Hollow Body Hold
Hold a rounded supine core position with the lower back gently pressed into the floor and the arms and legs extended only as far as control allows.
Overview
Hollow Body Hold is a static anterior-core exercise on Flexor. You lie on your back, lightly round the upper trunk, and extend the arms and legs while keeping the lower back in contact with the floor.
What Hollow Body Hold targets
The rectus abdominis and deeper abdominal stabilisers work to keep the ribs and pelvis connected. The hip flexors assist as the legs extend, but the abdominal brace should prevent the lower back from arching.
Why add Hollow Body Hold to your routine
The hold teaches anti-extension control that carries into hollow rocks, dead-bug variations, planks, and many bodyweight strength movements.
- Static core work with no equipment.
- Easy to regress by bending the knees or keeping the arms forward.
- Easy to progress by extending the legs lower or reaching the arms overhead.
Who it is for
It suits intermediate movers who can maintain a comfortable lower-back position during floor-based core training. Beginners can use a tucked-knee version.
When to do it
Use it in a core-strength or movement-preparation block for short, high-quality holds.
Hollow Body Hold is a static hollow hold and core-bracing exercise performed on the back. Curl the shoulders slightly off the floor, keep the ribs drawn toward the pelvis, and extend the arms and legs without allowing the lower back to lift.
Setup cue
Lie on your back with knees bent and feet lifted. Exhale, press the lower back gently into the floor, lift the shoulder blades, then extend the arms and legs only as far as you can keep that position.
Practice notes
In Flexor, Hollow Body Hold is typically prescribed as about 45 sec per round, 1 rep, and 1 set. Adjust the dosage to what feels sustainable, breathe steadily, and ease off if anything feels sharp or unsafe.
Guidance
How to perform, tips, mistakes, safety notes, and benefits for Hollow Body Hold.
Follow these cues in order. Move with control and stay in a comfortable range.
- Lie on your back with the knees bent, feet off the floor, and arms reaching toward the thighs.
- Exhale, gently press the lower back into the floor, and lift the head and shoulder blades without pulling on the neck.
- Extend the legs away from the body only as far as you can keep the lower back heavy against the floor.
- Reach the arms overhead or keep them beside the thighs, choosing the position that lets the ribs stay controlled.
- Hold with quiet breathing, then bend the knees and lower the shoulders before the back begins to arch.
Cues that help the movement stay smoother and more controlled.
- Keep the lower ribs moving toward the pelvis rather than flaring toward the ceiling.
- Choose a higher leg position when the lower back starts to lose contact with the floor.
- Keep the chin slightly tucked and look toward the thighs to avoid straining the neck.
Patterns to watch for so the shape stays clearer.
- Lowering the legs so far that the lower back arches away from the floor.
- Holding the breath or bearing down instead of maintaining a quiet controlled exhale.
- Pulling the head forward with neck tension rather than lifting from the upper trunk.
Keep things comfortable and stop if something feels wrong.
- Stop if you feel sharp pain, numbness, tingling, dizziness, or symptoms that radiate.
- Stay within a comfortable, controlled range; muscular effort or mild stretch tension should not become pain.
- Move smoothly without bouncing, jerking, or forcing the range.
Why people include this movement in their practice.
- Builds isometric strength and endurance through the anterior core.
- Practises resisting lower-back extension while the arms and legs move away from the centre of the body.
- Provides a scalable foundation for hollow rocks, dead-bug progressions, and controlled gymnastics-style core work.
