Winged Scapula

Winged scapula is a common biomechanical deficiency which is caused by two things: short (tight) pectoralis minor and long (weak) serratus anterior/lower trapezius. In severe cases, it looks like a person's shoulder blades are poking up out his or her back. I saw one guy on the bike course at Lawrence 70.3 who made me cringe, his scapulae were so poky. But in a less severe case, the condition will show itself if you push hard against a wall with palms flat at waist level (not sure on the biomechanics of why this is the case, beyond the fact that this movement should use the serratus anterior and if they're weak it'll show up here). One of the other trainers at my gym did this once and completely grossed me out. He looked like a frickin' gargoyle.
