Static stretching is probably what you think of when you think of 'stretching', holding a pose for 10-30 seconds. Dynamic stretching is when you move around. Lunges, jumping, calf raises are all examples of dynamic stretching. A quick google for 'runner dynamic stretches' would be informative. The important part is that static stretching before workouts has been linked to increased risk of injury, and lower performance. Stretching post workout and on non-workout days is fine.
