spring into action
Leap to work
To spring into action is to shift suddenly from inactivity to energetic effort, often in response to a crisis or urgent need.
The phrase emphasizes the abruptness of the transition—one moment idle, the next fully engaged: When the alarm sounded, the firefighters sprang into action.
It suggests readiness and decisive movement.
