Physical strength

The magnitude of physical strength, often referred to as just strength, determines the ability of a person or animal to exert force on physical objects using muscles.

Strength can be divided into two categories:

; short-term endurance : allows use of great physical force for small period of time (few seconds) ; long-term endurance : allows use of adequate physical force extended periods of time like several hours

Many studies show that training the other rigorously harms the other - eg. large muscles are good for maximal power during short time periods, but they consume lots of oxygen which muscles need a lot during long periods of exercice.

Many athletes depend on mostly on physical strength, even though coordination and dexterity also play an important role.
