 34. Minimum effective dose (choosing the right training stimulus) | File Type: audio/x-m4a | Duration: 00:09:06

Luke clears up the training philosophies used at METS, what minimum effective dose means, and how it can be used to train smarter, not harder.

 33. Fatigue is Multifactorial | File Type: audio/x-m4a | Duration: 00:19:19

Luke discusses the different types of muscle fatigue an individual can experience during an event and how to best combat it. More free resources at

 32. How hard is too hard? | File Type: audio/x-m4a | Duration: 00:10:16

In this episode, Luke discusses two questions: 1. Should threshold and VO2 max workouts be separated? 2. When is the right time to increase the pace of your intervals? METS is trialing a pricing restructure in February. New clients can book a VO2 max test for $99 (down from $185) by using the coupon code 99TEST when booking online here: For more info, sign up to our free content at
