This is the backbone of the Grindstone system — intelligently structured strength training built for bodies that have put in the work.

  • 4–5 day training split built around joint health, controlled tempo, and quality movement
  • Built-in progressions to restore mobility, strength, and confidence
  • Recovery Track PDF included each week for mobility, breathwork, and restoration
  • Balanced conditioning to maintain power and stamina — without grinding your body down

Train with purpose. Recover with precision. Move better than you have in years.

  • Designed for Men & Women 40–65+
  • Built-In Support, Structure, and Coach Guidance
  • Workouts in 45–60 Minutes — Real Training for Real Life

Grindstone Longevity gives you the tools, structure, and philosophy to keep doing what you love — for the rest of your life.

We've said it before- this is more than just a workout program, it's a complete lifestyle system. We designed systems and protocols to help you in every aspect of your health and well being, from the brain to the brawn. See the complete system below.

Start today

You’ve spent years building strength, discipline, and grit.

Now it’s time to make that work for you — not against you.

Grindstone Longevity is more than a training program — it’s a lifestyle guide designed for men and women who want to keep performing, feeling, and living at their peak, well into their 40s, 50s, 60s, and beyond.

Crafted by veteran coach Glenn, this program is the culmination of 35 years of experience — lessons learned from victories, setbacks, and everything in between. It’s built on the principle that what we do today has a tangible effect on how we live tomorrow.

This is for the serious, committed individual who’s ready to extend their lifespan, optimize their performance, and live every day with the energy and mindset of “Let’s go.

Longevity isn’t slowing down — it’s staying capable, powerful, and ready for whatever life throws your way.

"Things don't happen by accident. It's the 1% growth in all areas of life that lay the foundation for success."

PROGRAM FAQs

WHO IS GRINDSTONE LONGEVITY FOR

Men and women who still love to train but want to do it smarter — not harder. Perfect for the 40–65+ crowd or anyone who wants to stay strong, mobile, and resilient.

WILL I GET STRONGER

Absolutely. You’ll build real, functional strength — with intelligent programming that protects your joints and optimizes recovery instead of burning you out.

HOW LONG ARE THE WORKOUTS

Most sessions are 45–60 minutes, including warm-up and recovery protocols. Time-efficient, effective, and designed to fit your life.

WHAT IF I'M INJURED TO HAVE JOINT ISSUES

That’s exactly who we built this for. Controlled tempos, smart loading, and intentional mobility work make it perfect for rebuilding strength safely.

IS THIS FOR WOMEN TOO

Yes — longevity doesn’t discriminate. Every session, food guide, and tracker is built for both men and women to scale to their individual needs.

CAN I COMBINE THIS WITH OTHER PROGRAMS
