Building Capacity vs Utilizing Capacity
Phil and Jason discuss the difference between training that builds capacity for more training or better racing, and training that better utilizes current capacity. They explore the concept of building a bigger base through zone two and lactate threshold work, while also improving mitochondrial function through Vo2 max work. Phil shares insights on the time course of adaptation for mitochondria and the importance of both function and structure changes in response to training stress.In this clip
