A pike is a handstand folded at the waist: the hips sit behind the shoulders and the legs hang forward of them, so the body makes a shallow L instead of a line.
What it looks like
From the side there is a visible corner at the hip. The feet are in front of the line of the wrists, and the shape looks like it is on its way back down even when the hold is steady.
Why it happens
Usually the shoulders. When the arms cannot line up with the torso, folding at the hip is the only way left to keep the mass over the hands — so a pike is a balance solution, not laziness. It is also what a short kick-up leaves behind, and what tight hamstrings pull you into the moment you stop thinking about your legs.
What it costs you
A piked handstand is shorter than it looks and heavier than it should be: with the hips behind the hands, the shoulders carry the shape instead of the skeleton. Every straight-line skill above it — the press, the walk, the one-arm — needs the angle open first.
How to fix it
Push the floor away and reach your hips up over your shoulders rather than kicking the legs harder. Chest-to-wall holds with your belly on the wall stop you piking to balance, and hip-opener presses teach the last few degrees under load.
Drills that fix it
Chest-to-wall hold
5 × 30–60s. Film one set from the side.
Belly and toes to the wall, hands 10–15cm out, ribs down, push tall through the shoulders. Only your toes touch.
Pike-to-straight at the wall
5 × 5 slow transitions.
Feet on the wall in a pike, hips over shoulders. Slowly lift one leg to vertical, then the other, finding the straight line.
How Nstand measures it
The same measurement as the arch, in the other direction: the angle at your hips between torso and legs, signed by the way your chest points. More than 8° of fold, averaged over the hold, is called piked hips.
It is a camera and some geometry. It does not replace a coach, a gym or an academy, it cannot see your wrists, your history or what you are about to land on, and it is wrong sometimes. Handstands can injure you. What you do on your hands is your decision and your risk: warm up, train where a fall is safe, and stop when something hurts.
