Balancing Intensity: The Science Behind the 80-20 Training Principle

In this episode of the Athletes Compass podcast, hosts Paul Warloski, Marjaana Rakai, and Dr. Paul Laursen dive into the 80-20 training model, a popular method for organizing training time among endurance athletes. They explore the origins of the model, its application in preseason training, and how it can be adapted for different training volumes. The discussion includes insights on the benefits of low-intensity training, the importance of monitoring heart rate, and the role of high-intensity sessions in a balanced training plan.

• The 80-20 training model suggests that 80% of training should be at low intensity (zones 1 and 2) and 20% at high intensity (zones 4 and 5).
• Originated by Dr. Steven Seiler, the model is based on observations of elite Norwegian cross-country skiers and their training methods.
• For athletes with limited training time (8-10 hours per week), the 80-20 model can still be effective, but other training plans may also yield results.
• Incorporating a small amount of high-intensity training during the base phase can lead to better performance in subsequent build phases.
• Monitoring heart rate is crucial for ensuring training is conducted at the correct intensity, especially for zone 2 workouts.
• The 80-20 model is flexible and should be adapted based on individual needs, training volume, and specific race goals.
