How does swimming burn so many calories (close to higher intensity workouts) even if my heart stays in the warm up zone the whole time?

I suck at swimming and I’m not a high level athlete but even 2 or 3 laps gets my heart rate up real quick. There are not too many exercises that engage that many muscle groups at once.
If your heart rate is not going up you’re either not really swimming at any reasonable speed or you are elite level athlete.
