You are in excellent physical condition, enabling you to extend physical activities. You might not have great strength, but you have a lot of stamina.
This feat is a bonus feat for the Scout and Soldier classes.
Prerequisites: Strength 13, Constitution 13.
Benefit: You can reroll any Strength- or Constitution-based skill checks for skills that you are trained in. The result of the reroll must be accepted even if it is worse.
