You actually believe that the average woman can pull a 100 pound bow?!?!

You don't know that Youtube user. Lindybeige specializes in medieval and ancieht weapons, so he made this video to make a point about tv/movie portrayals of bows.

Lindybeig actually studies medieval weapons, so yeah he knows what he's talking about.

I believe the Mongols used composite bows that also had huge pull strengths.
