EP 170: Karly Rager & Casey Elliott — What the Data Says About Weight, Height, and Ape Index, and Which Metrics Matter for Climbing Performance

Karly Rager is back on the podcast and is joined by Casey Elliott to talk about the factors that affect climbing performance. We’ve got three engineers in one podcast, and we geek out on the data! Do things like weight, height, and ape index affect how hard you can climb? Is max finger strength more important than days spent climbing outside? Listen to find out!
