よくある質問

What is ape index in boxing?
Ape index (or ape factor) is reach minus height. A positive value means your arms are longer than your height, giving a natural reach advantage. Negative means shorter arms relative to height.
How important is reach in boxing?
Reach advantage allows a fighter to hit without being hit, control distance, and land jabs while staying outside the opponent's range. It is most beneficial in stand-up technical boxing.
Can a shorter fighter overcome a reach disadvantage?
Yes. Shorter fighters often compensate by cutting the angle, slipping punches, and working inside the opponent's reach, where their longer-armed opponent loses the advantage.
