Overview
The 'Ape Index' is the ratio of your arm span (wingspan) relative to your height. A ratio greater than 1.0 means your reach is longer than you are tall, which is typically advantageous in sports.

Pro Tips
In rock climbing, a high Ape Index allows you to reach distant holds that others might struggle with.
In boxing and MMA, a longer reach allows you to strike from a distance where your opponent cannot hit back.
Swimmers with high ratios like Michael Phelps (1.04) benefit from more powerful strokes.
