The Stem Christie: Your Bridge From Wedge to Parallel Turn

The stem christie on skis: stem the uphill ski, shift weight, bring the inside ski parallel – with milestones, mistakes and a knee safety note.

Sport: Skifahren · Level: Intermediate

Introduction

In the stem christie you start the turn by stemming the uphill ski outward, shifting weight onto it and then bringing the other ski parallel. It is the intermediate step between wedge turn and parallel turn: you ski the curve almost parallel but still need the wedge to initiate it.

Honest up front: the term "stem christie" does not appear in the DSLV excerpts I read. The teaching-practice topics for instructors lead the way to parallel skiing through "reducing the wedge position – two ways" and "parallel edge change of both skis" [1]. The stem christie is one of the classic ways to do that – a proven methodology bridge, not an official mandatory step.

How hard is it? If you ski the wedge turn securely, first stem christies are possible in one or two sessions. How fast you get smooth depends on the terrain – there is no study on that.

What you need

Secure wedge turns. You ski several wedge turns in a row without clinging on (see the wedge-turn guide).
Blue run, wide, little traffic. The terrain should give you time.
Thigh strength. Even in the wedge, activity of vastus medialis, vastus lateralis, biceps femoris, glutes and adductors was above 50% of maximum in an EMG study [3] – so you work, even if it is "just" a wedge.
Helmet. Always.

Step by step

1. Wedge turn as a base

Ski two or three clean wedge turns. Let the skis get softer and the wedge smaller. Milestone: you ski five wedge turns with a shrinking wedge.

2. Stem the uphill ski

From the traverse you stem the uphill ski out sideways: the tail goes out, the tip stays near the tip of the downhill ski. The uphill ski becomes the later outer ski.

3. Shift weight

Shift your weight onto the stemmed ski. The hips follow toward the curve, the upper body stays calm. That is the moment the turn is created.

4. Bring the inside ski parallel

Pull the inside ski up parallel as soon as the turn is running. You ski the rest of the curve almost parallel. Milestone: the inside ski is parallel at the latest in the second half of the turn.

5. Make the stem smaller

Make the stem smaller with each turn until you only hint at it. Then you are at the parallel turn.

6. Both sides

Ski stem christies to the right and left. The weaker side usually needs more concentration.

Common mistakes

Stemming too wide. The stem becomes a wedge relapse and the turn is no longer fluid.
Weight stays on the downhill ski. Then there is no turn, only skidding.
Inside ski stays behind. It hangs like a straggler in the wedge and may cross.
Upper body turns along. You rotate the shoulders into the curve and lose the edge.

Fix: keep the stem small, weight clearly on the stemmed ski, quiet upper body.

Safety notes

The wedge is not "harmless". In the video analysis of ACL tears in the World Cup (20 cases), alongside the main mechanism there was a pattern the authors called "dynamic snowplow": the skier lost pressure, the inside edge of the outer ski caught and forced the knee inward (three cases) [2] (TRANSFER to recreational skiers). For you: do not confuse stemming with forcefully shoving the ski out – build pressure softly.
Wedge models are no free pass. A model of wedge turns names angle of attack, edge angle and loading of the skis as control variables [4] – exactly what you steer consciously.
Look before starting. Before re-entering or starting you look up and down the slope [5].
This guide explains and motivates but does not replace a ski lesson with an instructor.

Pro tip

Stem the ski you need as the next outer ski. Think of the goal when initiating – "I go onto the outer ski". Whoever only thinks about stemming stays stuck in stemming.

A practice plan for one session (practice, no study evidence):

Round 1 – stem standing: Standing, stem the uphill ski out and back until the movement is loose.
Round 2 – traverse with stem: Ski a traverse and stem lightly at the end without turning.
Round 3 – one turn: Make exactly one stem christie and then run out calmly. Quality before quantity.
Round 4 – series: Link three stem christies, making the stem a bit smaller in each.

The goal is that at the end you barely stem anymore – then you are skiing parallel.

FAQ

What is a stem christie?

A turn in which you stem one ski out, shift weight onto it and then bring the other ski parallel. It is the intermediate step between wedge turn and parallel turn.

How do I learn the stem christie?

First ski secure wedge turns, then stem the uphill ski out in the traverse, shift weight onto it and bring the inside ski up. Make the stem smaller with every turn [1].

Do I need the stem christie at all?

Not necessarily. The way to parallel skiing can also lead through reducing the wedge position [1]. The stem christie is a proven bridge, but not a must.

Why does my inside ski catch?

Usually weight still hangs on the downhill ski or the inside ski comes too late. Shift weight earlier onto the stemmed ski and actively pull the inside ski parallel.

Key Takeaways

Stem christie = stem the uphill ski, shift weight, bring the inside ski parallel – a bridge from wedge to parallel turn.
The DSLV leads to parallel skiing by reducing the wedge position; the stem christie is one option, not a mandatory step [1].
Build pressure softly: the "dynamic snowplow" pattern injured knees in the World Cup through suddenly catching inside edges [2].
