CHALLENGE: Leaning back
A modern ski's sweet spot, like the optimal hitting point on a tennis racquet or golf club, is large compared to older models. The sweet spot is under your binding, between your arch and heel, where the ski is most narrow. If you move your weight outside that area, your ski starts to act up: Lean too far forward and it wants to overturn; lean too far back and it wants to run straight. Undisciplined movements also interfere with good balance.
