Today we honored Marsha P. Johnson in our annual Pride workout benefitting the OUT Foundation 🎉🏳️‍🌈

Marsha's legacy at Stonewall (and beyond) reminds us of our fundamental human rights to love who we love, to wear whatever clothing we want to wear, and to gather [whether in a gay bar or in a gym] without the risk of government interference.

Thank you to everyone who donated to the OUT Foundation and their incredible work to remove the barriers that block LGBTQ+ individuals’ access and participation in fitness, health, and wellness.

As we all know, fitness + belonging can make a huge difference in anyone's life.

You can still donate to the link in bio or using QR code in the reel. Coach Molly is thankful & looking forward to her many burpees 🫶

This week we are saying "See you soon" to Mia ❤️

Mia is one in a million, and we've been so lucky that she joined us. Mia is someone who always shows up ready to work, someone with a positive outlook, someone who is friendly to everyone.

Sometimes this summer, she did double workouts AND worked a full day 🤯💪🏽

Thank you for always being "All In", Mia! We've learned so much from your work ethic and positivity.

Have a great first year of college, and come back to see us real soon 🫶

In honor of Thunderbolt's 12th Anniversary, we want to share some of our 5-star reviews ✨️ Thank you Marisa! 🫶

"Some places change vour bodv. Others quietly change your life. This gym has been both... Over time, I realized I wasn't just getting stronger physically. I was becoming more confident, more resilient, and more willing to believe in myself. The coaches genuinely care, meet people where they are, and celebrate every victory, big or small. The community is unlike anything l've experienced. People encourage one another, celebrate each other's progress, and create an environment where you want to keep showing up. I've learned that strength isn't only measured by the weight on the bar. It's found in consistency, courage, and the people who remind you that you're capable of more than you think! I'm incredibly grateful to be part of this community. What I've gained here extends far beyond fitness, and I know I'll carry these lessons with me for the rest of my life. Thank you for showing me the way and being such a safe place to land and evolve."
