Hollow body hold to pike compression
Two shapes show up all over the tree: the hollow you hold and the pike you fold into. This chain builds both, from a floor hold at White to slow toes-to-bar at Blue.

The hollow body hold is the base shape of gymnastics. You lie on your back with the lower back pressed into the floor and the ribs pulled down, then lift long arms and legs just off the ground. Pike compression is a different job: folding at the hips, pulling straight legs toward your chest with the abs and hip flexors against the stretch in your hamstrings. One shape keeps you rigid, the other closes the hip angle on command.
Both shapes carry straight into the big skills. The hollow is the line of a clean handstand and the body position of the front lever. Compression is what lifts your heels in an L-sit and a V-sit, and what lets your feet float off the floor in a press to handstand. When those skills stall even though the arms are strong enough, weak compression is often the reason.
The road starts on the floor at White. The Hollow Hold sets the shape, the Tuck Up Crunch and Hollow Body Rocks put it in motion, and the Seated Pike Leg Lift brings in compression. Green raises the demand with the V-Up and the Standing Pike Compression. Blue takes it to the bar with the Hanging Pike Compression, slow toes-to-bar with straight legs.

How to climb it
Move up when you own the standard of your current step, with the lower back down on the hollow steps and the knees locked on the pike steps. Climb it like a ladder: holds from 10s toward 30s, 5 seconds per session, and reps from 3 × 5 toward 3 × 8, one per session. Two or three short sessions a week is enough, at the end of a workout or on a lighter day.
Compression grows when strength and flexibility are trained together. Do the stretch, then go straight into the lifts while the range is fresh. Keep each effort short and sharp: the protocol on this page is built around 10-second lifts. To keep score, mark your current step as training on the BARCROSS tree, then as achieved once the standard is yours.
Form cues
- Protocol: posterior-chain stretch 30–60s → sit, legs straight → hands along the legs (further = harder) → lift feet 10s × 4–5
Common mistakes
- Holding your breath: a hollow you can only keep without breathing is too hard, so take short breaths behind a braced trunk and regress if the shape falls apart.
- Pushing with the chin: your shoulders should rise because the abs curl you, so keep the neck long instead of driving the head forward.
- Soft knees in pike work: a bent knee turns compression into a tuck, so keep the legs locked and accept a smaller lift.
- Leaning back on seated lifts: opening the hip angle makes the lift easier and skips the compression you came for, so sit tall with the chest over the legs.
- Swinging up to the bar: momentum skips the closed-hip range this chain exists to build, which is why the Blue standard asks for slow reps.
- Stretching without lifting: loose hamstrings alone will not raise your legs, so follow every stretch with active lifts.
Questions
How long should you hold a hollow body hold?
The standard on this chain is 3 × 20–30s. Start where the shape holds cleanly, even if that is 10 seconds, and add 5 seconds per session. Once 30 seconds is solid, move up the chain instead of chasing minutes.
What is pike compression?
It is strength in a closed hip angle: lifting straight legs toward your torso with the abs and hip flexors. Flexibility lets the legs get there, and compression gets them there under your own power. It is often the missing piece for people stuck on the L-sit or the press to handstand.
Why does my lower back lift off the floor in a hollow hold?
Your levers are longer than your current strength. Bend the knees or bring the arms toward your hips until the lower back stays down, then lengthen them again over the coming weeks. The hold only counts while the back is flat.
How do I improve compression for the L-sit?
Train the stretch and the lift in the same session, legs straight and chest tall. Climb from the Seated Pike Leg Lift to the Standing and Hanging Pike Compression steps as each one gets easier. Keep practicing the L-sit itself too: compression lifts the legs, but your shoulders still have to hold you up.
Compression = closing the hip angle. It feeds L-sits, V-sits, presses and pistols.
