🔥 THE COMMITTED CLUB IS ON FIRE. 🔥

8 months into the year, and we have members who have hit 10+ workouts every single month so far this year.

That's 8 months straight of...

Showing up.
Making training a priority.
Choosing consistency over excuses.
Adjusting schedules when life starts life-ing.

These members know it's not about being perfect, but rather about building a habit, putting in the work, and continuing to show up, month after month.

And then we had a BIG first: one of our members officially hit 150 workouts for the year… with FOUR months still to go!

These numbers are incredible, but what they really represent is commitment, discipline, and a whole lot of work over MONTHS.

To everyone in the Committed Club here at SOS: we see you, we're proud of you, and we're cheering you on. You're not taking short cuts, you're in this whole fitness thing for the long-term and we love it!

Now let's see what we can do with the final four months. 💪

MOVE WELL FIRST.

High-level athletes make everything look easy. And that comes from managing ‘space.’ Learn to create space and take it away for more movement efficiency.

Your athlete doesn't need to train harder all year.

They need to train smarter across the whole year.

If every season is "go time," when do they:

💪 Build?
🔄 Recover?
⚡ Adapt?
📈 Prepare?

That's why we think about the whole year, not just the current season.

In-season → Maintain & perform
Off-season → Build & develop

The priority should shift based on what the athlete needs right now.

And for year-round athletes, this matters even more.

Sometimes the best thing for development isn't MORE.

And usually, it isn't NONE.

It's the right training, at the right time.

Are you a Community-Driven Athlete? MOVE is for you. 🙌

You could train alone—but it's not nearly as fun. You want people who push you, cheer you on, and make every session something to look forward to.

Whether you simply love being around others, spend a lot of time alone because you work from home or are retired, or want to replace your social time with something healthier (goodbye happy hour, hello training!), the SOS community supports your goals while keeping it fun and motivating.

📌 MOVE isn't just a workout—it's a community of like-minded athletes ready to support each other every step of the way.

At some point, fitness becomes less about looking fit in a bathing suit and more about looking fit on lab results.

It becomes less about getting great at training and more about staying capable.

- Carrying luggage.
- Walking 18 holes.
- Playing with your grandkids.
- Recovering faster.
- Staying independent.

We design our MOVE group training programs to help you build strength that makes life feels easier.

Come try a class this fall! (First one is on us.)

Low back pain is incredibly common.

If you've ever experienced it, you know it's no laughing matter. 😫

The good news? Appropriate movement and exercise can play an important role in improving strength, function, and confidence in your body.

A few important notes first:

❌ If you're currently dealing with low back pain, it's important to see a qualified medical professional for an appropriate evaluation and guidance.

✅ If you've been cleared to exercise, we can help you focus on building a stronger, more resilient body.

Here are four areas we often focus on:

1️⃣ Improve soft tissue quality
Foam rolling can be a simple way to prepare your body for movement.

2️⃣ Improve mobility and flexibility
Pay attention to your hips and lower body to help you move more efficiently.

3️⃣ Build strong hips and glutes
Your hips and glutes play an important role in many of your everyday movements.

4️⃣ Develop core strength
A strong core can help you build better control and stability as you move.

The goal isn't to find one magical exercise that "fixes" your back.

It's about gradually building movement, strength, and confidence in a way that's appropriate for you.

Check out the video below for some simple exercises to get started! 👇

Please note: The exercises shown are for general educational purposes and are not intended to diagnose, treat, or cure low back pain. If you are experiencing pain or have concerns about starting an exercise program, consult a qualified medical profes

What if, instead, just for a little while, we simply did our best?

And let the future take care of itself.

Two things: We do it all the time. Constantly. We’re terrible at it. We spend our days guessing how an action will impact the future, and we’re often wrong. And we spend the rest of our…

Most people are solving the wrong problem.

You add more cardio when sleep is destroying your hunger hormones.
You push harder in the gym when you're missing every third week.
You stretch more when the real issue is weakness, not tightness.

More effort in the wrong direction isn't progress. It's just more frustration.

Not sure? Great coaches help you figure out what's actually in the way so you can fix that first.
