ELI5: In light of the article about the 19 year old female lifting the truck off of her dad to save his life, how is it physically possible for a human to do that even with the high amount of adrenaline that is present?

The human body is incredibly durable and much stronger than we normally assume, this is because when we're calmly exerting ourselves (like in the gym) we're aware of the stress the load puts on our body, and as such we are cautious to avoid injury.  With massive amounts of adrenaline that awareness fades to the background. It allows a person to use the upper limit of their capabilities, possibly damaging themselves in the process. Another factor is just how much was needed. Most people picture superman lifting the car over his head, when in reality even a fraction of an inch can give the needed escape room to survive.
