After waking up from his coma, Barry Allen notices a very nice benefit of being struck by lightning:
"Lightning... gave me abs?"
In the teaser trailer, Oliver's shooting in the woods when Barry does an Arrow Catch, to which Oliver snarks "Show off." Not 30 seconds later, the ad shows Oliver priming three arrows, and Barry smirking.
When they're testing Barry's speed, they put him in a red outfit that looks like it was designed to minimize wind resistance while still providing padding for falls, with a helmet to boot. The result looks completely ridiculous.
