Track cumulative training stress, not just individual sessions

A single hard session is not the risk — it is the week-over-week accumulation of stress without matching recovery.

Why it works

Supercompensation occurs at the session level, but overreaching and overtraining occur at the block level: it is the cumulative ratio of stress to recovery over weeks that determines whether the athlete is adapting or eroding. Metrics like Acute:Chronic Workload Ratio (ACWR) try to capture this: when acute load (recent week) significantly exceeds chronic load (rolling average), injury and overreaching risk rise.

How to do it

1. Track weekly training load using a consistent metric (total session time, training impulse, or total sets per muscle group).
2. Calculate a 4-week rolling average; keep any single week within 10–15% above the rolling average.
3. Spike weeks (competitions, travel disruption) require the following week to be lighter than usual.
4. Log not just training stress but also life stress — they accumulate in the same recovery budget.

Evidence

ACWR as an injury risk predictor has evidence in team sports (football, cricket, rugby) and is a widely used athlete monitoring tool, though its predictive accuracy is debated in recent literature. (observational)

Revised analyses question ACWR’s predictive accuracy for injury specifically, while affirming the broader principle that rapid load increases are a risk factor.

Common mistake

Measuring training stress only in the gym and ignoring the load from sleep deprivation, travel, work deadlines, and emotional stress — all of which compete for the same recovery resources.
