The Narrow Leg Bench Bridge is a bodyweight plank hold that targets the rectus abdominis, with the obliques, quadriceps, tensor fasciae latae, front deltoids, and serratus anterior working to keep your body rigid. Elevating your feet on a bench and bringing them together narrows your base, so your core has to fight both sagging and rotation. It is a natural progression once the standard floor plank feels easy.
How to do the Narrow Leg Bench Bridge
- 1Set a flat bench behind you and kneel on the floor about a forearm's length in front of it, facing away.
- 2Place both forearms on the floor with your elbows stacked directly under your shoulders and your hands flat or lightly clasped.
- 3Step your feet up onto the bench one at a time, resting your toes on the surface until your body forms a straight line from head to heels.
- 4Bring your feet together until your ankles touch, or sit no more than an inch apart — this narrow base is what separates the drill from a standard bench bridge.
- 5Brace your abs as if bracing for a light punch and squeeze your quads to keep your knees straight.
- 6Press your forearms into the floor and push your shoulders away from your ears so your upper back stays broad instead of collapsing between the shoulder blades.
- 7Hold the position for your target time (20–45 seconds), breathing steadily and resisting any sag in the hips or twist toward either side.
- 8Step your feet down one at a time and lower your knees to the floor to finish the set.
Form tips
- Tuck your pelvis slightly so your lower back stays flat — elevating your feet increases the pull toward lumbar extension, and a neutral pelvis is what keeps the load on the rectus abdominis.
- Expect the narrow stance to make you wobble side to side; that lateral instability is the obliques' job, so let them work rather than widening your feet to escape it.
- Keep your gaze at the floor just in front of your hands so your neck stays in line with your spine.
- Raise the bench height to make the hold harder: the further your feet sit above your shoulders, the more of your bodyweight shifts onto your upper body and core.
- End the set when your hips start to drop, not when the timer says so — 25 clean seconds beats 45 seconds of sagging.
Common mistakes
- Letting the hips sag toward the floor: this dumps tension off the rectus abdominis and loads the lumbar spine instead, which is where plank-induced back soreness usually comes from.
- Piking the hips up toward the ceiling: it feels easier because it shortens the lever, but it takes the abs out of the position and turns the hold into a shoulder rest.
- Letting the feet drift apart mid-set: widening the base removes the anti-rotation demand on the obliques and quietly turns this back into a standard bench bridge.
- Holding your breath to stay rigid: it fakes stiffness for a few seconds, then raises blood pressure and forces you to cut the set short.
- Letting the chest sink between the shoulder blades: the serratus anterior stops supporting the shoulder and the load hangs on passive joint structures instead of muscle.
Frequently asked questions
What muscles does the Narrow Leg Bench Bridge work?
It targets the rectus abdominis. The obliques resist rotation from the narrow base, the quadriceps and tensor fasciae latae keep the knees and hips extended, and the front deltoids and serratus anterior support your bodyweight over your forearms.
Is the Narrow Leg Bench Bridge a glute exercise?
No. Despite the word bridge in the name, this is a front plank rather than a hip-thrust style glute bridge — you hold a straight line face-down on your forearms with your feet elevated. The work lands on the abs and trunk stabilizers, not the glutes.
How is this different from a regular plank?
Two things change. Elevating your feet on a bench shifts more of your bodyweight forward onto your upper body and core, and bringing your feet together narrows your base of support so your obliques must fight rotation the whole time.
How long should I hold the Narrow Leg Bench Bridge?
Two to four sets of 20–45 seconds is a sensible default. Treat position quality as the limit: end the set as soon as your hips start to sag or your feet drift apart, even if you are short of the target time.
Is the Narrow Leg Bench Bridge good for beginners?
Not as a starting point. Build to a clean 45-second floor plank first, then progress to a bench bridge with your feet hip-width apart, and only narrow your stance once you can hold that without your hips dropping or twisting.
