257. How To Build Muscle, Stay Lean, And Increase Your Health Span After 40

Most men over 40 think that slowing down, losing muscle, and gaining fat is just what aging does to them. But I am 52 with a biological age of 20, and I am here to tell you that age is not your problem. The excuses, the poor sleep, the sloppy programming, and the blind faith in stimulants and shortcuts are. In this episode of the Kris Gethin Podcast, I break down the exact training, nutrition, sleep, supplementation, and recovery principles that have allowed me to outperform most men half my age. Walk away from this episode finally understanding what is actually keeping you stuck, what to fix first, and what it genuinely takes to build muscle, stay lean, and perform at your best after 40. What's Discussed: (3:26) The real reasons men fall off after 40 and none of them are biological. (4:45) Four focused sessions versus six sloppy ones and which one actually builds muscle.
