📖 Static demo — read-only snapshot
You’re browsing a static build of the Body IQ knowledge graph, so everything loads with no backend. A few things that need the live server are turned off here:
- Global search (sidebar) is disabled — it queries the API.
- The JSON API and the API “Try it” playgroundaren’t included.
- The data is a snapshot — it refreshes only when the demo is rebuilt, not live from the database.
Everything else — the body map, progression ladders, coverage heatmap, exercise finder, and all anatomy/exercise/source pages — works fully. The full app (live search + API + database) runs from the source on GitHub.
Hollow Body Hold
Why Include This
The hollow body hold is an anti-extension trunk-stabilization isometric that trains the rectus abdominis, obliques, and transversus abdominis to resist lumbar hyperextension while the hip flexors hold the legs elevated — the exact demand needed to maintain a neutral/braced spine during lifting, carrying, and overhead tasks. Trunk/core stabilization exercise broadly has moderate evidence for reducing pain and disability in chronic non-specific low back pain, and EMG work consistently shows dished, long-lever supine holds produce high abdominal activation. However, evidence specific to the hollow body hold as a named exercise is limited (it comes largely from gymnastics and general strength-and-conditioning practice rather than RCTs), so it is best justified mechanistically: it teaches posterior pelvic tilt control, rib-down bracing, and endurance of the anterior core, which are trainable, transferable qualities. Because the load is scalable simply by changing limb lever length, it is a safe, equipment-free home option for building anterior-core endurance.
Evidence basis: limited
Positions & Range of Motion
- Start
- supine on the floor, low back flattened into the ground, arms reaching overhead and legs straight together
- End
- shoulder blades, arms, and straight legs lifted a few inches into a dished, banana-shaped position and held isometrically
- Range of Motion
- isometric hold — minimal joint excursion; the low back is kept pinned flat to resist lumbar extension (anti-extension)
How to Perform
Lie supine on the floor (or an exercise mat), flatten your low back into the ground, then lift the shoulder blades, arms, and straight legs a few inches and hold that dished, banana-shaped position isometrically.

Coaching Cues
- 1
Press your low back flat into the floor so there is no gap under your spine before you lift anything.
(internal) - 2
Draw your ribs down toward your pelvis and keep them there — do not let the ribcage flare.
(internal) - 3
Reach your fingertips and toes long in opposite directions, as if being stretched between two walls.
(external) - 4
Lower the arms and legs only as far as you can keep the low back pinned; raise them if the back arches.

Evidence-Based Dosing & EMG Data
Hold 20-30 seconds for 3-4 sets, resting 45-60 seconds between; progress by adding time (up to ~45-60 s) or lengthening the limb levers before adding sets. Perform 3-4 days per week. Stop or regress the moment the low back lifts off the floor.
Dished, long-lever supine holds elicit high rectus abdominis and oblique activation; abdominal EMG rises as the arm/leg levers lengthen and the legs are lowered toward the floor, while erector spinae stays relatively quiet as an isometric anti-extension task.

Easier Variations ↓
Tuck (bent-knee) hollow hold
Keep the knees bent and thighs stacked over the hips to shorten the lever, reducing the anti-extension load while still training the same bracing pattern.
Arms-down / single-limb hollow
Rest the arms alongside the body and extend only one leg at a time, halving the lever load so a beginner can keep the low back flat.
Harder Variations ↑
Long-lever low hold
Extend arms fully overhead and lower straight legs closer to the floor, increasing the anti-extension moment while maintaining a flat low back and longer hold times.
Hollow body rock
From the full hollow position, rock the whole rigid body back and forth in a smooth arc, adding a dynamic anti-extension endurance and control challenge.
