Dumbbell Lateral Flexion

The Dumbbell Lateral Flexion / Extension, also known as Side Bends, works your abs as you move from side to side. The great thing about the dumbbell lateral flexion exercise is that you get to work your abs without doing a crunch! This exercise especially targets the obliques and lower abs.

By bending at your hip joints, resulting in a a decreased angle from your spine to pelvis, you are creating a “flexion” exercise. Your obliques are associated with your hips and waist, so that area will get some work as well.
