The plank hip twist is a bodyweight core exercise performed in a forearm plank, rotating the hips to dip each side toward the floor while the shoulders stay square over the elbows. Unlike a static plank, which only resists sagging, it loads theobliquesthrough their rotational range against a fixed upper body. Where a Russian twist rotates the ribcage over still hips, this movement rotates the pelvis under a still ribcage, so the lower fibres of the obliques do most of the work. Lifters use it as a core accessory late in a session.
What Muscles Does the Plank Hip Twist Work?
- Primary: External and internal obliques
- Secondary: Rectus abdominis, transverse abdominis
- Tertiary: Serratus anterior, anterior deltoids (front shoulders), gluteus medius (side glute)
How Do You Set Up for the Plank Hip Twist?
Lie face down on a mat and set your elbows directly under your shoulders, forearms parallel or hands clasped. Extend your legs behind you with your feet together and the balls of your feet on the floor. Lift your hips until your body forms one straight line from head to heels, tuck your chin so your neck is neutral, brace your abs, and squeeze your glutes before the first twist.
How Do You Perform the Plank Hip Twist?
- Set your plank with hips level with your shoulders, elbows under shoulders, and feet together.
- Rotate your pelvis to the right, dipping the right hip toward the floor while your elbows and shoulders stay planted and square.
- Stop a fist's width above the floor or where the left oblique feels fully stretched; the shoulders have not moved.
- Pause for a beat at the bottom, then pull the hip back up using the left oblique rather than swinging.
- Rotate through center to the left, dipping the left hip the same distance under the same control.
- Return to the level plank and check the hips are back in line before the next pair of twists.
What Are the Key Form Cues?
- Hips move, shoulders do not: picture a headlight on your chest pointing at the floor for the entire set while the pelvis rotates beneath it.
- Twist from the waist, not the feet: the feet pivot on the toes, but the rotation starts at the belt line.
- Keep the hips at plank height as they turn; dropping lower means the plank is collapsing, not rotating.
- Squeeze the oblique on the top side to pull the hip back through center.
- Exhale at the bottom of each dip so the ribs stay down and the brace holds.
What Are the Most Common Mistakes?
- Sagging the hips toward the floor between twists: the lower back takes the load instead of the abs, and each twist starts from a broken plank; reset to a straight line every rep.
- Turning the shoulders with the hips: the whole body rolls as one unit and the obliques never work against the anchored upper body; keep both elbows heavy on the mat.
- Swinging fast from side to side: momentum carries the hips and the rotators get a bounce, not a contraction; take two seconds per side.
- Piking the hips up as you twist: it shortens the lever and hides weakness; keep the hips in line with the shoulders.
- Holding the breath: the ribs flare, the brace fails, and the lower back extends; breathe out on each dip.
What Are the Best Plank Hip Twist Variations?
- High plank hip twist: performed on the hands, which reduces the range, good for beginners.
- Feet-elevated plank hip twist: feet on a bench increases the load through the shoulders and abs.
- Side plank hip drop: a lateral version that loads one oblique at a time.
- Single leg plank hip twist: one foot lifted off the floor turns each twist into a balance problem for the planted hip.
- Suspension trainer plank hip twist: feet in the straps let the hips swing, raising the anti-rotation demand.
How Do You Progress the Plank Hip Twist?
- There is no external load to add; move from a forearm plank to feet elevated on a bench, then to a single foot, once 20 twists per side are easy.
- Build from 8 to 15 twists per side before making any other change.
- Add a set per week, from 2 sets up to 4.
- Slow the dip to a three-second lower and pause two seconds at the bottom of each side.
How Should You Program the Plank Hip Twist?
Program the plank hip twist as a core accessory at the end of a session, after your compound lifts, or as a circuit station. Two to three sessions per week is enough. Do 3 sets of 10 to 15 twists per side, or 30 to 45 seconds of twisting, with 45 to 60 seconds of rest. Pair it with an anti-extension movement such as a dead bug. Stop the set when the hips start sagging.
