Marginal gains (En)

“The concept of 1% improvement, often called “the 1% rule” or “marginal gains”, is the idea that making tiny, consistent improvements — about 1% better each day — can lead to significant long-term progress because of compound growth.

Here’s how it works:

The Core Idea

Instead of trying to make big, dramatic changes all at once, focus on small, manageable improvements in your habits, processes, or skills. Over time, these small improvements accumulate and multiply.

Mathematically:

• If you get 1% better every day for a year:
  1.01365≈37.781.01^{365} \approx 37.781.01365≈37.78 → You’ll be 37 times better after one year.
• If you get 1% worse every day for a year:
  0.99365≈0.030.99^{365} \approx 0.030.99365≈0.03 → You’ll almost lose all your progress.

Example in Practice

Personal growth: Reading 1 page a day becomes 30 books in a year.

Fitness: Adding 1% more effort to your workouts improves strength and endurance steadily.

Business: Improving small processes (like response time, product quality, or communication) adds up to big competitive advantages.

The idea was popularized by Sir Dave Brailsford, coach of the British Cycling team, who applied the philosophy of “aggregation of marginal gains” — improving every small aspect (sleep, diet, bike design, etc.) by 1%. The team went from mediocrity to dominating world cycling within a decade.
