It's exciting when you see someone jump, turn in the air, and land. You can't do it overnight. It takes time. It also takes precautions. At DiGregorio's rink at the University of Delaware, all skaters, regardless of their level and skill, wear pads when they practice.
Pairs skaters wear helmets.
They do 40 minutes of off-ice conditioning and stretching every day, as well as 40 minutes of dance work. But I don't believe in that all year round. Some skaters seem to be getting away from that, though. That's only true in theory. There has to be a point at which they do enough with the individual jumps to be consistent and comfortable, but not so much as to damage the body.
