Fitness Consistency Score — How Consistent Are You Really?

The single biggest predictor of long-term fitness success isn't program design, supplement usage, or gym equipment — it's consistency. A mediocre program followed consistently for a year beats a perfect program followed sporadically. Yet most people track what they do on their best weeks, not what they actually average over time. The Fitness Consistency Score measures your true adherence rate by comparing planned sessions to completed sessions across multiple months. It surfaces patterns that are invisible in single-week snapshots: are your numbers declining over time? Do certain months consistently fall off? Is your plan unrealistically ambitious for your actual life? The scoring model rewards both high adherence rates and consistency of adherence — a person who completes 80% every month outscores someone who does 100% for three months then 40% the next. This reflects the biological reality: adaptation from training compounds over consistent exposure, not from heroic bursts interrupted by inactivity. Use this calculator to audit the last 3–12 months of training, identify your consistency patterns, and build a realistic plan going forward. The most important fitness decision you can make is choosing a schedule you will actually do.
