🇺🇸 LABOR DAY WEEKEND SCHEDULE 🇺🇸

OSF will be CLOSED Saturday–Monday for Labor Day Weekend!

This is the one full weekend we close every year to give everyone a chance to step away from the gym, enjoy the last little bit of summer and spend some time with family & friends.

Rest up, have some fun, eat some good food, get outside & enjoy the long weekend.

We’ll see everyone back at OSF on Tuesday!

Happy Labor Day Weekend!

It’s National Dog Day! And here at OSF, we happen to have a four-legged member on staff — our official gym mascot, Teddy!

Teddy isn’t the only pup you’ll see hanging around OSF, but he’s definitely the hardest-working member of the team. Between greeting members, supervising workouts, and keeping morale high, he takes his job very seriously.

Happy National Dog Day to all of the OSF pups!

FULL! 💗

Thank you SO much for the overwhelming interest in Girls Who Lift! We are officially FULL! 💪🏼

To make sure we can give everyone the attention, coaching, and learning experience they deserve, we’ve decided to limit the amount of attendees.

But don’t worry — this is just the beginning! 👀 We’ll be working through our schedule to see when we can add another class time and give more girls the opportunity to join us.

Stay tuned for future offerings! In the meantime, check out OSF for our functional fitness and bootcamp classes!💗🏋🏼‍♀️✨
