Barbell Ab Rollout
Also works: Lower Back · Shoulders
From a push-up position with your hands on a lightly loaded Olympic bar, you pike your hips up and roll the bar back toward your feet, then roll it forward until your body is a straight line again. Standing on your feet rather than kneeling means the abs control the full length of your body against gravity from the first rep.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Load an Olympic bar with the smallest plates that let it roll freely — 2.5 kg a side is enough. Bare 25 mm plates will not clear the floor.
- Check the bar is on a surface that lets it roll straight; a rubber platform with a seam will steer it sideways mid-rep.
- Take a shoulder-width overhand grip and set up in a push-up position with hands on the bar, feet hip-width.
- Squeeze your glutes and tuck your ribs down so your body is a straight line from heels to head before the bar moves.
- Warm up the position first: hold the plank on the bar for 20 seconds and make sure your wrists tolerate it.
Every rep
Breathing & tempo — Inhale and brace as you roll the bar forward, exhale as you drive the hips back up into the pike. Three seconds out, one second held, one to two seconds back.
Before you load it
- If your lower back is what you feel at the end of the range, stop the set. That sensation means the spine is extending and the abs have already lost, and it is the mechanism behind almost every rollout injury.
- The bar can skid out from under you on a slick floor. Set up on rubber or wedge it against a wall for your first sessions.
Sets, reps & load
Where to start, and what to change when it stops being hard.
Use 2.5-5 kg a side purely so the bar clears the floor and rolls true. Progress by extending how far forward you roll before the hips sag, then by pausing a full second at the plank end, and only then by adding reps. A full extension to a rigid plank with a one-second hold is the marker that you have outgrown the beginner version of this.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Shorten the roll. Place a mat or a wall a hand's width past your longest good rep and use it as a hard stop, then move it out a few centimetres a week.
Keep your wrists under your shoulders as you pike. Film one set from the side; you want the forearms near vertical at the top, not angled back.
Take three seconds on the way out and one full second paused at the pike. If you need speed to return, you have gone past your controllable range.
Chalk a line on the floor at the point where your body is dead straight and make the bar reach it on every rep. The bottom half is where the abs actually get loaded; the pike is the cheap half.
Why bother
Rolling forward from a plank is anti-extension work: the abs are the only thing stopping gravity from dragging your hips to the floor and folding your lower back. Piking the hips back up adds the concentric half, so this version trains both directions of the same job in one rep instead of just the resisted lowering.
Arm angle decides who does the work. If your arms stay roughly perpendicular to the floor as your hips rise, the abs and hip flexors move you. Let the shoulders drift and the movement turns into a lat and front-delt exercise with a mild ab cramp attached — which is what most people are actually doing when they say rollouts hurt their shoulders.
Where it fits
After your main lifts, twice a week, 3-4 sets of 8-12. Do not pair it with heavy deadlifts in the same session if you have to choose — both tax the same trunk bracing, and the rollout is the one that will collapse first and teach you a bad position.
If this one isn't it
No kit, too hard, or too easy — here's where to go instead.

Asked and answered
How much weight should be on the bar?
The smallest plates that let the bar roll — 2.5 kg a side is plenty. The load on the bar is not the resistance; your own bodyweight and the length of the lever are. Adding 20 kg a side changes almost nothing except how hard the bar is to move into position.
Is a barbell better than an ab wheel?
They train the same thing, with two differences. An Olympic bar rolls on bearings and is more stable and more forgiving of a slightly uneven push, while an ab wheel is narrower and harder to keep tracking straight. Use whichever you have; neither is a meaningful upgrade over the other.
My wrists hurt in the push-up position on the bar.
The bar puts your wrists in extension under load. Try a slightly wider grip, warm the wrists up with a 20-second static hold before your first set, or switch to an ab wheel with vertical handles, which keeps the wrist neutral. Pain that persists past a warm-up is a reason to change tool, not to push through.
Should I do this from my feet or my knees?
From the feet is the harder start and the version described here, because your whole body is the lever from rep one. If you cannot hold a straight line for eight reps, drop to knees, earn it there, and come back. Doing sagging reps on your feet trains nothing except lower back tolerance.
