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.
