Review the classic stride.
Review the double pole.
Try
using a static position with 2 students facing one another. 2 hands in
the air, elbows bent, and one of the skis held back behind them. They
need to have an understanding of what the position will feel like in the
first glide position.
The mantra is kick, glide, pole, glide. Many people do just kick, pole, glide which is incorrect.
They should be able to count 1,2,3 in that first glide phase. Use imagery like a conductor directing an orchestra.
Have
them go down a slight incline or on the flat with no poles doing the
single kick double pole. The whipping upwards of their hands will move
them forwards.
They can also imagine hugging a tree for the forward position, i.e. elbows out and hands shoulder width apart.
In that first glide phase, you float and glide before doing the double pole.
Be
aware that you are always leading with the belly button. There should
be no curvature in the lower back (do not be upright), but be leaning
slightly forwards from the ankles as you initiate your poling, and fall
on your poles using gravity, core, body weight in each cycle.
Anytime
you are gliding the weight is too the heels, pulling up on the toes.
Always remember that the angle at the ankle, constantly changes,
depending on where you are in the cycle, from center of gravity, behind
the ankle, over the ankle, and then ahead of the ankle. The actual power
of the poling action occurs just as you are falling forwards. This also
will keep the feet warmer.
-Alternate the single kick phase using one leg, then the other to kick with, do not favor one leg.
Practice
doing a high tuck, poles tucked in against the body, every few single
kick double poles, and try to reduce the number of poling actions that
you need to take, especially when it is windy.
Practice doing synchronized single kick double poling too, in a train, just like double poling.
Remember
that the leg and foot that is going to kick, slips slightly ahead,
about a foot or so, to allow more time to allow the wax to grip, for a
kick.
When
they have mastered single kick double pole without poles. you can then
add the poles for real. Never add more to a movement, until the student
has mastered the basics. Add one body part at a time till they have it.
Many students are weak on one side or the other, so watch and be aware of this, and try to correct the weak side.
A leg coming down too soon, or an arm flailing outwards or inwards, will be a quick indication of correction needed.
When to use the single kick double pole is usually determined by many
factors. Your strength, speed of your skis, type of snow conditions and
the track conditions are just a few suggestions. Single kick double pole
should almost always be used as a gear between double poling and
diagonal both as you speed up or are slowing down.
