Who you spend your time with makes a world of difference.

Who are some of your favorite training partners (now or then)? Why?

Shout them out and make plans to train with them again sometime soon. Going solo works in a pinch, but we’re always better together ❤️

Here's what nobody explains about
“trusting the process…”

…the process includes doubt.

…the process includes plateaus.

…the process includes days where you feel like you're going backward.

Those aren't signs the process - or you - are broken. They're part of the process. Trusting it means trusting the most uncomfortable parts, too.

Play the long game. ♥️

Those who stay consistent with training, don’t have more motivation, willpower, or time, and aren’t focused on aesthetics - they’re seeking clarity.

Training isn’t pressure, it’s relief. It’s one of the few places no one needs anything from them. Movement steadies their mind, gives them peace, and helps them come back both physically and mentally stronger.

When movement becomes care instead of correction, when your body is treated kindly, everything changes.

If you’ve always thought exercise was a punishment for how your body looks try training for how it makes your body and mind feel - it’s a game changer.

We can help. ♥️

"If you want the rainbow, you gotta put up with the rain." — Dolly knew. ♥️

You don't need perfect conditions.

You need the ability to find steadiness and take care of yourself while life is still happening.

That's what we train for. 👊

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.

♥️🖤
