Trusova is strong though. Those ‘ballet’ photos for Adidas show impressive abs and obliques (?).
Aleksandra has the right build, relatively tall but slender, strong legs, core, shoulders.
I don’t think she will loose her ‘spring’ required for performing clean quads even when she gains a little in her hips or bust.
She herself is determined to keep them in her repertoire, almost at all cost in training efforts.
And her success rate in landing them without too much deductions is like 80%, which seems OK to me, a risk worth taking.
The mechanics of quad jumps in girls her age should be very interesting to study in a scientific way. What power is required to get the height and how to launch properly, what speed on entry to get the rotational momentum and how legs, core, chest and shoulder muscles should cooperate, how to safely land w/o UR and to absorb the remaining inertia to skate out of the quad cleanly and at speed.
It all goes so fast, a high speed camera reel slowed down and Aleksandra in a special jumpsuit with positional and inertial sensors might be needed and many jumps of course to acquire the needed data and footage from all angles.
I would love to see a scientific documentary made about and with Trusova’s skating and jumping skills, much like the groundbreaking “What makes Milo fly” in gymnastics.

And how to train a quad? Using the ‘harness and fishing rod’ in the gym, using the ‘fat suit’ on the ice. Lots of falls probably which might not look good .... but shows how determined Aleksandra is and how dedicated her trainers are in making those elements work for her, The Quadster, the only girl in the world that drives Quads and jumps Quads ;-)
