I routinely spend four+ hours in Zoom meetings Monday through Friday, followed by an hour of clearing emails, followed by chasing my kids around & making dinner, doing bedtime, and then sitting on the couch to decompress.

Sometimes… by the time I stood up to head to bed, my lower back feels like I borrowed it from a 300 year old tin man.

If you are a dad with a desk job, you aren't lazy, you're paying a literal physical tax.

Sitting for 8+ hours a day forces your body to adapt to a fixed, constrained posture, causing your kinetic chain to flatline - which… is fun.

It’s certainly different from active college or post-grad days when responsibilities were a mere suggestion vs reality.

As we head into our 30s & 40s, it’s time to shift away from “hell yeah, 6 pack abs!” to more of a desire to build a resilient chassis that can withstand the biological degradation of our stationary life.

So… let’s start with thing number 1. How to not have a shrimp neck after staring at a screen for 8 hours ‘earning a living’.

⚡ MOVEMENT: The Cervical Reset

Prolonged screen use pulls your upper back into excessive flexion and forces your head forward (i.e. shrimp).

This position, called a "cervical shear" adds an extra 10 to 12 pounds of effective weight to your spine for every single inch your head protrudes (woof). Over time, it causes connective tissue deformation and makes it REALLY HARD to get your posture back.

Good news, it’s fixable.

The 120-Second Fix: Drop what you are doing right now and complete 2 sets of 15 slow Cervical Chin Tucks against your office chair or a flat wall.

How? Pull your head straight back like you're making an aggressive double chin, then relax and repeat. It immediately resets the cervical spine, engages dormant stabilizers, and stops the lower back from overcompensating later.

🥩 FOOD: Overriding Anabolic Resistance

To help maintain the muscles responsible for keeping this posture (and about 3,000 other things), let’s eat properly, yeah?

In your 20s, you could maintain muscle mass on a diet of cheap carbs and intermittent protein (hellooooo Ramen).

In your late 30s and 40s, the aging muscle architecture triggers "anabolic resistance", a state where your skeletal muscle exhibits a blunted response to protein uptake. The "dimmer switch" of muscle protein synthesis (MPS) turns down.

To bypass this metabolic hurdle, traditional base guidelines are completely insufficient.

What to do: You need to hit a threshold of at least 0.4g/kg of high-quality protein per single meal to trigger the mTOR pathway and force muscular repair. Anchor your next meal with a minimum of 35–40 grams of bioavailable protein (like 4 whole eggs or a clean whey/Greek yogurt base) to clear the critical leucine threshold.

Or, in english, help you recover & keep that musculature longer.

📊 METRICS: The Sit-Rising Test (SRT)

Fitness and health can be amorphous. So in this series, we’ll be talking about really binary metrics, tests, ratios, etc. that can be measured, analyzed and improved, to give you a sense of your progress on a road to longevity.

The first is a fun test called the Sit-Rising Test (SRT)

Forget checking your baseline purely by how much you can bench press (even though it’s so fun). True body durability is measured by functional autonomy and systemic balance, i.e. how much can you do on your own without help.

A score below 8 indicates a significant reduction in joint flexibility, core coordination, and lower-body force production, correlating with a spike in functional mortality risk over a 10-year horizon (which, nobody wants)

If you need to use your hands to get up off the floor with your kids, your system is giving you an early warning sign.

Hit reply and let me know your baseline score. No judgment, just some data to see where we take things from here.

Up next, we’ll uncover the truth about cardio, the difference between ‘good and bad’, and the metric to track to see if your heart is responding as it should

Until next time,

One final thought for the week

Everyone measures fitness differently.

A good friend, years ago said to me “to me, it’s wiping my own a** as long as possible.

Which, while silly, speaks to a desire for true, lasting independence.

Do what you want, by and for yourself, for as long as you can.

Run with your grand kids at 80.

MEET your great grand kids at all… and still be able to run circles around them.
