It is common to believe that to turn we must perform an extension. Our objective should be to generate pressure, not just to extend the legs. If the objective is to generate pressure, then we will utilize the extension movement. In other words, we should think about the effect we want to achieve first (pressure) and then determine which movement we will use to reach it (extension).
Pressure generation tends to produce active extension in certain cases (depression/unweighting phase) or situations where pressure is maintained through an isometric extension.
Intentional Pressure vs. Empty Movement
To help you understand the difference between effect-driven movement (extending to build pressure) and movement for the sake of movement (extending just to extend), you can use these concrete on-snow scenarios.
Scenario A: Low-Speed Turn Initiation (Green to Light Blue Terrain)
Extending Just to Extend (“The Pop-Up”)
- The Action: At the transition between turns, the skier suddenly stands straight up, completely extending both legs before the skis even finish crossing the fall line.
- The Resulting Error: Because the movement happens when there is little to no external force (G-force), the skier simply moves their Center of Mass (CM) upward into a static, high stance. Once they are up, they have no more extension left to use. As they enter the turn apex, they are forced to twist their hips to turn because the skis are unweighted.
- The Sensory Result: The skier feels a brief moment of lightness followed by a complete lack of edge grip at the turn apex.
Extending to Build Pressure (“The Progressive Push”)
- The Action: The skier initiates the turn by subtly changing edges, and then gradually pushes their outside foot down and away from their body as the skis head down the fall line.
- The Resulting Success: The extension is timed perfectly with the build-up of speed. By lengthening the outside leg smoothly, the skier actively resists gravity, forcing the outside ski’s edge to bite into the snow pack. The extension matches the exact amount of force needed to bend the ski.
- The Sensory Result: The skier feels a heavy, building sensation under the arch of their outside foot, and the ski cleanly carves without slipping.
Scenario B: High-Speed Linked Carving (Advanced Blue to Black Terrain)
Extending Just to Extend (“The Leg Lock”)
- The Action: Eager to get high edge angles, the skier violently snaps their outside leg into a fully straight position right at the start of the turn, locking the knee.
- The Resulting Error: By locking the joint instantly, the skier breaks the kinetic chain. The fully extended leg acts like a rigid stick. When the ski hits micro-bumps or changes in snow density, the bone-to-bone lock cannot handle the sudden spikes in Ground Reaction Force. The ski chatters violently across the snow because the leg has zero room left to modulate pressure.
- The Sensory Result: The skier feels jarring vibrations shoot up their leg, their thigh muscles tense up in a panic, and the outside ski skips wildly outward.
Extending to Build Pressure (“The Elastic Pillar”)
- The Action: The skier targets a specific amount of pressure needed to hold the high-speed line. They extend the outside leg toward the snow, but stop just short of locking the knee, leaving a small, athletic bend in the joint.
- The Resulting Success: The extension is treated as a tool to feed the ski into the snow. Because the knee joint is not completely locked, it preserves the ability to perform isometric or auxotonic contractions. The leg maintains an optimal load vector while remaining dynamic enough to adapt to the terrain.
- The Sensory Result: The skier feels an immense, stable G-force pulling them through the arc, combined with a smooth, continuous slice sound against the hardpack.
Summary Table for Self-Coaching
Use this contrast to correct your focus:
| What You Feel | Your Misconception | The Correction | Actionable Cue |
| The “Jack-in-the-Box” (Sudden, early vertical extension) | “I need to stand up to start the next turn.” | Extend into the snow to build pressure, not away from it. | “Don’t stand up. Push your outside foot away from your hip to feel the edge bite.” |
| The Locked Knee (Rigid leg, chattering outside ski) | “A straight leg means maximum power on the edge.” | Extension must leave a buffer zone to manage pressure spikes. | “Keep a pocket of air behind your knee. Use your leg like a strong car shock absorber, not a wooden post.” |
