2nd in the "Skiing System Comparison". Transitions.

           The Transition comes from a great Release! 

For many skiers, this is where the trouble begins the way the release is structured. However, when the transition is approached with "certain movements", success and balance are achieved. Here again, we will compare between a PSIA Demo Team skier and a PMTS demonstrator.

(below photo The PMTS skier flexes and retracts the stance leg, and while doing so lifts the ski tip to free the leg and ski from the snow. This allows a transition movement.  This movement also changes the balance from the previous outside ski on the big toe edge to the new stance ski on the little toe edge. Now the free ski can begin tipping before the new stance ski. This creates a transition with parallel skis and parallel leg shafts.

Here is the result of this transition, a balanced stance on the new outside ski and a transition where the little toe edge is tipping and the big toe edge ski is already engaged, high in the arc and before the falline.

In contrast, we see the PSIA method where the uphill ski is flat and the tail of the ski is pushed uphill as in a Wedge Christie. Also, there is no energy from the previous stance ski to help transition or releasing due to the squaring of the hips. There is no evident balance transfer to the new ski from these movements. The skier is virtually stuck between his skis.

In the next frame below, we see the big toe edge engagement at the top of the arc, and no angles with the body going to the downhill side of both skis. Notice the knees are together and feet apart, demonstrating no balance is created for the new turn on the new ski, yet. There is also no little toe edge tipping to establish angles at the top of the arc.

This methodology is a result of the leg steering principles held so dearly by the PSIA system.
 In contrast, the PMTS System uses no leg steering, instead preferring to get the skis on an angle by tipping the feet and counteracting the hips and using the arms, hands, and torso as the external cues for this to be accomplished.

In the photo below (PMTS System) it's obvious what the two different systems produce. These are not happenstance or anomalies, the photos you see here in comparison are based on movement differences taught by two separate and totally different teaching systems. 
Below we see the PMTS method with the free foot tipping toward the new little toe edge, before either ski changes direction.

The result here is very obvious,  early angles, balance and both skis parallel on their
 new edges for the arc.

When you get the hang of PMTS there is no stopping you. (below photo) These are the movements used by world cup skiers. Notice that below is a complete edge and body change from one side to the other,  without a direction change of the skis, that is an expert skier using the best movements.

Differences in ski technique between PSIA and PMTS!

PMTS Skiing

In the below photo, the Essentials of PMTS skiing are obvious. Hip and upper body counteracting are set to the same degree. The inside arm and shoulder continue to counteract. This means they move forward and stay high (level) to keep strong counterbalance. The inside leg flexes and tips to the angles desired, while the outside leg is skeletally strong and stacked with the hip.

The differences aren't subtle and they originate from the approach to skiing and therefore the differences in the photo body position.

                                                                       PSIA Sking
Here a PSIA Demo Team skier shows a totally different approach and body alignment. The upper body shoulders and arms are in conflict with the hip. The shoulders are rotating and the inside arm is dropping and back. The hip is dumping inside. The outside knee is driven hard toward the inside leg. This is very weak skeletally alignment wise and will eventually wear on the knees. The difference in head position tells the complete story between the two skiers. The PMTS skier's head is lined up with the counteracting body, while the PSIA skier's head is turning with the body, creating part of the rotating result and also following the body rotation.

This skier also shows an extreme "A Frame" on the left knee, which is a weak alignment.

Quick Tip! Upper body relative to flexing to release. Or Check Point "No Swing pole tap!

One of my athletes holding his counter-acting.
PMTS Counter-acting is a function of the hips and upper body. The poles and arms are clear indicators as to how well it's done or how easy it is to lose counter-acting.

In this case, the practice of pole and hand use is helping the skier to prepare for a perfect release. Also, notice how the inside foot is back, this makes the transition to the new stance ski easy and quick. If you read my previous article it explains how the transition is created.

In both photos the inisde hand and ski pole tips are forward and ahead of the inisde ski boot. The ski pole on the lower side is prepared for a pole tap.  You want to think of the outside leg flexing or bending moving toward your chest whcih should be facing the outisde ski boot.

The transition of PMTS Skiing, or "how to make snow go uphill!"

Angles at the Apex of the arc.

The angles of the skis increase through tipping and bending of the inside leg. The upper body's roll is to counter-act the rotation created by strong edge angles, and quick sharp turn radi.

The outside leg has already begun to flex or bend to increase lower body angles, while the upper body come back to the falline.

Now the transitions begins in earnest as the outside leg retracts and the upper body moves toward the falline.

The knees are sucked up to the chest and the skis come flat to the snow.

The momentum of the releasing movements and gravity combine to make the edge change. The feet and legs relax to allow for this movement. The feet and legs still aid in the process managing the speed of the transition.

Tipping to the new angles with the legs requires that the upper body stays as verticle as possible helping with counter balance. 
 Balance is establsihed on the outside ski, increased angles of the skis is facilitated by inisde leg flexing and foot pull back.

 The focus should be on the inside foot, and the inisde leg bending. The outside leg followes the tipping of the inisde foot and ski.

The topics that are not covered in this post are still extensive and they are just as important as the retraction and tipping movements that are described. The actions with the upper body for counter acting and pole management are all there. As a teaser notice that the inisde pole never lags behind the boots.  Upper body and pole manaement is a topic for another post and article.
