Training Stress Score

Training Stress Score (TSS) is a metric that quantifies the overall training load and stress an athlete experiences during a workout. It considers factors like intensity, duration, and effort to provide a single number that reflects how demanding a session was. Higher TSS indicates a more taxing workout, helping athletes and coaches plan training to balance effort, avoid overtraining, and optimize recovery. Essentially, TSS turns the complex physiological impact of exercise into an easy-to-understand score, aiding in tracking progress and managing training intensity over time.
