Need a quick ab burn? This routine is great for when you are in a hurry or just want to get in an extra workout. When performing the moves, focus on maintaining proper form (especially keeping your lower back on the floor when on your back), and remember to breath. Inhale when you go back and exhale when you crunch or reach up.
