- Ken Shimizu

This photo was taken in 1946.
The guy is Ken Shimizu. He was 35 years old with two children.

Shimizu never ran, never biked, never swam.
He went to bed late, ate whatever he wanted, even drank beer instead of water.
He ate big dinners every night.
What did Shimizu do to get such a body?
Shimizu didn’t have any secrets.

Shimizu is the person sitting in the bottom left corner of the photo.
As for the man standing in the middle, I'm not sure who that is....

Do we live in a hologram? 🤯

Probably not… but our brain might work on the same principles.

Our perception of reality isn’t just what we see. It’s a complex interference pattern of sensory inputs. Light, touch, smell, taste, and sound all combine in our brain, forming a mental hologram that influences how we move, react, and perform.

If we understand how this works, can we optimize it? Can we use this knowledge to maximize performance—whether in high-stakes business meetings or on race day?

Read my latest blog to explore how multisensory interference impacts our training, decision-making, and competitive edge.

"It’s Time for You to Man/Woman Up!"

Executives, let’s cut to the chase: you will never FIND the time to work on yourself—you have to MAKE the time.

Success—whether in business or life—starts with a commitment to excellence. It begins with a vision, a plan, and taking that all-important first step. The ROI of investing in yourself is exponential. It’s not just about personal growth; it’s a strategic investment in your business, your leadership, and your legacy.

When you’re stronger, sharper, and more energized, you’ll transform how you lead, inspire, and perform.

1️⃣ The stronger you are—mentally and physically—the better you’ll elevate your leadership, decision-making, and ability to unleash potential in your team.

2️⃣ You won’t lose time; you’ll gain sharper focus, higher energy, and unmatched performance.

3️⃣ Leaders who prioritize their bodies and minds become a catalyst for change, bringing resilience and inspiration to every challenge.

This is your call to action:

Building a daily and structured endurance regimen—driven by meaningful data, optimized with AI, and guided by experienced coaches—is the key to achieving transformative results in the most efficient way.

Start reaping the benefits now—contact GREAT ENDURANCE TRAINING and learn the lessons from "The Executive Triathlete."

💡 Remember: great leaders don’t just manage time—they maximize it, leaving a legacy of inspiration and impact.

Are you ready to make the move?
