I would hope Stephane is taking the same approach with relearning his 3Axel that Joannie took with relearning her 3Lutz. Taking it step by step and breaking the jump down by the basics. It took Joannie 2 years to make her Lutz a reliable jump. I'm not a skater, but I imagine relearning a jump consists of relearning the pattern on the ice into the jump, relearning the timing, the correct edge takeoff or where and when exactly to place the toe pick into the ice, the air position/where to position your arms into the take-off of the jump as well as when you are in the air and how tight to make your feet in the air, awareness of where you are in the air to ensure that the body line is straight and not tilted, making sure you know exactly when and how to check the jump on the landing to avoid a fall, where to breathe before and during the jump, knowing the right amplitude that works for yourself and the jump, knowing the correct/best way to fall in order to avoid serious injury, and knowing how to try and save the jump should the skater have a less than perfect air position and/or landing. Even the way a skater presents a jump requires attention to detail in terms of the speed going into and coming out of the jump, knowing the best transition going into it to earn the most points, and ensuring that the edge coming out is clean and that your arms present an effortless, rather than a labored, jump. There are so many factors involved and it can really take some time and be burdensome for the skater, but the end result is obviously worth it once the consistency is there. Skaters sometimes do have to relearn technique as they get older and their bodies change (weight management/body development). You really have to admire all the work involved to become an elite skater!!!
