Isometric Wipers
Isometric wipers combine a static top-of-push-up hold with a side-to-side hip movement, like windshield wipers, while your upper body stays braced. Your chest, shoulders, and triceps do isometric work to keep your arms and torso rigid, while your obliques and abs do the moving work of rocking your hips side to side. It's a bodyweight exercise that suits anyone who already owns a solid plank and wants to add a rotational core challenge without any equipment.
Why it works
Holding the top of a push-up position loads your chest, shoulders, and triceps isometrically, meaning the muscle length stays constant while they resist your bodyweight and keep your arms locked out. Layering the hip wiper motion on top adds a second, dynamic demand: your obliques and deep core muscles have to rotate your hips side to side while your shoulders and arms refuse to budge from that fixed position. That combination, a still upper body against a moving lower body, is what makes this a genuine full-body isometric exercise rather than just a plank variation.
Set up
- Start in a high plank with your hands under your shoulders and your body in one straight line.
- Set your feet a little wider than hip width for stability.
- Brace your core and squeeze your glutes before you start moving your hips.
- Keep your neck neutral, looking slightly ahead of your hands rather than straight down.
How to do it
- Hold the top push-up position with your arms locked and your chest, shoulders, and triceps braced.
- Rock your hips and legs to one side, letting them dip partway toward the floor without touching it.
- Bring your hips back through center and rock to the other side.
- Keep your shoulders and arms completely still throughout, only your hips and legs move.
- Continue rocking side to side for your target time or rep count.
- Reset to a neutral plank if your hips start sagging or your shoulders begin shaking.
Form cues
- Keep your shoulders stacked directly over your wrists the entire time.
- Let the movement come from your hips and obliques, not your shoulders swaying.
- Squeeze your glutes to protect your lower back as your hips rotate.
- Move with control on each side rather than swinging quickly.
Breathing: Breathe steadily through the whole set, exhaling as your hips rotate to each side rather than holding your breath through the movement.
Common mistakes
Letting the hips sag toward the floor between wipes
Fix: Brace your core and squeeze your glutes throughout, treating the hold between wipes just as seriously as a strict plank.
Moving the shoulders or rocking through the arms instead of the hips
Fix: Keep your shoulders stacked over your wrists and isolate the side-to-side motion to your hips and legs.
Letting the legs drop all the way to the floor on each side
Fix: Stop the rotation just before your legs touch down, so your obliques stay under tension the whole time.
Rushing through the reps with momentum instead of control
Fix: Slow the tempo down and pause briefly at the center before rotating to the other side.
How to program it
- Two or three sets of 8 to 12 total wipes, meaning 4 to 6 per side, work well once you can already hold a strict plank for 30 seconds.
- This is core and shoulder accessory work, so it fits well near the end of a core circuit or a full body session rather than as a main lift.
- Two or three times a week is enough, since the isometric shoulder hold and the rotating core work both add up in fatigue faster than they look.
- If your form breaks down before you hit your target reps, shorten the set rather than letting your hips sag through the last few.
Safety notes
- Build a solid strict plank before adding the wiper motion, since the moving hips demand more shoulder stability than a static hold.
- Stop if you feel sharp pain in your wrists, and consider using push-up handles or fists if wrist extension bothers you.
- Keep your lower back from arching by keeping your glutes and abs engaged throughout the set.

Frequently asked questions
How many isometric wipers should I do per set?
8 to 12 total wipes, split evenly between both sides, is a solid target for two or three sets once your plank is solid.
Do I need to touch the floor with my legs on each wipe?
No, stop just before your legs touch down so your obliques stay under tension the entire rep, rather than resting at the bottom of each wipe.
What should I master before trying isometric wipers?
A strict plank held for at least 30 seconds with no hip sag is a good baseline, since the wiper motion adds extra shoulder and core demand on top of that hold.
What can I do if the top push-up position hurts my wrists?
Try push-up handles or making fists instead of flat palms, or substitute a reverse crunch, which trains a similar rotating core pattern while lying on the floor.
What muscles does this exercise actually train?
Your chest, shoulders, and triceps hold the top position isometrically, while your obliques and abs do the moving work of rotating your hips side to side.
