The InnerFight Way

In endurance training, Training Stress Score (TSS) is a key metric. It measures how much load you’ve accumulated from a workout, factoring in intensity and duration. TSS helps us understand fatigue, plan recovery, and ensure progression. It’s vital for smart, structured training.

‍

But training isn’t lived in isolation. Enter Life Stress Score — the invisible number that’s harder to track but always present. It includes poor sleep, work pressure, family commitments, financial worries, emotional challenges, and more. Unlike TSS, there’s no watch or app to measure Life Stress, but it impacts our performance profoundly.

‍

If Life Stress is high, your body’s capacity to handle training decreases. Push through blindly, and you risk illness, injury, or burnout. This is where self-awareness, honesty, and adaptability become crucial.

‍

Your true performance metric will always be your Life Stress Score.
