Shownotes

Most people are chasing the wrong version of strength and paying for it with pain, poor movement, and a body that breaks down faster than it should. In this episode, Dr. Gabrielle Lyon sits down with Mark Bell, elite powerlifter, entrepreneur, and founder of Slingshot, to discuss:

  • Why strength training is essential at every age but most people are defining "strength" too narrowly
  • How modern life has created an "exercise deficiency," and why artificial exercise is the only fix
  • The truth about fat, protein, and the biggest nutrition mistakes holding people back from lasting weight loss
  • The emerging peptide and drug landscape, and what it means for the future of health optimization
  • Why forcing your kids to move isn't cruelty, it's one of the most protective things you can do as a parent

Whether you're 25 or 75, this episode will challenge how you think about movement, muscle, and what it actually means to be strong physically and mentally.
