Community is what's missing from your workout routine.

You already know what to do. Move more. Lift more. Recover. Eat better. The information is everywhere.

And yet.

It's not a willpower problem. It's a support problem.

It's the difference between grinding alone and being surrounded by people who actually want to see you succeed, who understand that hard things are worth doing, and who show up to do them with you.

If your progress has stalled, the missing piece probably isn't a new program or a different diet. It's the people in the room with you.

Your first class is free. Come see what we're building.

We're so back baby.

Murph on Memorial Day is like fireworks on the 4th of July. We love it, we celebrate it, and we work out hard.

And performing Murph alongside your friends and fellow athletes is the best way to spend the day.

Classes on Monday May 25:
7:00 a.m. | 8:30 a.m. | 10:00 a.m.

Brunch potluck to follow. Bring a dish, stay awhile.

One more thing: we have a secret sponsor this year.

Details coming soon. 👀

Tag someone who's doing it with you.

Kenny doesn't have an off switch.

Whether it's his business, his cars, his kids, or the barbell in front of him, he shows up the same way every time. Locked in, full effort, no shortcuts.

That's the standard he sets every time he walks through our door. And it raises the bar for everyone around him.

Be like Kenny.

Have you signed up for class yet?

To the moms who show up before the rest of the house is awake.

You fit training in between school drop-offs, work, meals, appointments, and everything else nobody sees.

You do it because it makes you better at all of it.

Today we celebrate every mom in our gym.

The early birds, the lunch hour regulars, the ones who come in tired and leave strong.

You set a standard for your kids without even trying to.

We see you. We appreciate you. We're proud of you.

Happy Mother's Day.

Kyndall qualified for CrossFit Semifinals and this Saturday, she's finishing it out right here at Arnold CrossFit.

Semifinals is one step from the CrossFit Games.

One. Step.

And she earned her way there through months of work, consistency, and not backing down when things got hard.

We've watched her grow as an athlete and it never gets old seeing someone put in the work and have it pay off like this.

After the 8:30 am class on Saturday, stick around. She'll be performing her final semifinal workouts and we'd love to have the whole community there to cheer her on.

This is exactly what this place is built for. Come out, make some noise, and let her know what Arnold CrossFit is made of.

Murph. Monday, May 25. Memorial Day.

We honor Navy Lieutenant Michael Murphy by doing the workout he loved:
1 mile run
100 pull-ups
200 push-ups
300 air squats
1 mile run.
All while wearing a 20 lb vest if you've got one.

Lt. Murphy was killed in Afghanistan in 2005 protecting his SEAL team. We do it every Memorial Day because the discomfort is the point. One hour of effort to remember a life given.

Three heat options so everyone gets in:
7:00 AM
8:30 AM
10:00 AM

Potluck right after. Bring something to share.

Memorial shirts are being ordered. Last day to buy is end of day Monday the 4th, available in your Wodify app. Grab a coach if you have any issues.

Scaled, partitioned, partnered, full Rx, vest or no vest. Every version counts. Show up, move with intent, eat together.

This week had it all.

Heavy barbell work. Long aerobic efforts. Intervals that tested your engine. Gymnastics, Olympic lifting, odd objects, jumps.l, and more.

That's the point of CrossFit. You don't specialize in one thing. You train everything, nothing catches you off guard.

Our members showed up and worked across every demand we put in front of them. That's not easy. That's the standard we hold here.

Be proud of what you put in this week. Rest this weekend, recharge, and we'll see you Monday ready to go again.

Not every workout needs to leave you on the floor.

Yesterday's session was two things: heavy back squats for sets of 8, then a max effort set of wall balls. No time cap. No chaos. Just load the bar, squat with intent, then find out where your wall ball fitness actually sits.

Strength adaptations require a strength stimulus. Aerobic capacity requires an aerobic stimulus.

Not every session can serve both at max intensity, and trying to force it usually serves neither. Yesterday was about quality reps under load and an honest baseline, not redlining.

Don't worry. The puddle is coming later this week. 😏

Ready to give us a try? Your first class is still free.

New week. New slate.

You made the choice to show up before it got hard. Before the week asked anything of you. That matters.

The people in your life notice what you model. Your kids, your team, your training partners.

Consistency isn't loud, but it's visible.

Get in. Do the work. Carry that into the rest of your week.
