OVERVIEW
There's a misconception that mixing higher-intensity intervals and Zone 2 aerobic endurance riding in the same session is bad. The contention is that exposure to higher intensities hinders the stimulus that leads to improved fat oxidation. Coach Adam Pulford dispels this myth and explains how training zones work together and can be used in additive and complementary ways.

TOPICS COVERED

• How training intensities complement each other rather than cancel each other
• Aspects of fitness that can be improved at ALL INTENSITIES
• The limitation of focusing too much on improving fat oxidation
• How progressive overload works to gradually build fitness
