Foam Roller Body Saw

With forearms planted on a roller, you slide the whole plank forward and back a few inches at a time, so the abs fight the same lengthening stress as a rollout but from a more locked-in elbow position. The range looks tiny; done slowly with level hips, ten reps is legitimately hard.
How to do the Foam Roller Body Saw
- Start in a plank position with your forearms on the roller and your body in a straight line.
- Engage your core and slowly roll the roller forward, extending your body as far as you can while maintaining control.
- Pause for a moment at the furthest point, then slowly roll the roller back towards your starting position.
- Repeat for the desired number of repetitions.
Tip: Exhale slowly as you roll out and keep the ribs pulled down toward the pelvis the entire time.

Common mistakes
- Hips sagging at the bottom — if your lower back arches as the wheel rolls out, you have gone past the range your abs can control; shorten the rollout and stop at the point where your hips still stay tucked.
- Hinging at the hips — pushing your backside back toward your heels on the return turns it into a hip hinge; keep the hips locked in line with the torso and pull with the abs.
- Reaching with the arms — leading with the arms turns it into a lat exercise; think of moving the whole body as one rigid plank that happens to lengthen.
- Skipping the posterior tilt — before you roll, squeeze the glutes and tuck the pelvis slightly so the abs are braced before the load arrives.
Sets, reps and where it fits
| Goal | Sets × reps | Rest |
|---|---|---|
| Strength | 3 × 8–12 | 60 s |
| Endurance | 2–3 × 15–25 | 45 s |
Rollouts belong toward the end of a session, after heavy lifts but while you can still brace well. Superset them with hanging knee raises or a plank variation so the core work is done in one block.

Frequently asked questions
What muscles does the Foam Roller Body Saw work?
The Foam Roller Body Saw primarily works the abs. It also involves the delts and triceps, which assist the movement and stabilise the joints.
Is the Foam Roller Body Saw good for beginners?
Not as a starting point. The Foam Roller Body Saw is rated advanced because it demands strength, mobility or coordination that takes time to build. Beginners should work up to it through the easier variations listed on this page.
What can I do instead of the Foam Roller Body Saw?
If you cannot do the Foam Roller Body Saw, try the Plank Shoulder Tap or the Bench Assisted Barbell Rollout. Each of them trains the abs through a similar movement, so you can swap them in without changing the rest of the workout.
How many sets and reps should I do?
It depends on your goal. For the Foam Roller Body Saw, a sensible starting point is strength: 3 × 8–12 with 60 s rest; endurance: 2–3 × 15–25 with 45 s rest. Train it at the end of a session or pair it with a lower-body lift as active rest.
