Your Best Years Are Still Ahead of You
Your Fitness Age Matters More Than Your Birth Year.
At AgeShift, I blend science with my own journey—from long hours at a desk to natural bodybuilding, tech startups, and work in pharma and biotech. I know what it’s like to feel stuck in your body, drained by work, and unsure how to turn things around. A minimal effective dose of evidence-based training helped me rebuild my strength, endurance, and overall health without burnout. Experts like Dr. Peter Attia have reinforced what I’ve seen firsthand: fitness can often outperform pharmaceuticals when it comes to longevity. If you’re ready to shift your physical age, I’d love to help.
