Is it OK to workout on an empty stomach?

[martinahandy]

If you exercisein the morning, get up early enough to finish breakfast at least one hour before your workout. ... Studies suggest eating or drinking carbohydrates before exercise can improve workout performance and may allow you to work out for a longer duration or higher intensity.
