How FitWise Works
Apply the 80/20 rule to your fitness journey with AI-powered insights
🎯 Understanding Leverage in Fitness
The Pareto Principle reveals that results are rarely distributed evenly across your efforts. Historically described as "80/20" (20% of inputs create 80% of outputs), the actual leverage ratios vary by situation:
- Sometimes 15% of actions produce 85% of results
- Sometimes just 5% of actions produce 70% of results
- Sometimes 30% of actions produce 90% of results
What matters isn't hitting exactly 80/20 - it's identifying YOUR highest-leverage actions.
Recursive Leverage:
The principle compounds. If 20% of actions give 80% of results, then:
- 20% of that 20% = 4% of total actions
- Produces 80% of that 80% = 64% of total results
This is why we rank all 10 actions by leverage. Our top 3 recommendations typically provide 80%+ of your potential results, with the remaining 7 providing additional gains.
