Side Bend
Description
The dumbbell side bend is an oblique isolation exercise where you stand with a dumbbell in one hand and lean to that side, then return to upright by contracting the opposite obliques. It builds the lateral core musculature. Use moderate weight — heavy loading can thicken the waist over time.
Equipment Required
Side Bend Instructions
- Stand tall with feet shoulder-width apart. Hold a dumbbell in your right hand at your side.
- Place your left hand behind your head or on your hip.
- Brace your core and keep your hips stable.
- Lean directly to the right by bending laterally at the waist. Lower the dumbbell down your right thigh.
- Continue until you feel a stretch in your left obliques.
- Return to upright by contracting your left obliques. Squeeze hard at the top.
- Complete all reps on one side, then switch.
- Use moderate weight (15 to 30 lbs) for 12 to 15 reps. Avoid very heavy loading.
