The Greatest Listener Email Ever

This week's episode was such a fun romp! The main training topic involved the often-overlooked variable of hemoglobin mass, and how optimizing hemoglobin levels for your individual genetics could help you bring out your inner aerobic monster. Important considerations: training intensity/stress, nutrition, iron intake, and oxygen stress like altitude... plus some wild new science on how year-round heat exposure may help. We also had a follow-up based on listener questions about how we like athletes to use heart rate data from their watches. Simple calculations to figure out your Zone 2 can help make running more productive and MORE FUN! Other topics: bands-core-massage replacing gym-tan-laundry, an update on Leo's health journey, setting little goals and how athletics can help, our framework for evaluating running shoes, ways to think about adding cross training, and the etiquette of going to the bathroom during races. 

We also read the most touching and soul-affirming listener message. We love you all so much!

This episode was our second hottest date of the week, after our 15-minute trip to the running shoe store. There is nothing sexier than trying on some new supershoes!
