🐎🌿 BIG HORSE 5K — WHAT A DAY! 🌿🐎

Beautiful weather, an incredible property, an awesome group of people - and of course… plenty of WET, WILD & MUDDY fun along the way! 😂💪

The grounds at Big Horse Vineyards were absolutely incredible and gave us the perfect backdrop for a Gut Check adventure. We couldn’t have asked for a better morning to get outside, challenge ourselves, get a little dirty, and HAVE A BLAST!

A HUGE THANK YOU to Don & Trinity for opening up their amazing property and allowing us to bring the Gut Check crew out for this special event. We truly appreciate your hospitality and generosity! ❤️

And to everyone who came out - THANK YOU! You showed up ready to run, hike, laugh, get muddy and make some memories. That’s what Gut Check is all about. 🤘

Come run, drink and raise a little hell with us at the annual Big Horse Vineyards 5K! 🍷🏃

This ain’t your boring neighborhood 5K. You’ll tackle a beautiful vineyard trail course with plenty of dirt, hills and just enough suffering to make that FREE w**e tasting at the finish taste even better.

Then stick around for our Charity B**r Mile benefiting LVC Miner Athletics. Go solo or grab a team of 2 or 4. 🍺

There’ll be food available for purchase, plenty of w**e, and at 1PM the Folsom Prison Five/ Johnny Cash Tribute Show takes the stage. You definitely don’t want to miss these guys.

There’s still time to join us! Run a little. Drink a little. Help the kids. Listen to some Cash. Sounds like a pretty damn good day to me.

71 years young… and getting stronger. 💪

When Tommy first came to Gut Check Fitness, he was already active. He golfed, walked, and biked regularly. But he wanted more than just staying active, he wanted accountability, more strength, more muscle, better mobility, and to simply feel his best.

Today, he’s doing farmer carries, sprinting, and moving with a level of confidence that reminds us all what’s possible when you stay consistent.

One of my favorite things he shared was this:

“Nicole is a highly educated and trained professional who knows the body and all its capabilities. Better yet, she tailors every session to improve what YOU want to improve—and the results come quickly.”

Tommy’s journey is proof that it’s never too late to invest in your health. Whether you’re 31, 51, or 71, your body can become stronger, more capable, and more resilient than you think.

We work with clients in person and online, creating personalized programs that meet you where you are and help you get where you want to be.

Your age isn’t the deciding factor. Your decision to start is.

Throw down Thursday!

As much as I enjoy throwing some weight around a couple days a week, nothing beats a good old Gut Check workout. Like this morning’s heart pumping, lung burning, quad shaking hill repeats.

The payoff is always worth it.

Stronger heart.
Stronger glutes.
Stronger mind.

That’s the beauty of Gut Check. The Earth is our Gym.
No machines. No excuses.

Make hill repeats part of your weekly routine. Run them if you can. Walk them if you have to. Just don’t skip them.
Every climb makes you stronger.

Who’s ready to conquer the next hill?

Message from Nicole Decker:

📣To all my ladies out there, the goal isn’t just to lose weight… it’s to build a body that carries you confidently through every season of life.

As a woman over 40, our bodies change. Hormones shift, muscle naturally declines, and our metabolism isn’t quite what it used to be.

The good news? We have more control than we often realize.

Strength training, eating enough protein, daily movement, quality sleep, and consistency are some of the most powerful tools we have to protect our health for years to come.

Lately, there’s been a lot of conversation about GLP-1 medications. They can be a helpful tool for some, but research suggests that when weight is lost without resistance training and enough protein, some of that loss can come from lean muscle, not just body fat.

And muscle matters.

💪 It supports your metabolism.
🦴 It protects your bones.
⚖️ It improves balance and mobility.
❤️ It helps you stay strong, healthy, and independent.

Whether you’re taking a GLP-1, you’ve stopped taking one, or you’ve never considered one…

The foundation stays the same.

✅ Strength train.
✅ Prioritize protein.
✅ Move your body.
✅ Recover well.
✅ Focus on becoming stronger, not just smaller.

As a coach, my goal isn’t simply to help women lose weight.

It’s to help them build strength, confidence, and a healthy body that lasts a lifetime.

If you’re ready to invest in your long-term health, I’d love to help. ❤️

FIRED UP FRIDAY!

The alarm went off at 4:45 this morning, just like it has for the past 30 years. As I rolled out of bed to lead our 6AM Gut Check workout, I caught myself asking, “Why do I keep doing this?”

Trust me, I don’t love early mornings either. I’d much rather stay in the ole fart sack.

Then I looked in the mirror.

I still wear the same size jeans I did when I graduated high school. I can run, swim, hike, and chase adventure anywhere in the world. I take no meds. I have the energy to keep doing epic s**t.

That’s why I get up.

Every workout is an investment in tomorrow.

Health and fitness is the closest thing we have to a fountain of youth. And it’s never too late to start investing in yourself.

Set that alarm tomorrow morning. Your future self will thank you.

HILL DAY.

Want stronger legs, better cardio, a tougher mindset, and buns of steel? Run hills.

The hill doesn’t care if you’re a world champion, a soccer mom, a retired US Army Vet or the guy who swears he used to be in shape. It humbles everyone.

Sure, your lungs will be screaming and your legs will be on fire, but that’s where good stuff happens.
Besides, nobody ever got tougher standing at the bottom of a hill. Or playing dead in the parking lot like the crew below.

Remember, if you need help putting together a program that includes hills, stairs or similar, a Gut Check Fitness coach has got you covered.
