Performance Durability — About

A Guide for Time-Starved Professionals Who Refuse to Slow Down

You’re ambitious. You work hard. You don’t need more recovery — you need more capacity.

When your system is trained for pressure:

• You think clearly when others fatigue.

• You recover faster between high-intensity weeks.

• You make better decisions under stress.

• You lead longer, stronger, and without burnout.

This isn’t “executive wellness.” It’s performance insurance for people who can’t afford to slow down.

That’s where I come in.

Meet Your Guide

I’m Mark Perkins — a personal performance coach with 27+ years of experience helping professionals like you build bodies that keep pace with their ambitions.

For over two decades, I coached senior partners and executives at Goldman Sachs.

I saw firsthand how pressure, stress, and poor training advice left even the most disciplined people sidelined with pain, fatigue, and frustration.

I created the Performance Durability system so high achievers could:

• Restore how they move

• Rebuild how they train

• Perform and achieve your best results again and again.

Achieving a Sub-3 Marathon

At 47, I ran the Berlin Marathon in 2:56. The bigger win wasn’t the time — it was the pigheaded discipline and determination it took to make it happen.

For better or worse, how efficiently and effortlessly you move drives your performance.

Old injuries, mobility issues, and a lack of strength and conditioning reveal themselves in how you move.

The Performance Durability Plan

Here’s how we’ll work together:

1. Assess & Restore → Identify what’s holding you back and restore efficient, effortless movement.

2. Rebuild & Train → Layer strength, mobility, and smart endurance training to match your goals.

3. Perform & Sustain → Build resilience so you can train, work, and live without fear of breakdown.

What Success Looks Like

✅ Movement without limits, instead of worrying about the next injury
✅ Building strength that lasts — not just fitness that fades
✅ Showing up with energy at work, at home, and on the start line

You don’t need another cookie-cutter program.

You need a guide who understands the realities of midlife performance — and a system that works with your life, not against it.
