Your Fitness, Stress, & Readiness™ (FSR™) graph is an Optimized Training™ visualization of your current, past, and planned Residual Training Stress™ (RTS™), 7-Day RTS (RTS7™), Normalized Training Load™ (NTL™), and Performance Readiness™.
Your FSR graph does not describe your "performance ability" nor is it intended for you to use to manage your own training. Its purpose is to help you visualize and better understand the ongoing optimization of your training load, stress, and readiness to support and increase your performance ability.
Residual Training Stress™ (RTS™)
Residual Training Stress (RTS) quantifies the residual effect of past training sessions on your body based on various session characteristics such as intensity, duration, and frequency, among other factors. Learn more about your RTS.
Unlike Normalized Training Stress™ (NTS™) which is a session-specific stress metric, RTS is a point-in-time metric comprised of stress from as many as several dozen past training sessions. Learn more about your NTS.
