The hollow body hold with single arm press is a core exercise performed lying in a hollow position with a light dumbbell pressed by one arm, loading the abs against extension and rotation. Where the plainhollow holdonly fights the arch, moving one loaded arm off the midline also pulls the trunk toward the working side, so the obliques have to hold the shoulders square while the rectus keeps the ribs down. The weight is light on purpose: the press is a disturbance, not a chest exercise. Coaches program it as a core accessory after the main lifts.
What Muscles Does the Hollow Body Hold with Single Arm Press Work?
- Primary: Rectus abdominis (six-pack), transverse abdominis
- Secondary: External and internal obliques, anterior deltoid, triceps brachii
- Tertiary: Hip flexors (iliopsoas), quadriceps, serratus anterior
How Do You Set Up for the Hollow Body Hold with Single Arm Press?
Pick a dumbbell you could press for 20 easy reps. Lie on your back on a mat, legs straight and together, toes pointed, with the dumbbell held at your right shoulder, elbow bent and pointing at the floor. Reach the left arm overhead along the mat. Tuck your pelvis, press the lower back flat, then lift the legs and shoulder blades into a shallow hollow curve with the chin tucked.
How Do You Perform the Hollow Body Hold with Single Arm Press?
- Set the hollow with the lower back flat, legs a foot off the mat and shoulder blades clear of the floor.
- Press the dumbbell straight up over the right shoulder, keeping the left arm reaching long overhead.
- Stop at lockout when the arm is vertical and the dumbbell sits directly above the shoulder joint.
- Hold one count at the top while checking that both shoulders stay level and the hips have not turned.
- Lower the dumbbell back to the shoulder over a slow two-count without letting the elbow touch the mat.
- Repeat for the set, then rest flat, switch the dumbbell to the left hand and rebuild the hollow.
What Are the Key Form Cues?
- Shoulders stay square: as the dumbbell rises, the working shoulder wants to lift toward the ceiling; press the opposite shoulder blade down to keep the chest flat.
- Ribs down before the press: pull the ribcage toward the pelvis a beat before each rep, so the arm moves on a fixed trunk.
- Keep the free arm reaching long overhead so the lever does not shorten.
- Feel the side of the trunk opposite the dumbbell working as the arm leaves the shoulder.
- Squeeze the thighs together so the legs stay one solid lever throughout.
What Are the Most Common Mistakes?
- Choosing a dumbbell heavy enough to feel like a floor press: the lower back arches to brace and the hollow is gone, so drop to a weight you could press for 20 reps.
- Rolling toward the working arm: that hip and shoulder lift off the mat and the obliques stop working, so pause at lockout and level the shoulders.
- Letting the legs sink late in the set: the lumbar spine peels off the mat under the leg lever and the hip flexors take over, so raise the legs or end the set.
- Dropping the free arm to the mat: the lever shortens and the trunk gets help, so keep the biceps by the ear.
- Pressing at an angle toward the midline: the dumbbell ends over the face and the shoulder rotates in, so drive it straight over the shoulder joint.
What Are the Best Hollow Body Hold with Single Arm Press Variations?
- Hollow body hold: the same shape with no dumbbell, the regression.
- Hollow body single arm dumbbell floor press: the upper arm rests on the floor and the load goes up, a chest exercise.
- Hollow body hold with sweep: the arm sweeps in an arc instead of pressing, no dumbbell needed.
- Hollow hold with alternating press: one dumbbell in each hand pressed in turn, so the trunk load switches sides every rep.
- Hollow hold with single arm kettlebell press: the offset bell adds a wrist and shoulder stability demand.
How Do You Progress the Hollow Body Hold with Single Arm Press?
- Move up 5 pounds once every rep locks out with the shoulders level and the lower back flat.
- Build from 6 reps per arm to 12 before adding load.
- Add a set per week, from 2 up to 4 per arm.
- Add a two-second hold at lockout, or slow the lowering to three counts, before the next jump.
How Should You Program the Hollow Body Hold with Single Arm Press?
Program the hollow body hold with single arm press as a core accessory at the end of a session, after the main lifts and any heavy pressing, 2 to 3 times per week. Do 2 to 4 sets of 6 to 12 reps per arm with 45 to 60 seconds of rest. Pair it with a side plank so the trunk also trains against lateral flexion. Switch arms before fatigue changes the hollow.
