How to perform the Dumbbell Side Bend
- Stand tall with feet shoulder-width, a dumbbell in one hand hanging at your side and the other hand behind the head.
- This is loaded lateral flexion of the spine, so keep every rep slow and controlled rather than bouncing out of the bottom.
- Keeping the hips square and facing forward, bend sideways at the waist to lower the dumbbell down the side of the leg.
- Let the spine flex only in the frontal plane. Do not twist the torso or lean forward and back as you lower the weight.
- Descend to a comfortable stretch on the loaded side without rounding or rotating, feeling the opposite oblique lengthen.
- Contract the top-side obliques to pull the torso back upright, and load only one hand at a time to avoid canceling the resistance.
Suggested working range: 12–20 reps. Default progression: double progression.
Common mistakes
- •Bending fast and heavy through the loaded spine instead of moving slowly under control.
- •Twisting the torso or leaning forward and back instead of bending purely to the side.
- •Holding a dumbbell in each hand at once, which cancels the resistance and removes the training effect.
- •Letting the hips shift sideways to swing the weight up rather than contracting the obliques.
Variations & alternatives
