Residual Training Stress™

Residual Training Stress™ (RTS™) is a FitLogic™ component technology that quantifies the lingering physiological impact of your training—the stress that remains in your body after workouts are complete. Unlike traditional metrics that only measure what happens during a session, RTS reveals the hidden recovery timeline that determines when you're ready to train hard again.
