The oblique raise off bench is a side-lying trunk raise performed with the hips on the end of a bench and the feet anchored, lifting the torso sideways against gravity to train the obliques. Because the upper body hangs unsupported past the bench, the obliques work through a full range of lateral flexion, from a stretch below the bench line to a squeeze above it, which a standing side bend cannot load. The bottom oblique does the lifting while the top one steadies the ribs. Lifters use it as a late core accessory on a leg or pull day.
What Muscles Does the Oblique Raise Off Bench Work?
- Primary: External oblique, internal oblique (bottom side)
- Secondary: Quadratus lumborum, erector spinae, rectus abdominis
- Tertiary: Gluteus medius (anchoring leg), hip adductors, latissimus dorsi
How Do You Set Up for the Oblique Raise Off Bench?
Use a flatbenchor a hyperextension bench with the ankles hooked under the pads. Lie on one side with the hip bone at the end of the pad and the torso hanging free. Stack the legs, top foot in front, and have a partner hold the ankles if there are no pads. Cross the arms over the chest. Let the torso hang in a straight line with the legs.
How Do You Perform the Oblique Raise Off Bench?
- Set the hips on the pad edge, legs anchored, torso hanging straight and shoulders stacked.
- Raise the torso sideways by pulling the bottom ribs toward the top hip, keeping the shoulders stacked and the head in line.
- Stop when the torso rises above the line of the legs and the bottom side of the waist is fully shortened.
- Hold the top for one count, squeezing the waist without twisting the chest toward the ceiling.
- Lower the torso slowly past the bench line until the bottom side of the waist stretches.
- Pause at the bottom, keep the shoulders stacked and lift again; switch sides after the set.
What Are the Key Form Cues?
- Ribs to hip: shorten the space between the bottom ribs and the top of the pelvis rather than lifting the shoulder toward the ceiling.
- Stay in one plane: imagine the body sliding between two panes of glass so the chest never turns up or down.
- Keep the neck long and the ears in line with the shoulders through the whole rep.
- Feel the stretch along the bottom side of the waist at the bottom before starting the next lift.
- Press the top foot into the bottom one so the legs stay locked together.
What Are the Most Common Mistakes?
- Rolling the chest toward the ceiling on the way up: the rep becomes a twist and the rectus abdominis takes over from the obliques; keep the shoulders stacked and lift purely sideways.
- Swinging the torso up: momentum carries the lift and the obliques only work at the top; raise on a two-count from a dead stop at the bottom.
- Pulling on the head with the hands: the neck flexes sideways and the shoulders round; hold the hands lightly or cross the arms.
- Setting the hips too far onto the bench: the pad blocks the range and the torso cannot drop below the bench line; put only the hip bone on the edge.
- Hiking the top hip toward the ribs: the legs bend at the waist and share the work; keep the hips still and let the ribs do the moving.
What Are the Best Oblique Raise Off Bench Variations?
- Side plank hip drop: a floor version with a smaller range, for lifters not yet strong enough to lift the hanging torso.
- Weighted oblique raise off bench: a plate held at the chest for more load.
- Side bends at hyperextension: the same movement with the thighs supported on the pad.
- Oblique raise with a reach: the top arm reaches overhead at the top for a longer lever.
- Stability ball side crunch: the same arc with the hip on a ball and the feet against a wall.
How Do You Progress the Oblique Raise Off Bench?
- Add a 5 to 10 pound plate at the chest once you complete every set at the top of the rep range without twisting.
- Build from 10 reps a side to 15 before adding the plate.
- Add a fourth set per side when three no longer fatigue the waist.
- Add a two-second hold at the top, or lower on a three-count into the stretch.
How Should You Program the Oblique Raise Off Bench?
Place the oblique raise off bench at the end of a leg or pull session, after squats or deadlifts have finished, two or three times a week. Work 3 to 4 sets of 10 to 15 reps a side with 45 to 60 seconds of rest between sides. Pair it with a hanging leg raise or a cable crunch so the trunk is trained in two planes.
