

Eric McCaslin

Kin Fitness was founded on one core belief:

Exercise should support your life — not compete with it.

​

With over 15 years of experience coaching adults, athletes, and families, Eric is passionate about helping people move better, build confidence, and train in a way that feels sustainable for the long run.

​

His coaching style blends thoughtful assessment, smart programming, and encouragement — meeting each client where they are and building from there.

​​​

Right at the start, he focuses on how you move — identifying imbalances, improving mechanics, and creating a foundation that supports long-term strength and resilience.

​

Whether you're returning after time away, managing aches and pains, or looking to take your training to the next level, Eric builds a plan that works for your body — not against it.

​​​

As a member of the Newburyport community and a parent himself, Eric understands the demands of real life — work, family, stress, and everything in between.

​

Kin Fitness was built to be more than a gym. It’s a place where:

• Adults feel supported
• Kids build confidence
• Families grow stronger together
• Progress is celebrated

 

That community-centered focus is at the heart of everything he does.
