Train with Kerry

For people of all ages and abilities

Exercise should be accessible for people of all ages and abilities. KB Fitness strives to meet each individual where they are in their fitness journey. Small class sizes and a welcoming environment, combined with creative programming allows for everyone to walk away from a workout feeling better than they did before they arrived.

"I love working out at KB Fitness! It is such a warm and welcoming community for both group classes and personalized training. The workout is always fun, safe, and sweaty!"
