Hollow Holds
A gymnastics hollow-body hold that locks the anterior core into one rigid dish, pressing the lower back flat — a foundational stability skill.

Target muscles
The rectus abdominis and transverse abdominis work isometrically to flatten the lower back into the floor and hold the dished shape, with the hip flexors assisting to keep the legs raised. The deep core learns to keep the rib cage and pelvis tied together — exactly the bracing pattern that transfers to handstands, leg raises, kipping work and every heavy lift overhead. It is a position as much as a muscle, and the whole front of the trunk is engaged.
How to perform
Setup
Lie on your back with the arms extended overhead and the legs straight. Before lifting anything, tilt the pelvis and brace the abs to press the lower back firmly into the floor. This flat-back position is the non-negotiable foundation of the hold.
Execution
Keeping the lower back glued down, lift the shoulder blades, arms and legs a few inches off the floor so the body forms a shallow banana or dish shape. Keep the arms by the ears, the legs straight and squeezed together, and the toes pointed. If the lower back peels off the floor, you have lost the position — lower the limbs or bend the knees until you can keep it flat. Breathe in short, controlled breaths and hold the rigid shape for time, fighting to keep everything locked together.
Common mistakes
- Letting the lower back arch off the floor, which collapses the position and loads the spine.
- Raising the legs too high so the hips bend and the abs disengage.
- Holding the breath, which makes the brace impossible to sustain for any length.
- Bending the knees or dropping the arms to cheat the difficulty without scaling deliberately.
Progressions and regressions
Regress by tucking the knees, bending the arms across the chest, or raising the legs higher to shorten the lever until the back stays flat. Progress by extending the limbs fully, adding small hollow rocks for a dynamic version, or holding a light object overhead. The tuck-to-full progression is the standard path gymnasts use.
Programming notes
Program it as core stability work, three to five sets of fifteen to forty-five second holds, or as a quality primer before gymnastics and overhead training. Stop the instant the lower back lifts — a clean twenty seconds beats a broken forty. It is a skill as much as a strength exercise, so frequent short exposures build it faster than occasional long grinds.
