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.

Stephanie Grimes
Stephanie Grimes
Studio Owner

Stephanie Grimes is a cardiac nurse turned barre3 client and instructor, and now the co-owner of barre3-Philadelphia. While working as a nurse, Stephanie spent her days promoting health to her patients, but she found it hard to practice what she preached. Long shifts in the hospital combined with unhealthy snacks as meals left her feeling tired and cranky. On her days off, Stephanie would try to make up for her unhealthy lifestyle by following a no-pain-no-gain fitness mentality and a less-is-more nutrition philosophy. Her body and mind were desperate for some barre3 balance. It wasn’t until her mom, now co-owner of barre3 Philadelphia, invited her to a class at barre3 Newtown, that Stephanie found an approach that served her body and mind. This lead her to become an instructor and, now, an owner. For Stephanie, sharing total-body wellness with clients is the most rewarding part of becoming part of the barre3 family. She and her mom, Sandy, are so excited to embark on this journey together as the first mother-daughter barre3 owner team.

Sandy Grimes
Sandy Grimes
Studio Owner

Sandy Grimes is a healthcare-executive turned barre3 owner. After retiring from an exceptional career with Johnson & Johnson, she began to focus on her avid interest in exercise and health, as well as giving back to her community. Finally, with some free time to evaluate options, she found that she was healthier and more energized with the balance she found at barre 3. The connection, the community, and the healthy results she found at barre3 sparked her to involve her daughter, Stephanie. Both Sandy and Stephanie became quickly hooked, and now they're excited to become co-owners of barre3 Philadelphia and continue their healthy, happy journey together.
