Strength and conditioning for everyday goals and everyday people.

ONE Boulder Fitness is staffed by named, credentialed people — nine certified personal trainers, a resident Doctor of Physical Therapy, a resident Registered Dietitian, owners Karie Kerner and Kyle (both on the floor most days), and Bucky, the three-legged club dog. Woman-owned, downtown Boulder, and nobody wears a uniform.








Two credentialed practices operate inside the club: Atomic Physical Therapy and ActivEnergy Nutrition.


Both owners are in the building most days. It’s the reason there’s only one club.


Roster and credentials are being confirmed with each team member ahead of launch. Kyle’s portrait is on the way.
