Built from experience, not trends. For people over 40 who plan to stay strong, capable, and independent for decades.

This is the work I care most about.

MetaFlex is the result of years spent testing what truly works for adults over 40. It’s not trend-based—it’s sustainable, proven, and built for long-term strength, metabolic health, and capability. This is the system I live by and teach everywhere I go.

👋 Hey, I’m Zane

🔥 Creator of the MetaFlex Method & the Fit Over 40 Framework

For more than 25 years, I’ve helped men and women over 40 rebuild their metabolism, regain their energy, and stay strong, lean, and capable well into the second half of life.

I started my career as a personal trainer in 1998 — long before biohacking became a buzzword and before most people understood how deeply strength training, nutrition, recovery, and hormones affect long-term health.

What I saw early on was this:
the strategies that worked in your 20s and 30s stop working the same way after 40 — and pushing harder usually makes things worse.

Over time, I developed what is now known as The MetaFlex Method — a simple, science-backed system designed to preserve muscle, optimize hormones, reduce metabolic dysfunction, and extend both healthspan and performance.

This isn’t built on trends or extremes.
It’s built on what actually works in real bodies, with real lives, and real responsibilities.

Today, I host the Healthy A.F. / Healthy After Fifty Podcast, speak at events across the country, and coach inside the MetaFlex Community, where I help people master the daily habits that create lasting strength, resilience, and freedom.

My focus is simple:
To
help people rebuild metabolic health and high performance by flipping the script on diet and fitness culture — using a fully fueled strategy that reduces metabolic stress, reverses insulin resistance, and restores real energy without restriction, fasting, or burnout training.

  • Restore energy, focus, libido, and sleep

  • Build lean muscle without burnout or overtraining

  • Improve hormones, resilience, and long-term vitality as you age and more!

With a keen eye for detail and a passion for health, Zane empowers individuals to transform their lives through fitness. He is the epitome of excellence in the fitness industry!

"His expertise brought a fresh perspective and pushed my boundaries in ways I hadn't anticipated"

"As a lifelong athlete, I thought I had my fitness regimen down to a science.  But as I've gotten older, it's become more and more difficult to maintain progress, let alone achieve new goals.  That was until I started working with Zane.  His expertise brought a fresh perspective and pushed my boundaries in ways I hadn't anticipated. His program not only emphasized my strengths but also got me doing things I would never do on my own. Zane's guidance extends beyond the gym, offering nutritional advice that enhanced my performance and recovery.  Now in my 40's and two years into training with Zane, I've reached new fitness goals, remained injury free and am setting record times in races that I haven't seen since my late 20's.  To anyone looking to elevate their game, I highly recommend Zane. His dedication and expertise has been pivotal in helping me achieve and surpass my fitness goals." - Adam Sansiveri

"I am 55 years old and, quite honestly, in the best shape of my life."

Zane has been my personal trainer for over 13 years. During this time, my workout routine and diet have changed accordingly, which is one of the many things I appreciate about Zane's training. He doesn't get "stuck". He is constantly doing research about how to achieve the best health possible, no matter your age. He truly wants to help people live their best lives and be as healthy as possible.

I am 55 years old and, quite honestly, in the best shape of my life. I may have been thinner in my younger years, but I definitely wasn't stronger. Developing muscle mass is not easy at 55. Zane has taken the time and energy to perfect my strength training routine and eating habits so that I can retain muscle mass, even as a 55-year-old female. -Stacy Brickell, Ph.D
