176. Hemoglobin and VO2 Max, Zone 1 Training, Your Watch's Metrics, and Prototype Shoes!

We ate a truly stunning amount of chicken and milkshakes to fuel this great episode! The main training topic was on a new review article connecting hemoglobin levels and VO2 max. Across nearly 400 studies, these variables have a strong statistical correlation. Blood volume could be primary a driver of performance, and we break down some simple ways to optimize your levels.

We also celebrated Megan's return to training after some good health news! That was a great excuse to talk about the lost art of Zone 1 training. Easy can be very, very easy (at least some of the time). Your mitochondria and muscle fibers will thank you!

And this episode featured a ton of our favorite discussion points! Other topics: energy availability and our jaw-dropping Chick-Fil-A order, developing the entire aerobic curve, 3 ways to support self-belief, an incredible story from baseball's Philadelphia Phillies, doping thoughts, our issues with prototype shoes, qualities of good coaches (and whether they need to run themselves), your watch's metrics, whether you should pay attention to them, and hot takes. One of our listeners has a disturbing view of toilet paper that you need to hear... and ignore.
