One of the theorized benefits of low carb or ketogenic diets for cyclists is that it spares glycogen so it can be used when needed most. Kolie and Kyle walk through a paper investigating this question. They then discuss the upsides and downsides and potential utility of fat-adaptive diets in daily training.

​Does going slow make you slow? Do you need to go slow to make you fast? We look into the reasoning behind two opposite training philosophies, then figure out what aerobic base really is, what's effective, and why.

This episode begins with the mind-muscle connection of neural drive before diving into research on doing strength and endurance training concurrently, and how they interfere with each other. We then look at how the latest scientific research provides training solutions.

What do high intensity intervals, the original Tabata protocol, and a calcium leak have in common? Kolie and Kyle take a look at three scientific papers, what they might mean for you, and how to apply the conclusions to your training.

​Kolie and Kyle look at how duration and intensity play a role in FTP training. The discussion touches on how to structure workouts beyond 2x20, workouts for the time crunched and those with abundant time, and how to adjust workouts to account for TTE.

Bad news, everyone. You're training too hard for crits. Kolie and Kyle uncover the physiology of what makes someone successful at criteriums, cyclocross, and other types of repeated sprint performances. It's probably not what you think.

Kolie and Kyle take a deep dive into the pros and cons of the many FTP tests. "What is special about 60 minutes to the human body?"
What tests should certain people avoid? How hard is it to ride at your FTP? 20 and 60 minutes, 8 minutes, ramp test, and variable-duration FTP tests as discussed here: www.trainingpeaks.com/blog/the-physi…ing-protocols/
