If this seems underpowered, increase the 1 to a 2 or a 3 or something, or make it a trait instead of a feat.
Brawn Over Brain[General]
Some people use their understanding to gain greater insight into how to perform better physically... others don't let having the attention span of a squirrel on a sugar rush stop them from having the acrobatic skills of one.
Intelligence 11 or lower (minimum 3)
Strength greater than Intelligence OR size Tiny or smaller
Constitution greater than Intelligence
Dexterity greater than Intelligence
Replace your intelligence modifier with a 1 when calculating the number of skill points you get each level.
You may not put skill points into or take feats that give bonuses to NORMALLY cross-class Intelligence, Wisdom, or Charisma based skills, and such skills that NORMALLY are class skills count as cross class (but never exclusive to another class). This means (for example) that a Rogue with this feat can still put skill points into Use Magic Device, but he only gets 1 skill rank per 2 skill points he puts into it and a can have a maximum number of ranks in the skill of (Character Level +3)/2.
For the above purposes, "Speak Language" is considered to be an Intelligence based skill. Which means, for example, that a fighter with this feat can't put skill-points into "Speak Language" and a bard with this feat would treat "Speak Language" as a cross-class skill. There are still no skill rolls involved and still no such thing as "partially fluent" in a language.
The number of skill points you get each level is affected by your intelligence modifier.
A fighter may take this as one of her bonus feats. A Monk may take this feat as her first level bonus feat instead of Improved Grapple or Stunning Fist.
EDIT May 2011: Added clause "OR size Tiny or smaller" to strength requirement line. Now it really DOES work for awakened squirrel monks.
Just so you can have a (probably NPC) Rogue or Monk or Barbarian with a 6 Intelligence who can still jump, swim, and climb very very well... what do you all think?
Edit: Here is a 2nd level 22 point Half-Orc Tumble -> Flank -> Sneak Attack specialist
built around this feat just for an example.
