Sixth Street Underground

Motherhood requires strength. ♥️

You want them to see the best version of you?

The one that has energy for days?
The one that can best regulate stress?
The one that feels confident and capable?

Supporting your kids isn’t just about attending every one of their events and coordinating their practices, meals, etc.

Let them see you make time for taking care of yourself. Invite them in - show them that making time for your health is proving how much you value and respect both them and you. 🙌

Tired of not feeling like your best version of yourself? We can help.

There's a question we ask ourselves before we post, before we coach, before we design a single workout:

Are we selling the doorway, or the result?

Most fitness places sell the doorway — come in, swipe a card, burn calories, look a certain way.

We sell the result: feeling strong, capable, and sure of yourself. Not for a photo — for your life.

We're Sixth Street Underground. A coaching-focused gym on 812 6th Street in Boone.

We’d love to show you what we’re about and how we can get you the results you want most, all while being supported by an amazing group of people.

♥️🖤

Strength, fun, and support? Today brought all of those! 💪♥️

Big thanks to the APEX Fest Crew for bringing their Strongman Equipment to the Underground and leading a workout/showing us what strongman is all about!

This Saturday!!

Come see what the Ames APEX Fest/Strongman training is all about! 💪💪

All are welcome to learn, lift, or just cheer people on! ♥️

Saturday mornings at 6SU are already a favorite. This one's going to be a little different. 💪

On August 22 at 10:30 AM, we're hosting a free strongman workout + info session - led by Josh Marker, Maggie Mollenhauer, and Frank Mirano of Ames Fitness.

And honestly? You don't have to lift a thing to come. Bring a friend. Come watch people try something brand new, cheer them on, and see what all the strongman hype is about.

It's also a sneak peek at APEX Fest - their strength games coming to Ames on September 19, with vendors, food trucks, childcare, and a charity bench press, free to the whole community. Consider this your backstage pass.

Whether you're in the workout or on the sideline, it's the same energy: people showing up for themselves - and for each other. That's what we do best. ♥️🖤

6SU is one of the best places to practice being the best version of yourself.♥️

It demands respect. Stay consistent. Do the tough thing, even when you don't feel like it, and the results will come.

It teaches you self-love. How to face adversity, overcome challenges, and stay disciplined when quitting would be easier.

The way you show up here is the way you show up everywhere — at home, at work, in your own head.

That's what makes this place valuable. It's not about the calorie burn. It's where you get to practice becoming the person you want to be.

The best part of this photo isn't that someone came to the gym.

It's that she didn't feel like she had to wait until she could work out again to come back.

She came to catch up with friends, introduce her new baby, and simply be here.

That's what we hope Sixth Street Underground will always be—a place where people belong.

Fitness brought us together.

Community is what keeps us together. ♥️

Accidentally twinning is the most fun, but honestly, it's no coincidence.

There's something about being in a room full of people all chasing the same thing — getting stronger, committing to themselves, doing the hard stuff together.

Surround yourself with people who make you want to show up. ♥️
