In this solo episode, Spencer breaks down the full Ruck Deep Dive research series from Mountain Tactical Institute (MTI). He covers what actually predicts ruck performance, whether strength or endurance training matters more, and how to structure your training if you want to get faster under a ruck.

If you’ve been putting in miles but not seeing progress, this episode will make you reconsider how you train.

Corrections:

This episode credits MTI for conducting the study researching how fatigue changes how ruckers move under weight. This was incorrect. The study referenced was conducted by a team of researchers from the Department of Civil and Mechanical Engineering at the U.S. Military Academy West Point. Here is a link to that study.
