The hollow hold is a gymnastic core position: lying on your back, arms and legs extended and slightly raised, lower back pressed into the floor. It builds isometric core strength that translates directly to gymnastics, calisthenics and full-body athletic control.
What it is
The hollow hold is a static core exercise. Lying supine, the lifter raises the arms overhead, lifts the legs off the floor, and presses the lower back into the ground so the body forms a shallow banana shape — arms and legs elevated, midsection hollow. The rectus abdominis and hip flexors hold the position isometrically.
Muscles worked
| Muscle | Contribution |
|---|---|
| Rectus abdominis | ~45 % |
| Hip flexors, quads | ~30 % |
| Obliques, transverse ab | ~15 % |
| Shoulders | ~10 % |
How to hollow hold: 5 steps
-
Lie supine
**Lie on back, arms extended overhead, legs straight.**
-
Press lower back down
**Actively press lumbar spine into the floor.**
-
Lift arms and legs
**Raise arms and legs a few inches** — body forms banana.
-
Brace
**Squeeze abs and glutes, hold the position.**
-
Time the hold
Hold for target duration. Breathe through the diaphragm.
How it differs from plank
- Supine, not prone. Face-up instead of face-down.
- Lower-back pressure focus. Actively press the lower back into the floor.
- Arms extended overhead. Adds shoulder demand.
- Foundation for gymnastic skills. Hollow position underpins muscle-ups, kipping, ring work.
Common mistakes
When to use this variation
Use hollow holds as isometric core training and gymnastic prep. Program 3-4 sets of 20-45 second holds. Foundation exercise for anyone learning calisthenics or gymnastic skills.
FAQ
How long to hold?
Start at 15-20 seconds. Build to 45-60 seconds. Beyond 60 sec becomes endurance rather than strength.
Lower back lifting off floor — what to do?
Bend the knees to tuck position. Reduce leverage until lower back stays down.
Hollow hold or plank?
Both are static. Hollow trains anti-extension supine (gymnastic); plank trains anti-extension prone. Use both.
