Of course, it's not that Reine couldn't perform the complete set of movements.
With Reine's physical condition as a senior Great Knight, he naturally could execute the whole set of movements.
It just felt awkward, and Reine could subtly sense that this set of movements didn't enhance his body, but rather caused minor injuries.
Reine had some realization in his heart.
That must be what the Sword Bearers instructor had said before, because his body had already adapted to the initial breathing technique and had adjusted and adapted to it, basically becoming gradually set.
Changing the breathing technique suddenly would not only stall his strength for years,
but if his body didn't adapt to the new breathing technique, his strength would even decline after a few years, and his body would sustain serious damage.
However, Reine's goal was not to change his breathing technique in the first place.
