Letting the lower back arch off the floor.
Fix. Bend the knees or raise the legs higher to make it easier — keep the back pinned.
Hollow Body Hold: setup, top form cues, common mistakes, and how to program it for strength, hypertrophy, or conditioning. Used in The Training Notes.
The hollow body hold lifts the legs and shoulders off the floor while pressing the lower back flat into it. It teaches the trunk shape that protects the spine in every overhead lift and gymnastic skill.
When to pick it. Pick the hollow body hold when you want to fix the lower-back arch in overhead pressing, before any gymnastic work, or as a daily 30s warm-up brace.
Primary muscle: Core. Secondary: Hip flexors. Equipment: Bodyweight. Difficulty: intermediate.
Fix. Bend the knees or raise the legs higher to make it easier — keep the back pinned.
Fix. End the set the moment the lower back lifts. 3 × 20s clean > 1 × 60s sloppy.
Fix. End the set when ribs flare or the lower back starts to arch. A 30s perfect plank > 90s sagging.
Fix. Brace and breathe shallowly through the nose. Apnea kills tension faster than fatigue does.
Prescription. 2–3 sets of 30–45s, 2× per week.
Enough to maintain trunk stability without stealing recovery from the main lifts.
Prescription. 3–5 sets of 15–20s with maximum tension, 1× per week.
RKC-style holds build the kind of brace that transfers to heavy lifts.
Prescription. 3–4 sets × 30–40m heavy, 1× per week as a finisher.
Trains grip, traps, and full-body bracing in a single move.
The Hollow Body Hold trains your rectus abdominis to create spinal flexion, which is a different task than the anti-extension challenge of a plank. While a plank braces your core in a neutral position, the Hollow Body Hold requires you to actively shorten the space between your pelvis and your ribcage. The primary goal is to achieve a posterior pelvic tilt, pressing your lumbar spine flat against the floor with zero space. This position directly opposes the arched-back posture common in daily life and in lifting errors like rib flare during an overhead press. Your objective should be to accumulate quality time under tension, performing multiple sets of 30- to 60-second holds. The set ends the moment your lower back lifts off the floor, as this indicates a loss of the target position and a shift in muscular engagement.
Programming nuance. You can use the Hollow Body Hold as a positional primer before your main lifts. Instead of treating it as a finisher, perform a sub-maximal 20-second hold immediately before a set of pull-ups or overhead presses. This activates the targeted core musculature and provides immediate tactile feedback for maintaining a rigid torso. It helps you learn to prevent lumbar extension and transfer force more effectively during the compound lift that follows, improving the quality of each repetition.

End the set when the lower back arches, not when you 'fail'. Quality > duration always for core work.
The Hollow Body Hold is a intermediate core exercise using bodyweight. It's part of the core pattern.
Anyone training the core pattern with access to bodyweight. It also suits lifters aliased searches like hollow hold.
Not as a first exercise in the core pattern. Build to it from an easier variation before adding load.
Once or twice a week in most programs. Frequency depends on the training goal, the total weekly volume for core, and how much other work is already stressing the same pattern.
