Spartan Super in the books!

The slopes and trails at Massanutten are no joke!

Happy with how I did on the obstacles, many felt so much easier to do than two years ago. Just need to get my trail and mountain legs back😁

Was also a blast running with 4 guys who haven't done a race yet, helping them and seeing them have a lot success today👊

Sprint on tap for tomorrow! AROO!

Starting off the weekend strong with a strength workout and run with the crew, capped off with Americano!

How are you spending your weekend?

We hear this all the time.
Someone tweaks their back at the gym or during a run and suddenly stops everything out of fear.

They’re told to “rest,” “ice it,” or “just take it easy.”
But here’s the truth: most people aren’t injured — they’re just hurt.

Hurt means your body is sending a warning sign.
Injured means there’s real damage that needs a plan.

At Function 4 Life, we help you figure out which one it is — fast.
Then we show you exactly what to do next:
✅ The movements to keep doing.
✅ The ones to avoid (for now).
✅ The tools to actually get better — not just mask pain.

Because guessing wrong can mean the difference between a few days of soreness…
and months of setbacks.

DM us the word HURT and we’ll help you figure out what’s really going on — and how to get back to moving with confidence.

Top 3 Things to Ensure a Successful Marathon

1️⃣ Train Smart, Not Just Hard
Consistency beats mileage. Build gradually, include recovery runs, and don’t ignore strength work.

👉 At Function 4 Life, we include custom strength training mobility drills and muscle therapy so your body can handle the miles — not just survive them.

2️⃣ Fix the Root Cause of Pain Early
Nagging knee, ankle, foot, hip, or back pain? It’s rarely just where you feel it.

👉 We identify the true source through movement analysis and hands-on assessment, so you stay injury-free all season.

3️⃣ Dial In Recovery
Sleep, nutrition, and mobility work are your performance multipliers.

👉 We guide you through active recovery strategies and individualized mobility work to keep you feeling fresh mile after mile.

💥 Whether it’s your first marathon or your fastest, Function 4 Life helps you train, move, and recover the right way — for a stronger finish and a healthier body.

One runner came to us frustrated.
He’d been foam rolling his IT band, hammering his quads with a massage gun, stretching, and strengthening his glutes for months.
But every time he ran more than a few miles, that same sharp ache showed up on the outside of his knee.

He thought it was a knee issue.
Turns out — it wasn’t.

The real problem? His lower back.
The pain was being referred down the chain.
And because no one ever looked at the root cause, he was chasing the wrong problem the whole time.

After finding us on Instagram, we built him a plan that actually addressed where the pain started — not just where he felt it.
On Saturday, he ran his first half marathon pain-free.

DM us the word RUNNER if you’re tired of chasing symptoms and want to finally find the root cause of your pain.

Several photos from the race on Saturday of the Function 4 Life team taking care of some runners after they crushed the course!

All of them had PR times!

Post race though, they had 4 key areas that were bothering them that you don't want aches, pains or stiffness hanging around. So kudos to them for addressing it ASAP.

The lower back, hip, knee and calf/achilles can hinder not only your performance, but your everyday life.

Like this post and share it with your running buddy who is sore today!

Happy Sunday! A short poem that somes up the weekend perfectly for me.

Good Weather, Good Times

The sun's out laughing, the sky's so wide,
Why stay trapped when there's fun outside?
Grab friends, grab family, lace up your shoes,
Run trails, hike hills, chase those views

Skip the couch, it can wait till night,
Let fresh air win, it feels just right.
Move, laugh, explore, let worries slide,
Life's best lived on the sunny side.

Resonate with anyone?
