I was a gym rat growing up, and honestly, it helped shape who I am today.

I want the next generation to have that same opportunity.

“Back in my day”…

The gym wasn’t filled with people staring at their phones. It wasn’t about selfies, followers, or creating content. It was a place to burn off stress, work through problems, build confidence, and learn that results are earned.

That’s what is still about.

I want students to experience that.

Usually, the biggest barriers are cost and time.

Well, the good thing about owning the gym is I can do something about both.

Our unlimited membership is normally $199/month. For high school and college students, I’ve made it just $99 for the entire summer.

Not $99 per month.

$99 for June, July, and August.

Most camps cost more than that and only last a week.

This gives students 3 full months of access to all our classes, including Saturday Barbell Club, weekday classes, coaching, mentorship, and a positive community. Plus, every hour we’re open is Open Gym.

Time isn’t the excuse anymore.

Instead of complaining about students spending all summer on their phones, I’d rather create an opportunity for them to do something different.

Something that could impact them physically, mentally, and socially for years to come.

If you know a high school or college student who could benefit from this, please share it with them.

Let’s help more young people discover a love for fitness, training, and community.

17 years.
17 Murphs.

And today just reminded me what actually makes this place special.

Yeah, we train hard.
Yeah, we push ourselves.

But the real win is that this has become a place where people can come together, bring their friends, bring their family, and just do life together for a few hours.

Because life moves fast.
Most days are just work, responsibilities, errands, repeat.

And somewhere in the middle of all that, people lose connection.

That’s why this matters.
Not just the workout.
The conversations after.
The shared suffering.
The laughs.
The conversations.
The group photos.
The feeling of belonging somewhere.

A place to hangout.
A place to reconnect.
A place to build relationships.

That’s what makes this community special. ❤️

“Different goals. Different trade-offs. Both valid. Choose what serves your life.”

When I was younger, being “gym strong” was the goal.
More weight. Bigger lifts. Better workout scores. Bigger physique.

And there’s absolutely nothing wrong with that.

But as I’ve gotten older — and especially coaching more athletes — my definition of performance changed.

I don’t care as much about carrying extra muscle just to perform better inside the gym anymore.

For me and many of my athletes, that extra size comes with trade-offs:
More food required.
More stress on the joints.
More wear and tear on the system.
Less agility.
Less endurance.
Less freedom of movement.

At some point, you have to ask:
“Strong for what?”

For bodybuilding?
For CrossFit scores?
For longevity?
For sports?
For life?

There isn’t one right answer.
Just consequences and trade-offs to every direction.

Train intentionally.
Not emotionally.

If this peaks your interest, I’m sharing the formula this Sat to help more people at once. 5/16 Sat 8am/9am. If you can’t make that and want in the month rebuild program, DM me.

Keep evolving!

Not Golf, Just Long Drive for Athletic Power Training in 2026

Next year, it's all about sports training. Being able to be athletic for all sports specific demands. Being "Fit" is very different from being Athletic.

I picked Long Drive to test rotational power and speed.

Through all of my research, aka coaching for 16 years, all roads of injuries and chronic pain leads to poor movement mechanics. That's the root cause but when it comes to the fix, gym or PT exercises don't cut it. We'll save that for another day.

Instead of quitting or giving up later in life, I'm going to attack what most people are afraid to do. Being 41 and many people I train are over 50, I feel like we have so much more if we trained differently.

Sprinting, playing hockey, violent swinging like long drive, basketball, jiu jitsu, wrestling, judo, running, are just some of the sports I'm going to be doing next year.

I'm on a mission. If you're interested in this, let's chat. I might take a small group with me.

Fox and I had a great day getting into the Halloween 🎃 Spirit. He also did great carving his pumpkin too!

There’s something about being around fun and positive people that makes life GOOD.

Tired of getting injured lifting? Don’t know where to start or restart?

We have a unique approach to teaching Barbell lifts where we pair movement mechanics with lifting techniques. Whether the goal is longevity or performance, you need both to be optimal.

You think you’ve tried it all but maybe not. Give it a go one more time. Maybe you’ll finally figure out the answers to your lifting problems.
