Play Lounge

What to Expect

No experience required. Our classes are designed to make everyone feel welcome and get a great workout. Wear yoga-like attire (socks are optional) and bring a water bottle. We supply all props needed. We encourage new clients to arrive 15 minutes early to get a tour and meet your instructor.

Play Lounge

It’s easy to fit exercise into your life when you can bring the kids. Minors under 18 years of age are welcome. If minors are on the premises while guardians are in class, you must purchase a play lounge package. Reservations are highly recommended. Please reserve under your name and not your child’s name.


Our science-backed approach helps clients build strength, restore balance, increase endurance and energy, decrease stress, and rediscover the joy of movement. The transformative power of our workout is more than physical—and it extends far beyond the studio. Barre3 isn’t just about the hour you spend strengthening and balancing your body; it’s also about the empowerment you carry with you into your life.

Studio Owner

Mary Liff began her journey to barre3 ownership as an instructor in New Orleans, LA and later in Tulsa, OK. As a former dancer and cheerleader, Mary was always looking for a workout that would keep her motivated, challenged, and energized but what she found in barre3 was so much more. Its bright, vibrant community, holistic approach to wellness, and the commitment to innovative fitness is what truly made her love barre3. After years of working as a cardiac critical care nurse and of dedicated barre3 practice, Mary is honored to share her love for barre3 with the Boulder, CO community where her aim is to create balanced bodies and empower her clients from within.
