1.
Steering for Control and Efficiency
Develop finesse in steering skills for control in different conditions.
Efficient steering means maintaining control over the speed
and direction without fatigue and wasted effort. Turning the legs
quickly and independently of the upper body provides control and
good balance on steep terrain. The skis will be on edge, but not
necessarily cutting a pure arc. Maintain balance over the middle
of the downhill ski by committing the upper body to the pole plant.
Tactics
• Reach down the hill for the pole plant.
• Hop turn, make sure the legs turn first.
• Sideslip in different parts of the turn.
• Hockey stops, edge sets.
2.
Advanced Bumps
Advanced bumps combine technical abilities and a tactical approach.
Some skiers need to consolidate their technique to become
more comfortable in the bumps. Others struggle because of
not knowing where to turn. Choosing the right line depends largely
on the shape of the bumps. Use the top of the bumps to change
direction. Redirecting the skis takes less effort if timed when only
the middle of the ski is in contact with the snow. Develop a relaxed
and supple stance to absorb shocks. Maintaining snow contact is
important for control. Avoid the troughs, especially in marginal
conditions. The troughs are often icy and rocky, and impose a
challenging and fast line. Use a rounder turn shape to steer around
the troughs and stay on the good snow. Steering into the bumps
from “10 o’clock” and “2 o’clock” offers another option for line
and speed control.
Tactics
• Round turns in the bumps to develop pressure control.
• Reaching over the bumps with the pole plant for stability.
• Edging on the back or shoulder of the bumps to avoid the
troughs.
• Hop initiation before reaching the bump to reduce impact.
• Hop with steering.
• Airplane turns.
• Retract the legs over the bump.

Advanced Competency -
Loading and deflection
Creating rhythm by using rebound and deflection is part of the
thrill of skiing. As skis grip and bend, the forces increase. The
skis and boots can act as springs, combining with the skiers own
work effort. Resisting these forces stores potential energy (“loading”).
This energy can be used to change trajectory and to increase
deflection across the slope. Directing this reaction can generate
speed.
The lower body steers while the upper body stays
stable. This stores energy.
A pole plant blocks the momentum of the
upper body and lets the legs turn in a
new direction, releasing stored energy.
