Downhill ski:
Stay between the two gray lines, for no gate faults easily.
Ski jump:
On the ski jumping event on either the normal or large hill, if the circle on the arch strays to either the left or the right of the center, move it to the opposite side of the center to counter-balance yourself. This will take effect when you take off. If done correctly, you should find that before when you tilted to the side that your circle did, you will now stay level and will achieve a much further distance
