For as long as I can remember, I’ve been driven by one question: What does it take to perform at your best—physically, mentally, and emotionally?

That pursuit defined my 16-year career in the NFL. Every day, I trained not just to play the game, but to master every aspect of performance—strength, recovery, focus, and endurance. But over time, I learned that the real foundation for greatness isn’t just how you train… it’s how you fuel your body.

Working with world-class nutritionists, trainers, and doctors, I discovered the critical link between nutrition and performance. The right fuel doesn’t just power your body—it sharpens your mind, balances your energy, and helps you bounce back stronger. It’s the difference between simply showing up and showing up ready to win.

When I retired from football, I knew I wasn’t done competing—but my new mission was different. I wanted to help others unlock that same level of vitality and confidence I had experienced through proper nutrition. That mission became Nutrition53, and from it came our flagship product—Lean1.

Lean1 was created to be more than just a protein shake. It’s a clean, smart, complete meal replacement designed to fit into real lives—the early risers, the go-getters, the parents, the athletes, and everyone in between who refuses to settle for average.

Every serving of Lean1 is built around one purpose: to help you feel better, move better, and live better. With premium proteins, essential nutrients, antioxidants, and natural ingredients that support metabolism and recovery, Lean1 fuels the active, healthy lifestyle we all strive for.

Because living well isn’t about perfection—it’s about consistency, balance, and intention. It’s about showing up every day with energy, focus, and purpose.

That’s what I mean when I say: Live Like You Mean It.
