Question #1: Lactic Acid

  • Hi, my name is Ryan, I’m a long time listener and huge fan of the show. I never thought I’d be one to email a correction but after listening to the most recent episode I noticed that you briefly touched on on each of the more pervasive fitness misconceptions. Lactic Acid was for a long time thought to be the source of soreness but most of the recent research seems to point to that not being the case. I won’t do justice to trying to explain it but it this might be a great chat about one of the most common fitness misconceptions. Anyway, keep up the great work, love the show. Ryan George New York
  • I have listened to your podcast for a year and really appreciate all that you do. I just listened to your most recent episode and I am confused on one thing: what’s the difference between climate change and global warming? Annika L Jorgensen (Anne- I- ka jor- gen- sin) Utah
