🚨 COALITION GROUP TRAINING IS COMING THIS OCTOBER 🚨

And we’re doing things a little differently around here.

Brittany Phelps will be leading Coalition Group Training writing the programming, coaching the classes and bringing her strength + high-performance style of training to Coalition.

If you’ve taken Britt’s classes before… you already know what to expect. If you haven’t, get ready.

This isn’t your typical group fitness class.

Think of it like your own gym session the workout is programmed for you, and Brit is there to teach the movements, coach your form, help with weights and modifications, and push you to progress.

🏋️ Strength
⚡ Power + explosiveness
🏃 Athletic movement
🔥 Conditioning
💪 Muscle building

You don’t have to be an athlete to train like one.

And yes, Britt’s favorites are coming too…themed workouts, holiday workouts and the occasional workout that may make you question why you showed up.

🚨 FOUNDERS RATE: $140/MONTH
Lock it in now before spots fill.

Once Founders spots are gone:
Unlimited — $180/month
6 Classes/Month — $160/month

Class times are still being finalized, and we want your input!

And don’t worry — the Coalition you know isn’t going anywhere.

Same 24/7 open gym. Same community. Same incredible coaches. Same 1:1 training. Even MORE equipment coming.

We’re just giving you more ways to train.

Same Coalition. More to come 💯

There’s a lot happening behind the scenes at Coalition, and over the next several weeks, we’ll be sharing some exciting new options for both current and new members. We’re not ready to give away all the details just yet, but we think you’re going to be pretty excited about what’s ahead.

More than anything, we truly appreciate each and every one of you and the continued support you’ve shown Coalition. This community is what makes this place what it is, and we’re excited to keep building on that together.

This is the beginning of a new chapter for Coalition, and there’s a lot to look forward to.

Stay tuned. More announcements are coming soon, and we’re just getting started.

URGENT ATTENTION

Due to a water main break in our neighbors parking lot, Coalition will be forced to close for the rest of the day today.

Without water, we cannot have the bathrooms in operation. Without working bathrooms, we cannot be open.

We will be closed from noon (12pm) on Monday, 8/10 until Tuesday morning. We will reopen Tuesday morning for personal training and regular business.

Sorry for the inconvenience!

They said it couldn’t be done.

They said the cable tower pin was unmovable. That it had claimed better men. That some things simply aren’t meant for us.

Today, one man proved them wrong.

New equipment added to the floor!

Was able to find and snag a Paramount PL2100 seated leg curl. In my opinion this is a super slept on machine, the range of motion and feel on it is pretty excellent. It only has a 170lb weight stack so this is definitely a machine that will require more reps than our Magnum leg curl, but it’s a significant from the Nautilus Nitro that will be leaving soon.

The magnum biangular flat press is in!

This is one of my personal favorite chest pieces, it’s not super heavy but the movement just feels so good. This is a Gen 1 piece, which you can tell by the shape of the handles and lack of a range limiter, which can make it a little tougher to get into, but the range of motion is excellent.

We are always striving to bring the best equipment to the gym!
