Strength is in numbers, they say, and that statement has never been truer than here at Colorado Athletic Club-Flatirons. Experience the incredible energy that only our group fitness classes can give you. We’re powered by lots of variety, inspiring music, friendly faces, and the Boulder area's most dynamic and motivational certified instructors. What are you waiting for? Grab your water bottle and let’s strengthen, stretch, swim, sculpt, sweat, kick, punch, lift, pedal and plank…together.

With a mix of more complimentary classes than you can shake your Zumba with – like Water Fitness, Barre Burn, Cardio Chisel, yoga and Pilates – you’re able to exercise your options every day of the week. Short on time or just need an effective pick-me-up during your lunch hour? Join one of our Certified Personal Trainers for Core Express, a 15-minute workout that uses equipment such as BOSU balls, stability balls and gliding discs to train your core in a variety of ways.
