Most men are being told the same thing after 50:
"Low energy is normal."
"Losing muscle is normal."
"Low testosterone is just part of aging."
Dr. John Jaquish says that's nonsense.
In this episode of the Fit Over 50 Life Podcast, Mark Patrick and Kelli Calabrese sit down with Dr. John Jaquish — biomedical engineer, inventor of OsteoStrong and X3, bestselling author of Weight Lifting Is a Waste of Time, and one of the most controversial voices in fitness and longevity.
This conversation goes deep into testosterone, strength, aging, muscle loss, hormones, metabolic health, recovery, resistance training, and why so many men today feel weak, tired, overweight, and burned out.
Dr. Jaquish explains what's really happening to testosterone levels in modern society, why traditional TRT may be flawed, and how strength, muscle, protein, recovery, and hormone optimization impact longevity and quality of life after 50.
