Great! I thought I had been hearing about this for a while, but added expense was always brought up as prohibitive.
ETA: I'm not sure what the sweet spot is for training high-level jumps and maintaining health. On one hand, leaping into the air and falling is never going to be risk free. Is lighter and younger and fearless, gaining the muscle memory earlier, better? Or is older with stronger skating skills and less overall potential harm to joints, etc. better? Is training jumps harder on the body than maintaining them, and if so, when is the best time to train? If not, and maintaining jumps is just as rough, again, when do you aim for having all triples consistent?
For a competition-ready double axel, I'm going with a baseline of 6 months training for a precocious skater with great coaching and pristine basics, to 2 years for athletes who are "grinders" when it comes to acquiring skills. What is the typical timeline for acquiring the lower and higher triples? Again, I've seen everything from a few months to, really, never.
