Hollow Hold

The hollow hold is a gymnastics-rooted isometric: lower back pressed into the floor, arms and legs floating, the whole body set in one rigid dish shape. It suits trainees who already own a clean plank and want a stricter test of anti-extension bracing. Coached by Maddy (NASM-CPT) — these are the exact form cues he gives on every client's first week.

Sets & reps by goal

Goal	Sets × Reps	Rest
Strength	4 holds × 10–20 s	90 s – 2 min
Muscle	3–4 holds × 20–40 s	60–90 s
Endurance	3 holds × 40–60 s	45–60 s

Level — Advanced

Advanced — earn it through tuck and single-leg versions before floating both legs low.

Proper form — 5 cues

Press your lower back into the floor first — the entire hold is built on that contact.
Reach both arms overhead beside your ears and hover the legs a few inches up, heels together.
Tuck the ribs down toward the pelvis; the shape is a shallow dish, never an arch.
Point the toes and squeeze the thighs together so the legs move as one unit.
The moment the lower back peels up, raise the legs higher or bend the knees — shrink the lever, keep the shape.

Breathing: Short, steady breaths behind a braced trunk; never trade back position for a bigger inhale.

The 3 mistakes Maddy corrects most

Lower back arching off the floor. The hold stops training anti-extension and starts loading the lumbar spine instead. Fix: Shorten the lever — bend the knees or lift the legs toward 45° until back contact is constant.

Chin jammed into the chest. Neck strain fakes the position while the trunk does less of the work. Fix: Keep the head between the arms, eyes on the ceiling just past the knees.

Holding one giant breath. The brace collapses the instant the air finally leaves. Fix: Take short, shallow breaths behind a constant abdominal brace.

Common questions

Can beginners do a hollow hold?

Not usually in the full version — it is filed as advanced for a reason. Start with a bent-knee tuck hold, arms by your sides, lower back pressed down. Once 30 seconds feels controlled without the back lifting, straighten one leg, then both, and only then reach the arms overhead.

Hollow hold vs plank — which is better for abs?

They train the same anti-extension job from opposite sides. The plank fights gravity with the forearms supporting you; the hollow removes support and makes the abs create the shape alone. Most programs use both — plank for time under load, hollow for stricter positioning and carryover to hanging work.

How long should I hold a hollow hold?

Only as long as the lower back stays glued down — a crisp 15-second hold beats a sagging minute. Accumulate 60–90 seconds of quality work per session across three to five sets, then progress by lengthening the lever, not just the clock.
