Why Intensity Trumps Duration

By PJ Glassey / / Comments Off on Why Intensity Trumps Duration

The Endothelial Edge: Why Intensity Trumps Duration for Cardiovascular Longevity As an anti-aging researcher, exercise physiologist, author, and inventor of the X Gym exercise methodology, I have spent decades perfecting a 21-minute protocol designed to maximize physiological adaptation. The mainstream often pushes “more is better” regarding exercise volume, but the molecular data suggest a different…

How Vigorous Exercise Fights Cancer

The Mechanical Shield: How Vigorous Exercise Triggers Apoptosis in Circulating Tumor Cells As a functional medicine researcher and inventor of X Gym’s high-intensity training system, I have spent decades analyzing how we can optimize the human machine to resist the diseases of aging. While many focus on the metabolic or hormonal benefits of exercise, there…

Spike Protein Mitigation and Vascular Integrity

By PJ Glassey / / Comments Off on Spike Protein Mitigation and Vascular Integrity

Counteracting the Cumulative Burden: How X Gym Methodology Protects Vascular Integrity As a functional medicine researcher and biohacker, I have spent significant time analyzing the data surrounding spike protein persistence and its role in chronic inflammation. We are seeing spike protein persisting up to 3 months after a COVID infection, and indefinitely after an mRNA…

Your Brain and Your Mind are Different Things

By PJ Glassey / / Comments Off on Your Brain and Your Mind are Different Things

Beyond the Wires: Why Your Brain Isn’t Running the Show (And How That Changes Everything) Do you ever catch yourself saying, “My brain just loves this song,” or “Ugh, my brain’s fried after that meeting”? We toss around these phrases like confetti, but what if I told you they’re not just sloppy shorthand—they’re quietly selling…

The Underestimated Power of Vigorous Exercise

By PJ Glassey / / Comments Off on The Underestimated Power of Vigorous Exercise

Science Got it Wrong: New Data on Intensity Rewrites Longevity Guidelines For decades, public health guidelines have operated under a metabolic assumption: 1 minute of vigorous-intensity activity (VIA) is equivalent to 2 minutes of moderate-intensity activity (MIA). This 1:2 ratio, based on estimated energy expenditure or METs (Metabolic Equivalents), focused on calorie burn rather than…

Metformin and Exercise Interference

By PJ Glassey / / Comments Off on Metformin and Exercise Interference

Some biohackers and longevity seekers are using the diabetes drug Metformin off-label as a “hack” for better health and longevity, but the research indicates that might not be such a good idea. Studies suggest that metformin may blunt key physiological benefits derived from exercise, raising caution for its use in healthy, physically active individuals. Metformin,…
