Acute:Chronic Workload Ratio (ACWR) & Sports Injury Prevention Calculator (Tim Gabbett Model)
Calculate your Acute:Chronic Workload Ratio (ACWR) comparing your current week's training load (acute fatigue) to your rolling 4-week average (chronic fitness) to stay in the injury-free 'Sweet Spot' (0.8–1.3) and avoid the Danger Zone (> 1.5).

Calculation Methodology
ACWR = Acute Workload (Current 7-Day Load) / Chronic Workload (4-Week Rolling Average Weekly Load). Sweet Spot = 0.8 - 1.3. Danger Zone = > 1.5.
