A new study challenges the hype around Zone 2 training, but Trevor and Chris explain why the real answer is more nuanced: intensity matters, Zone 2 still has value, and coaches and researchers need to work together to understand both.
We discuss new research on what it takes to win the biggest races in cycling—and how that can help your own racing—and we analyze a study that looks at the potential causes of overtraining syndrome.
Based on their recent research article, the Seilers discuss the proliferation of training zone systems and compare them to the highly touted Norwegian five-zone model.
Zone 2 training has become all the rage, but a 2025 review is taking a step back and questioning whether it really produces the gains we thought it does.
Recently, some prominent researchers have suggested that women need far less zone 2 training than previously thought. Physiologists Julie Young and Dr. Dana Lis join us to debate that question.
If you have a lot of races lined up this season, don’t forget to make time for some sweet spot work to maintain your high-end aerobic fitness.
Your lactate threshold may not be what you think it is. Coach Trevor Connor explores the true definition of this physiological turn point.
Training zones have served an important role for decades, but with the sophistication of training software and portable devices, do they still have a place?
Coach Alec Donahue of Cycle-Smart helps us answer questions about training zones, cyclocross, weekly planning, and alcohol.
Pro mountain biker and coach Hannah Finchamp helps us field questions on time-crunched training, zone 1, interval design, and more.
Dr. Stephen Seiler explains the endurance training zones schemes he uses in research (3 zones) and in practice working with Norwegian coaches and athletes (5 zones) as part of the Norwegian Olympic Federation model.
How accurate are threshold numbers? And why is it so difficult to find accurate threshold numbers? We discuss several common ways to find your threshold and their pros and cons.
In this episode we look at the big picture when it comes to training in zones, or ranges, versus training a target number. Because what number is best?
We talk with exercise physiologist Jared Berg about the value of athlete physiology testing like VO2max and lactate testing at the University of Colorado Sports Medicine and Performance Center.
Training zones can have tremendous value when they guide workouts and help us talk about how we train. But training zones can be problematic.
Trevor and Chris field listener questions on importance of aerobic threshold, FTP, muscle soreness, and training in extreme cold.
We take on a controversial subject: FTP or functional threshold power. Is FTP dead?
