The Barbell Side Bent (version 2) is a standing waist exercise that primarily targets the obliques, with the iliopsoas assisting to stabilize the trunk. With a barbell resting across your upper back and shoulders, you bend sideways at the waist to load the muscles on the side of your torso. It is a simple way to build oblique strength and lateral-flexion control.
How to do the Barbell Side Bent (version 2)
- 1Position a barbell across your upper back and shoulders as you would for a back squat, gripping it with both hands to keep it stable.
- 2Stand tall with your feet about shoulder-width apart, knees slightly soft and your core braced.
- 3Keep your hips and shoulders square to the front, facing straight ahead throughout the movement.
- 4Bend slowly and directly to one side at the waist, lowering your torso toward that hip until you feel a stretch along the opposite side.
- 5Keep the bend purely lateral — do not lean forward or backward and do not twist your torso.
- 6Contract the obliques on the opposite side to pull yourself back up to a tall, upright standing position.
- 7Complete your reps to one side, then repeat for the same number of reps on the other side.
- 8Re-rack the barbell safely once both sides are finished.
Form tips
- Move under control in both directions — lower slowly and avoid using momentum to swing the weight.
- Keep your hips relatively still so the motion comes from bending at the waist, not from shifting your pelvis side to side.
- Brace your abs throughout the set to protect your lower back and keep tension on the obliques.
- Start light to groove the lateral-flexion pattern; this is a small range-of-motion movement that does not need heavy loading.
- Use a rack to set up and re-rack the bar, and stop the set if you feel any pinching in your lower back.
Common mistakes
- Bending forward or backward instead of straight to the side, which shifts the work off the obliques and loads the lower back.
- Twisting or rotating the torso during the bend, which turns the lift into a rotation movement and reduces oblique tension.
- Using too much weight and jerking the bar, which relies on momentum rather than the obliques and risks straining the back.
- Pushing the hips out to the opposite side to lean further, which removes tension from the waist and cheats the rep.
- Working only one side or using uneven reps, which builds a strength imbalance between the two sides of your waist.
Frequently asked questions
What muscles does the Barbell Side Bent (version 2) work?
It primarily works the obliques, the muscles along the sides of your waist, with the iliopsoas assisting to stabilize the trunk during the lateral bend.
How wide should my stance be?
About shoulder-width apart gives a stable base. Keep your feet planted and your knees slightly soft so the bend comes from your waist rather than your legs.
Is the Barbell Side Bent (version 2) good for beginners?
Yes, as long as you start light and focus on bending purely to the side. The pattern is simple, but the lower back is vulnerable, so build the movement before adding load.
How many sets and reps should I do?
Treat it as accessory work: roughly 3 sets of 10 to 15 reps per side with a light to moderate weight. Match the rep count on both sides to avoid imbalances.
Should I bend forward at all during the movement?
No. The bend should be straight to the side at the waist, with no forward or backward lean and no twisting, so the obliques do the work and the lower back stays protected.
