Our first Old School Saturday was exactly what we hoped it would be: hard work, high energy, lots of cheering, and a room full of people willing to show up and give their best.

Fight Gone Bad brought the sweat, but the community brought the magic.

Thank you to everyone who came out, brought a friend, encouraged someone through a tough round, and reminded us why these old-school CrossFit workouts are still so much fun.

We loved seeing members, guests, and CrossFit curious athletes all sharing the floor together.

And because this one was such a great turnout… we’re doing it again.

Fitness is better with community.

On Saturday, June 13 at 9:00 AM, we’re hosting our first Old School Saturday at CrossFit St. Charles, and everyone is invited.

We’ll be doing Fight Gone Bad, one of the classic CrossFit workouts. It’s a great mix of effort, energy, teamwork, and encouragement, and it can be scaled for all fitness levels.

This workout is free and open to the community.

We’re also using the morning as a chance to give back. Bring a canned good or non-perishable food item, and we’ll donate everything collected to a local food pantry.

Come for the workout.
Bring a friend.
Support the community.
Leave feeling proud.

Coach Val gets it.

She knows what it feels like to walk into the gym, try something new, and wonder if you’re ready.

And she also knows what happens when you keep showing up.

Confidence grows. Strength builds. Your body learns what it’s capable of. And suddenly, the things that once felt intimidating start to feel possible.

That’s what great coaching does.

It meets you where you are, helps you move safely, and reminds you that you don’t have to have it all figured out before you begin.

Come train with Coach Val and the CFSTC crew.

Strength doesn’t happen by accident.

It happens when you show up, learn good technique, and put in consistent work over time.

Our new Strength Training classes are built to help you get stronger, move better, and feel more confident under the bar — whether you’re newer to lifting or ready to build on the foundation you already have.

Evening classes begin June 15
Morning classes begin June 17

Come ready to learn, lift, and get stronger with us.

Spots are limited. Message us to get signed up or ask a coach for details.

Curious about CrossFit but not sure where to start?

This is a great day to come check it out.

On Saturday, June 13 at 9:00 AM, CrossFit St. Charles is hosting a free community workout for anyone who wants to move, sweat, and experience what our gym is all about.

We’re doing the classic workout Fight Gone Bad, but don’t let the name scare you. Every movement can be scaled, modified, and adjusted to fit your current fitness level.

You do not need to be “in shape” to come.
You do not need CrossFit experience.
You do not need to know what you’re doing before you walk in.

That’s what our coaches are here for.

Bring a friend, bring a family member, or come solo. You’ll be welcomed either way.

We’re also collecting canned goods and non-perishable food items for a local food pantry if you’d like to contribute.

Things they don’t tell you… It’s way more than just coming to get a workout in.

1. You’ll probably scale most workouts at first and that’s not you “doing less.” It’s doing what’s right for you.
2. It’s way less intimidating than what the internet makes it out to be.
3. You’ll learn more acronyms than you ever expected. AMRAP. RX. EMOM.
4. You’ll start turning up for the people as much as the training.
5. You probably won’t finish some of the workouts, but that’s ok!
6. Competitiveness is what you make it. Some people want podiums. Some want an hour for themselves.
7. CrossFit isn’t just fitness for a lot of people. It becomes structure. Routine. Stress relief. Community. Confidence.
