One of the most typical mistakes you see when skiers are close to the limit of their abilities is that they get all rigid and stiff. This is a natural defensive reaction when we try to protect ourselves – or even if we try to be strong. We tighten up all our muscles. This strategy is not meant to use in the long run, though, just as a sudden reaction. Why? First of all if we are all tense, we fatigue much faster. Secondly, how are we going to mobilize strength if we are already contrated. Thirdly, when we are stiff, we are not free to absorb the bumps or other changes in terrain.
