Dumbbell Side Bend

Muscles Dumbbell Side Bend Works

Muscles used

• Obliquesside abs running from the ribs toward the pelvis
• Quadratus lumborumDeep muscles below the ribs
• Transverse abdominisThe deepest core muscle that wraps around your abs
• Erector spinaeThe vertical muscles along your spine from neck to lower back

Main muscleHold a dumbbell and bend your torso to the side. The main muscles used are your obliques, which pull your ribs and pelvis together to create the side-bending motion.

Supporting musclesThe quadratus lumborum helps with side bending, the transverse abdominis keeps your core stable, and the erector spinae supports your spine.

How it should feelAs you rotate, one side of your waist should shorten and squeeze. Move with control so you feel your ribs moving toward the opposite hip.

Signs you're offIf your body leans forward or backward or your lower back bends, you’re moving with your lower back instead of your obliques. If you swing the dumbbell for momentum, you’ll reduce the activation of your obliques.

Remember thisKeep your torso steady and slowly bend to the side.
