The 740 Challenge

7 Habits. 40 Days. Transforming Every Day.

Day 8: Why I’m Still Walking (And Why You Should Too)

Seven days down. One week of perfect execution.

This morning I laced up for my walk thinking about something unexpected: I never saw this coming.

When I was younger, walking was what old people did. Real exercise meant running, lifting, sweating buckets. Walking? That was just… transportation.

At 47, walking is one of my favorite parts of the day.

Not the lifting (though Workout B yesterday destroyed me in the best way). Not the yoga. The walk.

Here’s why that matters for the 7-40 Challenge: Simple works. Sustainable beats intense.

Hippocrates said it 2,000 years ago: “Walking is man’s best medicine.” He was right then. He’s right now.

Three reasons walking wins:

Fresh air. Whether it’s scorching summer or crisp winter, stepping outside and filling my lungs pulls me away from screens and routines. It resets my energy in a way indoor workouts can’t match.

Audiobook time. I’m working through “Made to Stick” while walking. Physical movement + mental input = how I learn best. Double productivity.

My brain needs motion. I’m still that energetic kid who thinks better while moving. At 47, I feel it every time—blood pumping wakes up my brain. Nietzsche nailed it: “All truly great thoughts are conceived by walking.”

The practical magic: Walking is low-impact. Easy on joints. No jarring bounces or overuse injuries. It strengthens your heart, aids weight management, releases endorphins that lift your mood. And it’s accessible—no gym required, no equipment needed.

Just shoes and intention.

I never thought I’d be the guy who loves his daily walk. But here I am, Day 8, proving that the best habits are often the simplest ones.

The best time to start walking? Now. Not when you’re “in better shape.” Not when the weather’s perfect. Now.

Lace up. One mile. See how you feel.

Day 8 Scorecard: ✅ Bible study ✅ Exercise (walk + more today) ✅ Reading ✅ Water, calories, gratitude ✅ Creative hour

Eight consecutive perfect days. The simple habits stack.
