Aging and mobility don't really go together... I'm learning this the hard way at 42 😬

But feeling good and staying healthy are important so I'm making it a priority. Here's the 6-step process to stay loose, supple, and mobile as we age: https://t.co/669GU9K0Om

Happy Global Running Day!

Let's celebrate what it gives us: memories, friends, accomplishments, and the feeling of speed.

Running has molded my entire life and I wouldn’t have my kids, my best friends, or my business without it!

Here’s to another 28 years of adventure!

[Jason Fitzgerald @JasonFitz1]

In 2005, my XC coach told me something that altered the direction of my running career.

He said, "Start believing me when I tell you how good you can be."

When a coach believes in you, it lights a fire under you. I went on to have the best year of running in my entire life.

[Jason Fitzgerald @JasonFitz1]

I do the same thing in Team Strength Running (affordable coaching for any runner)

This Global Running Day, use code GRD for a 30-day free trial https://t.co/1C2st3Ksgy

“I’m happy to say that I PR’d by 1:40 in my marathon. The best part was that I remained injury free.

“I feel better and stronger than ever. Thank you for making running easier. Your plan gave me a strength that I didn’t know I had or was capable of!” - Liz

[Jason Fitzgerald @JasonFitz1]

@JWLevitt lol i forgot to add context with that. That's how many years I've been running!

[Jason Fitzgerald @JasonFitz1]

@Orbifold78 Correct

Exciting! Looks like natural EPO production increases with post-exercise ketones 💪🏻

[Brady Holmer @Brady_H]

Huge new study showing post-exercise ketones enhance the vascular/angiogenic response to exercise.

Post-exercise ketosis (using @ketone):

• increased femoral artery blood flow by up to 37% and muscle reoxygenation rates by 9%.
• upregulated mRNA markers of angiogenesis and vascular integrity, (e.g., VEGF).
• increased EPO concentrations by 15% at 7 hours post-exercise (effect was additive to the stimulus provided by hypoxia).

Also notable was a significant reduction in the vasoconstrictor endothelin-1 (ET-1) and the stimulation of AMPK and PGC-1α pathways w/ ketones.

@bradford_hardin The dosing is wild (and $$$$)

[Jason Fitzgerald @JasonFitz1]

@tckahler Very cool! And nice work with the short shorts 🤜🏻🤛🏻

[Jason Fitzgerald @JasonFitz1]

@max_stoneking Great advice.

I usually settle on, “Here’s the intended plan - this is your North Star. But just do the best you can and try to adhere to the spirit of the plan. 1-2 weeks of reduced training is no big deal”

[Jason Fitzgerald @JasonFitz1]

Great use of AI for runners

[Jonathan Levitt @JWLevitt]

I analyzed 8 years of my running data with Claude+Strava MCP+my training log and one question: does life stress make me slower?
No. It just makes the same pace cost 10 more bpm.
Stress hides in your heart rate, not your splits.
Fascinating.

@profesormesser @Brady_H 🙏🏻

Brady always brings the thunder!

When @Brady_H comes on the podcast, you get on the podium 💪 https://t.co/Ez01le4R6o

We spend so much time training our bodies... but do you focus on the most important muscle of all: your brain?

A healthy mindset can unlock PR's, increase mental toughness, improve confidence, and boost positivity.

In a sport as hard as running, it pays to train your brain.
