As structure for a larger discussion on performance, adaptation, and energy needs, we tackle three myths about burning carbs and fats: that you only need to replace the carbs you burn on a ride, that burning fat on a ride helps you lose weight, and that total energy needs are as simple as converting bike kJ to calories and adding a calculated BMR. We also answer listener questions on efficiency, the origin of the 2000 calorie diet, where your workout carbs go, fueling for ultras, and more.

This episode covers practical cues that we use to be reasonably certain that workouts will have their desired effect, and tease apart the difference relationship between stimulus and adaptation. We give suggestions for the major training modalities including threshold and VO2max, plus strength and hypertrophy. We also discuss ways that these cues could be easily misused, plus the pros and cons of some other potential proxies like fatigue, power, heart rate, RPE, HRV, soreness, TSS, and more.

Our Empirical Cycling coaches have a roundtable discussion on the most under appreciated and impactful big-picture training habits you can make. We discuss progress expectations, goal setting, all or nothing mentality, vicious and virtuous cycles, balancing personal priorities, and many other factors that are within our control to improve. Then we tackle listener questions including improving climbing and low cadence training, high or low "zone 2", what to do about low motivation to ride, fueling early morning riding, and much more.

Finally tackling one of our most requested topics, we discuss the options available for cyclists doing strength training at home with limited or no equipment, and suggestions for cost effective equipment. We go through exercise selection, loading strategies, biomechanical considerations, sets reps and rest schemes, hypertrophy vs strength, sprint power transfer, isometrics, and more. The pros and cons and realities of our suggestions are weighed, a couple thoughts in relation to general health, and many listener questions are answered.

Kolie, Kyle, and Rory go deep into why "the science says" may not be what the science actually says. We discuss the difficulty of the task, the statistical and group-average nature of most results, the fallacy of division, what counts as evidence-based practice, motivations behind clickbait titles and more bullish stances, and where we'd like to see the field of exercise science go in the future.

Billy Ryan of Aware Performance joins to discuss performance psychology. He gives practical guidelines and skills for training and racing, while uncovering their underlying methodology. We cover negative thoughts and feelings around performance, being rigidly flexible, mental focus, confidence vs competence, shaken confidence, and much more. Then we go deep on listener questions.

This upload fixes the audio cutoff problem from the previous upload.

Dr. Traci Carson joints to discuss low energy availability and relative energy deficiency in sport, or LEA and RED-S. We consider their origin in the female athlete triad, some differences in female and male physiology and symptoms, the fuzziness of energy intake, symptom overlap with fat loss diets, the need for carbohydrates, the relationship to similar conditions like overtraining syndrome, social considerations and assessing cycling's broader awareness on these issues, and much more.

This episode plays out one of Kolie's coaching thought experiments: what's the simplest training plan possible that would probably be effective for the largest number of people? We each present our plan and then critique them, once again realizing how difficult it is to create a plan without our usual tool of athlete feedback. This starts a discussion about the best potential audience for each plan, the different needs of beginner, intermediate, and advanced athletes.

We discuss everything sweetspot. How do we define it, what kind of training is it, what's the nature of progression, how much is too much, upsides and downsides including time efficiency, fueling, over/unders, and more. We also answer tons of listener questions, like if it can raise FTP, if it's overrated or underrated, sweetspot for sprinters, how long you can hold it relative to your FTP, and much, much more.

A study knocking out HIF1alpha in mice reveals a counterintuitive relationship between markers of phenotype like fat oxidation, mitochondria markers, capillary density, and fiber type, and not having improved baseline performance. This uncovers an interesting relationship between the HIF pathway and oxidative metabolism, and how seemingly opposing adaptations are complementary.
