Barbell Side Bent
- Intermediate
- Compound
- Rep-based
- Waist
The Barbell Side Bend targets the obliques through lateral spinal flexion, enhancing core stability and trunk strength. By placing the load across the shoulders, it creates a longer lever arm than dumbbells, significantly increasing the demand on the lateral stabilizers.

Setup
- Position a barbell across your upper trapezius muscles, using a grip slightly wider than shoulder-width.
- Stand with your feet hip-width apart and a slight bend in your knees to stabilize the lower body.
- Brace your core and pull your shoulder blades together to create a stable shelf for the bar.
How to do it
- Inhale and slowly bend your torso to one side, lowering the end of the bar toward the floor while keeping your pelvis completely stationary.
- Exhale as you contract the obliques on the opposite side to pull your torso back to a vertical, neutral position.
- Repeat the movement on the other side, alternating sides for each repetition in a controlled 2-0-2 tempo.
Form checklist
- Keep your hips locked in place; do not let them shift laterally to compensate for the weight.
- Move strictly in the frontal plane, ensuring you do not lean forward or round your lower back.
- Maintain a proud chest and keep your head in a neutral position throughout the movement.
- Ensure the movement originates from the waist rather than the hips or shoulders.
Pro tips
- Focus on the 'stretch' of the oblique on the side opposite the bend to maximize muscle fiber recruitment.
- Keep your glutes squeezed throughout the set to provide a stable base for the spine to move against.
- Imagine your body is between two panes of glass to ensure you stay in a perfectly straight lateral plane.
Make it harder
- Increase the time under tension by adding a 2-second isometric hold at the point of maximum lateral flexion.
- Narrow your stance slightly to decrease your base of support, forcing the core to work harder for balance.
Frequently asked
- What muscles does the barbell side bent work?
- The barbell side bent primarily targets the obliques, and also works the erector spinae as secondary muscles.
- What equipment do you need for the barbell side bent?
- The barbell side bent uses barbell and weight plate.
- Is the barbell side bent good for beginners?
- The barbell side bent is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
