Film yourself pumping and look at one thing: when you sink into a turn, what actually bends?
For a huge number of riders the honest answer is the waist. Chest folds toward the board, butt pushes out behind, and the knees — the joints that were supposed to do this job — stay nearly straight. Riders everywhere know it by its unglamorous name: the poo stance. It shows up in surfing, snowboarding, and surfskate alike, and it's worth catching early because it quietly caps every other part of your riding.
Why the waist-fold costs so much
Getting low is right. The pump lives in compression and extension — sink into the turn, drive out of it. The poo stance is what happens when the body finds a shortcut to "low" that skips the legs entirely.
The trouble is that a waist-fold produces depth without producing spring. Knees that stay near straight have nothing loaded in them — no compression to extend out of, so the turn gets no drive. Worse, folding the chest down shifts pressure off the rail at exactly the moment the turn needs it most. On a real wave, this is the posture that washes out a bottom turn; on the surfskate, it's the reason your carves look deep but feel dead.
The signature on video is unmistakable: a lot of forward trunk lean paired with knees that barely change angle. Big fold, small bend. If your knees are cycling deeply too, forward lean is just athletic — plenty of strong riders get their chest down over a genuinely compressed base. It's lean WITHOUT knee travel that marks the poo stance. CoachVision reads both numbers from a side-on phone clip — trunk lean at your deepest compression, and how much your knees actually cycle — so you can see in one screen which kind of low you are.
The fix — swap the hinge, keep the depth
Here's the encouraging part: you don't need to change how low you get. You only need to change where the bend happens. Same depth, different hinge.
The feel to chase: knees track out over your toes, hips stay tucked underneath your shoulders instead of drifting back, chest stays proud. Think of your torso as one calm unit riding an elevator that your legs operate. When it's right, your eyes stay level through the whole compression instead of diving toward the deck.
The drill — Hips-Forward Reset
Do this before you roll a single meter.
Stand on your board on grass or carpet and build the position statically: sink down by bending the knees only — knees over toes, hips under shoulders, chest proud, eyes on the horizon. Hold it for a full 20 seconds. Feel where the work is: it should burn in the thighs, not pull in the lower back. If your back is doing the talking, your hips have snuck backward — tuck them under and sink again.
Three holds, then three easy runs trying to carry the exact same shape into your carves. That's the whole session assignment: 3 holds, 3 runs, every session this week.
The position will feel like more effort at first, because it is — your legs are finally carrying what your waist was faking. Give it a week, then film a side-on run and compare. When the bend moves into your knees, everything downstream — the pump, the carves, the drive out of every turn — gets its pressure back at once.
