what-happens-if-i-do-not-know-my-threshold-and-fitness-values
If you don’t know your fitness value numbers, Athletica will make an estimate of this through your answers to a series of questions concerning your training and fitness history. If you don’t know your threshold values, Athletica will determine these for you using prescribed tests occurring in your training at appropriate points in your plan. Threshold values include your functional threshold power (FTP) for cycling, functional threshold speed (FTS) for running and critical swim speed (CSS) for swimming. As you continue on the program, Athletica uses a modified version of Banister’s training impulse (TRIMP) formula to understand further your level of fitness, fatigue and freshness.
