Hey friend,

A friend recently came to me with a problem I hear all the time: he wanted to start a new venture but still be a great dad and husband to his family.

I've wrestled with this before, and it's made me come up with something that I call the 2 Constraint Theory.

When designing your life, focus on two things:

Constraint #1: The single biggest thing blocking you from your goal.

Constraint #2: A counter-constraint that keeps you anchored to your values.

Most people attack their goals and go all in without setting any limits or guardrails.

Often, when they get there, they achieve it, but at a cost they didn't see coming. This could be the marriage that frayed, or kids who barely remember you being around, or the health that quietly deteriorated.

From my experience, a great life isn't just about removing obstacles, it's about choosing the right ones to keep.

Fix the constraint that's holding you back, but protect the constraint that makes life worth living.

That's the game.

Here's what caught my attention this week.

Here Is Your 4 Minute Friday:

1. A $10 Supplement Might Slow How Fast You Age

Most longevity supplements cost a fortune. This one costs less than a lunch.

A new randomized trial from COSMOS tested whether a daily multivitamin could slow biological aging, as measured by epigenetic clocks.

These clocks don't measure how old you are. They measure how fast your cells are aging.

They found that people taking a basic multivitamin (Centrum Silver) showed a measurable slowdown in their biological aging rate over two years. The effect was strongest in people who were aging fastest to begin with.

Now, the effect was modest, and this was an older population. We don't know if this translates into people in their 30s and 40s, but something I realized with coaching thousands of clients is the fact that many of them are not eating the perfect diet.

They also come with a good amount of nutrient deficiencies. While a quality multivitamin isn't a magic pill, it will help the average person plug the nutritional gaps.

And this could be enough for someone to live a longer life.

2. The One Workout That Actually Trains Your Arteries

Most people do HIIT to burn fat or improve fitness. Turns out it's also doing something important inside your arteries.

A recent meta-analysis found that HIIT improves flow-mediated dilation by about 4% better than exercise and moderate cardio combined.

The reason comes down to shear stress. When you push hard, blood moves through your vessels with a force 2–4x higher than at rest.

That pressure appears to be a potent signal for arterial remodeling, essentially training your blood vessels the same way lifting trains your muscles.

Your heart is more than a pump. It's part of a system, and that system responds best to intensity

One hard session a week is enough to start.

❤️ My Favourite Thing This Week

I have a sweet tooth, but I'm doing my best to stay away from most processed sugars, except for this one.

Out of all the artificial sugars that are out there, monk fruit seems to be the most beneficial, with early research showing that it may improve insulin sensitivity and blood sugar.

Now, mind you, I take this in small amounts, and I put this in my protein ice cream or my Greek yogurt breakfast.

I've found that it is a great way to add sweetness to your meals without all the other nasty stuff that comes along with it.
