发帖数: 669 | 1 Day 2 (theme: counterbalance)
Jay and Andrei showed up shortly after 6:45pm. Yesterday Andrei had a Head
Supershape ski, today he came with a Head Icon TT 80 ski. As it turned out,
he would have a different ski every day of the camp –Movement Jam on day 3
and Head iPeak on day 4. All are Harald Harb recommended skis. Rich guy.
The theme of the day was counterbalance (CB). When you tip skis to one
direction (for example left), you move your upper body to the other
directory (right) to counter the lower body movement to maintain balance (
solidly on the BTE of stance leg after the transition till the end of the
turn).
Jay explained to us that there are four body parts involved in CB – arms,
shoulders, torso and hips, in the order of the difficulty and effectiveness
of the movement. Arm movement is the easiest but least effective, while hip
movement is the most difficult but most effective.
Drill #1: Double pole drag. (This is actually a flex drill but Jay asked us
to do it to warm up.) Arm outward and forward at 45 degree and at chest pack
height, poles flaring out at 45 degree. Hand knuckles facing forward. Pole
tips closer to tips of the skis than toe pieces of bindings. Ski with both
pole tips firmly on snow. The emphasis is to avoid upward leg extension to
cause the pole tips to leave the surface of the snow.
Drill #2: Same as #1 but press downward and outward of the pole tip on the
stance side. Use upper body to press by tilting the stance side shoulder/hip
downward and contracting the stance side rib cage. Do not press the pole by
just using the stance side arm. Switch sides during turn transition.
Drill #3: Same as #2, but move back the stance side pole tip level with heel
of boots and move forward the other pole tip level to the ski tip. This
adds counter action (CA) which would be covered in much more detail on day 3.
Drill #4: Same as #3, but no longer drag the inside pole tip. Raise it
forward and high at ear level. Tilt the inside shoulder/hip upward and
expand the inside rib cage. Full CB now.
Drill #5: Boot/knee touch. Same as #4, except that instead of dragging the
stance side pole tip on snow, touch the stance side boot or knee.
Drill #6: Carry both poles horizontally and laterally on the shoulders and
behind the neck, with each hand holding one end of the poles. Tilt shoulders/
hips and contract or expand rib cage so that the poles point to snow on the
stance side and to the sky on the other side.
Drill #7: Hip-O-Meter. Two poles looped around the hip. Tilt or lift hip so
that the poles point downward on the stance side and upward on the other
side.
Jay then explained that for shoulder, we could think of shoulder girth as a
bowl holding water. When we tilt it, we could visualize pouring water out of
the bowl. Same could be said of hip as well if we could think of the pelvis
as a bowl. We could also think of the hip movement as lifting the inside
hip socket (this is what Harald Harb thinks), or pressing the stance side
hip socket diagonally down to the inside ski (this is what Jay himself
thinks), or rotating around a fictitious pin inserted into the middle of the
pelvis from front to back (this is what Diana Rodgers thinks).
Sometime during the middle of day, Jay told me that compared with day 1, my
turns were more rounded and had much better speed control. He asked me what
happened. I told him that I thought it’s because of the better timing of
the flex prior to release. One day 1, my flex move was way too early, so my
stance ski did not hold its edge well during the lower half of the turn, as
flexing stance leg tends to flatten the ski. As a result, my turn was less
round and gained more vertical drop, making it going faster. Secondly,
because I was so low at transition, I had to extend right after transition.
This caused some skidding during the top half of the turn, making the turn
less round and ski go faster. Jay agreed.
The drills today revealed some more problems in my skiing.
Problem #1: Inconsistent and week CB. On most of the turns, I think of
lifting the inside hip socket but I don’t have much torso and shoulder CB
movement. I hardly think about it. Also, I lift the inside hip socket as a
way to lift or lighten the inside ski to tip, it’s good enough for tipping
the inside ski but it’s quite weak as far as CB is concerned. Moreover, CB
is gone when I flex to release. This is fine but the timing of my flex is
off so CB is off too early.
Problem #2: Hands too close, arm dropping, hand knuckles facing down (
suitcase position). Jay pointed it out on day 1 but it’s more visible today
during the double pole drag drill.
For the problems we found one day 1, there was an obvious improvement in the
timing of my flex, but the little extension after transition was still
there in some of the turns, as the video showed. My transition still took
too long. Jay said this is my most visible problem but it will take me a
while a fix. | B*N
