As I've gotten older, I've realized something.

Recovery matters just as much as performance.

There was a time when I could push hard, bounce back, and never think twice about it.

But lately I started noticing that some workouts left me more drained than energized.

My sleep, focus, and recovery just felt off.

And what surprised me is how much of that can start beneath the surface, with markers most people never think to check.

Things like magnesium, iron, and even your hormone levels can directly affect your energy recovery and performance.

When they're off, everything feels harder than it should.

When they're aligned, your body responds differently.

That's why I use function.
