Muscle
From NsdWiki
This attribute represents the character’s raw strength and power. This affects how much damage is inflicted in combat, and generally helps with tasks of brute force, such as pulling one’s self up from a ledge, holding a door shut against intruders, lifting a 10 ton boulder above one’s head, or crushing your opponents’ skulls like little tin cans.
Some examples of muscular people include Olympic weightlifters, furniture movers, and the Incredible Hulk.
