Why should you bother lifting heavy? Is resistance training really safe? And what’s the deal with cardio supposedly “killing gains”? In this episode, I sat down with the strongest person I know (literally)—strength coach, certified athletic trainer, and competitive powerlifter, John Flagg—to tackle these questions and more.

We break down:

  • The key differences between weightlifting vs. powerlifting vs. resistance training
  • Why resistance training is crucial for overall health and longevity
  • The biggest myths about lifting heavy and injury risk
  • The shift in women’s strength training culture and how more women are embracing lifting
  • Why John and his wife introduced their daughters to lifting at a young age
  • The truth about cardio and strength training—does it actually hurt your gains?

Whether you're a seasoned lifter or new to strength training, this episode will provide valuable insights into the benefits of lifting heavy for your health and longevity.
