If you want more mighty-thewed barbarians superior to those weakened by the decadence of civilization, these are the feats you have been looking for.
1 with a Bullet Point: 8 Barbarian Feats is a 3-page PDF (2 pages if you remove the credits/OGL page) for the Pathfinder RPG written by Owen K. C. Stephens and published by Super Genius Games. This is part of Super Genius Games’ #1 with a Bullet Point (One Idea, One Page, One Dollar) line.
The layout is a screen-friendly landscape design, with cover art and 1-column on the first page and three columns on the rest. There are a couple black and white pieces of art appropriate to the subject.
This entire product range is designed around presenting a single idea quickly and efficiently, as explained on the first page, then it moves onto the framing idea for the product (simulating certain iconic fiction barbarians) and the eight feats to do so. This will allow you to build the Iconic Barbarian with Mighty Thews and Panther-like Grace.
Disclosure: As a featured reviewer for RPGNow/DriveThruRPG, I received my copy of this product for free from the publisher for the purpose of this review.
