Sean turns 40 today. We celebrated with a “40th birthday workout”: see below x 3 rounds. Perfect choice for 40s - strength, mobility and endurance.
Why? Because fitness at 40 isn’t just about performance—it’s prevention.
👉 Longevity is built in decades, not days.
👉 Your 40s are the checkpoint: strength, aerobic fitness, and yes—even cancer screening.
Happy birthday, Sean. Here’s to stacking the odds for another 40.

Ozempic. Wegovy. Zepbound. Everyone’s talking about them. But should you be on one of these medications?

Your heart skips, flutters, or races. Should you worry?
Most of the time, no. Swipe through for how I work it up in clinic, what we usually find, and when to get seen right away.
The full article is linked in my bio. Save this for later, or send it to someone whose heart keeps skipping.

Two devices. Same person. Same nights.
Oura Ring: 57 minutes of deep sleep. Whoop: 128 minutes.
Which one is right? Neither, probably.
Last week Katie and I raced a triathlon, drove 15 hours round trip with four kids and a 34-foot trailer and worked full clinic days. We wore four wearables the entire time.
Our sleep scores said Good. We felt grey.
The score captures what happened between the sheets. It cannot capture what you brought to bed with you.
New article is live. DM me for link.

Your handshake might be telling you more about your heart than your cholesterol panel 👀

Grip strength is one of the strongest predictors of heart health and longevity, and most people have never tested theirs. Studies on hundreds of thousands of people show that low grip strength is linked to higher risk of heart attack, stroke, and early death. It even out-predicts blood pressure.

The good news: it's one of the easiest things to improve. Swipe to see what your grip says about your health and how to build it. 💪

Most heart attacks in your 40s don’t begin in your 40s.

They begin quietly in your 20s and 30s.

No dramatic symptoms.

Just:

Cholesterol particles rising.
Insulin creeping.
Fitness declining.
Blood pressure drifting.

Nothing feels urgent.
Until it is.

The good news?

This process is measurable.
And modifiable.

If you’re between 30–50s, even 60s, this is your window.

Measure what matters. by @jakekellymd

There are moments when you realize you’ve quietly crossed a line.

Not overnight.
Not dramatically.
But slowly through writing, thinking, listening, and paying attention.

For years, writing was how I processed medicine, training, family, and life. Lately, it’s become something more intentional.

This piece and this image mark a transition.
From accumulation to clarity.
From proving to purpose.
From writing for approval… to writing for meaning.

I write:
• for myself, to think clearly
• for you, to share what I’ve learned
• and for them, so my kids someday understand what mattered

This isn’t an ending.
It’s a hinge.

Grateful for everyone who’s been reading, questioning, and walking alongside me as this evolves. by @jakekellymd
