I've been working with a friend helping him practice PMTS movements. He attended a Super Blue camp in 2014 and is planning on another session in 2016. He's doing better, but at a slow pace. His blockage now is getting counterbalanced, especially during high C.
Tipping is good. Feet could be closer together, and he's working on that. (I had him working on a simultaneous 4-axis movement. Lighten the new free foot, tip it, pull it back, and pull it in to the stance boot.) Free foot management is going well. Counteracting is becoming automatic. He's relaxing to release, and that helps him eliminate his old heel thrust to start a turn. He's a good athlete at everything but skiing.
His blockage is getting past leaning in toward the hill. Getting his head and shoulders out and counterbalancing is the problem. Getting the feet really pulled back at the start of the turn. Video at the SB camp showed him getting upside down in one turn, but he had so much going on that he didn't feel it and doesn't know what he did right in order to repeat it. Getting that wonderful feeling of diving into the abyss and having your skis working under you. I've tried the two pole drag with CA. I've tried having him hold the outside pole a couple of inches off the snow way downhill from his heel. I've tried putting him into a demo position by poking him in the ribs with my finger while I pull the inside shoulder out for a traverse. He blocks it. He wants to do it, and his body (or likely his mind) won't let him.
Suggestions?
