We have become a "Stamina Family" and Scott has created a positive, supportive group that is really welcoming. I have tried a bunch of fitness classes out there- and Stamina gets my very highest recommendation.

Whether you're training for a race, a season, or just a life that demands more from your body, STAMINA meets you where you are. Our workouts blend classic cross training, HIIT, plyometrics, and sport-specific movement in a way that challenges beginners and seasoned athletes equally.
Classes are open to all ages and abilities. Come ready to work. Leave knowing what you're actually capable of.
