THIS OCTOBER, YOUR WORKOUT CAN MEAN A LITTLE MORE.

All month long, our Best Fitness are coming together to raise money for cancer treatment, research + the people in our communities impacted by it.

And one of the easiest ways to be part of it? Come move with us.

We have donation-based specialty classes happening across our clubs throughout October - from yoga + Pilates to cycling, strength, and more.

Every class is a chance to sweat for something bigger, support an incredible cause, and show up alongside your BEST community.

NASHUA! We’re adding Pilates Fusion to the schedule starting Wednesday, 10/7, and we’re SO excited to welcome Sophia Sargent to the BEST crew!

You may recognize Sophie from in front of the camera as a television host, multimedia journalist + on-camera reporter for Biohack Yourself Magazine , covering all things health, wellness + longevity.

But now she’s bringing one of her own favorite ways to move to the studio. ✨

Expect a class that blends that Pilates control + shake we love with a little fusion to keep things challenging, fun, and feeling GOOD.

Six weeks isn’t a huge commitment. It’s a catalyst.

BLEAN isn’t about spending the rest of your life “on a challenge.” It’s six weeks to learn your nutrition, work with a coach, build better habits, and actually understand what works for YOU.

Will you see changes when you commit to those six weeks? Absolutely.

But the bigger win is everything you get to take with you after the challenge ends.

Six weeks to learn it. A lifetime to use it.

Ready for your catalyst? Join the BLEAN Challenge right now. Link in bio. We start next Monday.

Events. Donation-based classes. Special collabs. Fundraising opportunities. And yes… some fun merch.

10 clubs. Different communities. One mission.
