Today's article may provide some clues. My materials and coaching techniques are very popular in Europe, Asia and South America. I have also met several Canadian coaches who are very familiar with my techniques, including the very famous Louis Cayer.
USA coaches, minus a handful, have resisted to drop the old style. They mix it with the new, and that does not work well either.
It's not that I am inventing something new. I just applied sicence and observation to a field that had been full of misconceptions complicating a beatiful sport. Through my work, gone are those complications which prevent a player from achieving their very best.
Avail yourself of all of it and I promise you you'll be very happy with your own game.
