Quantifying Training Volume and Training Stress Score Relationship

The chapter delves into the relationship between Training Stress Score (TSS) and Functional Threshold Power (FTP) in training programs, discussing how changes in FTP affect TSS and the drawbacks of using TSS to equate different training intensities. The conversation explores different ways of quantifying sub-LT1 training load, comparing the use of kilojoules versus TSS versus hours, and emphasizes the importance of considering fatigue in training metrics.
