Pro-level carving: understand angulation, outside-ski pressure and edge angle, and analyse them in slow motion – with forces up to 5× body weight.
## Introduction What separates a clean carving turn from one that skids out? Straight talk: a single control variable. You create the edge angle from your ankle, knee and hip joints (angulation) and progressively load the outside ski — instead of leaning your whole body into the turn (inclination). Elite measurements show why that's so decisive: during the steering phase the outside leg carries roughly 114–126 percent of body weight, the inside leg only about 67–76 percent; in racing, peak ground reaction forces shoot up to five times your body weight. Shift this load onto the inside leg or into a trunk rotation and you lose grip — and, at worst, risk the slip-catch, the most common ACL mechanism. Your goal is not more strength but more precise force direction: the right movement at the right time on the right ski.
## What You Need - A solid parallel and carving base on blue and red slopes - A smartphone/camera for slow-motion footage (240 fps ideal) - Optional: edge-angle/force feedback via wearable or app - Well-tuned skis (sharp edges, appropriate sidecut) and a helmet - A professionally set binding Z value
## Step by Step ### 1. Build outside-ski pressure progressively The turn belongs to the outside ski. Build pressure progressively from the start to the end of the turn, moving the pressure from the forefoot to the heel as you go. This controls ski deflection and keeps the edge carving rather than skidding.
### 2. Steer with angulation, not inclination Create the edge angle from the lower joints and angle the hip toward the valley while the upper body compensates upright. This keeps your centre of mass over the outside ski. Pure inclination (leaning in) sooner or later tips you into a loss of pressure.
### 3. Understand radius via edge angle and sidecut The carved radius follows from edge angle and ski sidecut: more edge angle, tighter radius. Use this deliberately – tight radii cost the most energy and speed, especially near the fall line.
### 4. Time the edge-change phase cleanly During the edge change the forces can briefly drop toward zero. This is your window for a flowing edge change and the forward translation of your centre of mass into the new turn. Waste it and you start the new turn in the backseat.
### 5. Analyse objectively on video Film yourself in slow motion from below and from the side. Edge angle and radial force are measurable quality parameters. Check forensically: does the initiation start cleanly from the ankle or from a trunk rotation? Is the outside ski loaded? Is the pressure centred?
## Common Mistakes - Inclination instead of angulation: leaning in without a hip angle → loss of pressure and skidding. - Overloading the inside leg: contradicts the real load distribution. - Backseat during the edge change: wastes the low-force window. - Trunk rotation to initiate: a risky pattern that threatens the ACL in the slip-catch.
## Safety Notes High-speed carving generates enormous forces – the slip-catch loads the ACL in internal rotation and valgus within about 60 milliseconds. Analyse loading angles in slow motion and correct any initiation that comes from a sloppy trunk rotation instead of the ankle. Ski only as fast as you can safely change edges, keep sharp edges and a professionally set Z value.
## Pro Tip During slow-motion review, mentally draw a line through your hip and outside ski. If the line shows your hip dropping inward below the knee (instead of angling toward the valley), you are inclining – exactly the pattern that removes pressure from the outside ski. A deliberate hip angulation of a few degrees brings the grip back.
## FAQ ### What is the difference between angulation and inclination? Inclination is leaning the whole body into the turn; angulation is the deliberate hip angle with which you create the edge angle from the lower joints while the upper body compensates toward the valley. Only angulation keeps the centre of mass over the outside ski and thus the pressure on the carving edge.
### Why is the outside ski so important? Because it carries the load: during the steering phase roughly 114–126 percent of body weight rests on the outside leg, only about 67–76 percent on the inside leg. This asymmetry is technique, not muscle strength – shift the load onto the inside leg and you lose grip and control.
### How much force acts on the legs and knees when carving? In racing, ground reaction forces reach peaks of up to five times body weight, highest in giant slalom. During the steering phase they are far greater than in the edge-change phase, where they can briefly drop toward zero. Recreational skiers stay below this, but the loading pattern is the same.
### How do I analyse my ski technique on video meaningfully? Film in slow motion (ideally 240 fps) from below and from the side and check measurable parameters like edge angle and radial force. Verify three things: whether the initiation comes from the ankle rather than the trunk, whether the outside ski is loaded, and whether the pressure moves from forefoot to heel.
