Let's make no bones about it: the headlining sport in the Winter Olympics is figure skating. No other sport comes close to the drama, the athletes, the subplots, and politics that figure skating has. For skaters, all those hours, jumps and training are boiled down to around six or seven minutes. That's what makes the Olympics' skating competition so wonderful and so heartbreaking: skaters don't necessarily have to be the best, they just have to be the best for seven minutes (see: Lipinski, Tara). 

That's why we watch. For most of us though, the benchmark of a good skate is not falling (part of the reason people were surprised that Mirai Nagasu didn't make the Olympic team despite skating a clean program). To the untrained eye, a skater just transforms into a spinning blur for a few nanoseconds, and then lands (or doesn't) while we hold our breath. 

With the power of GIFs, we can now go beyond that to actually see these jumps — what makes the Axel so treacherous or the Lutz so difficult. And we can also tell these jumps apart.  

The Wire talked to former U.S. Figure Skating National Team member Katrina Hacker to help us explain jumps in plain English. Here's what we learned:

The Basics: 

The six most common jumps in competitive figure skating can be divided into two categories: toe jumps — the toe loop, the flip, and the Lutz — and edge jumps — the Salchow, loop, and the Axel. The cool names like Salchow, Lutz, and Axel came from the skaters who invented them. 

"In toe jumps, the skater plants the toe-pick of his free leg and uses it to help launch him into the air. In edge jumps, the skater essentially just uses knee bend to launch," Hacker told The Wire. 

The takeaway here is that you can start to tell the jumps apart by looking how the skater is taking off. Are they using a pick or an edge? By determining what they're doing (using the toe-pick vs. the knee bend), you can use the process of elimination to narrow down the kind of jump it might be to three. 

Further, the Axel is the only jump that begins with a forward approach. If someone is facing the jump head-on, you're watching the Axel. 

Edges?

The toe-pick is pretty easy to explain (easier if you've ever watched The Cutting Edge). You'll see a skater kick the front of their blade into the ice before a toe jump. "Edges" are a bit more difficult to comprehend for a person who's never figure skated before.  Thankfully, Hacker has skated before and can explain. 

"The skating blade has a hollow and therefore two edges: the inside edge and the outside edge. If you stand with your feet parallel, the inside edges are on the inside facing each other, and the outside edges are on the outside," Hacker said.  "A skater uses these edges for everything — the edges are essentially what give the blade traction with the ice," she said explaining that skaters are constantly switching between edges throughout a routine. Shifting between edges is as simple as taking a tiny lean or a bit of pressure to the outside or inside of your foot. 

The Jumps

So, right, there are two types of jumps. And we have some idea of what an edge is so we can tell them apart. The final component to the jumps and what differentiates a Salchow from a loop is the take off and landing. All jumps end with a skater landing on a back outside edge (in skating right-handed skaters usually land on their right foot, jump and spin counter-clockwise, while left-handed skaters land on their left and so on). What sets these jumps apart from one another is how they start. 

Here are the six jumps in ascending order of difficulty the points they are worth in competition (we hesitate in saying difficulty because some skaters might have an easier time with one type of jump versus another):  

The Toe Loop

This toe-pick assisted jump starts from the back outside edge and lands on the back outside edge of the same foot (if you're right handed, this is taking off from the right foot and landing your right foot). The toe loop above belongs to Russian skater Maxim Kovtun.

Salchow

If you look at the Salchow that Shizuka Arakawa is performing and scroll up to see Kovtun, you can see the massive difference between an edge jump and a toe jump. The Salchow starts from the back inside edge (if you were standing straight up, the edges that face each other) and lands on the back outside edge of the opposite foot (if you were right-handed, you'd take off from your left and land on your right).

The Loop

The loop is another edge jump, where the jumper (in this case, Johnny Weir) takes off from his back outside edge and lands on the back outside edge of the same leg. An easy way to remember this jump is that it's basically a toe loop without the assist of the toe pick. 

The Flip

The flip like the toe-loop, is a pick-assisted jump. The difference between the flip, the toe-loop, and the Lutz is that the take off begins from the back inside edge and is landed with the opposite foot. 

The Lutz

The only difference between a Lutz and a flip is the edge the skater is taking off from. Some skaters "cheat" and take off from the wrong edge when attempting to do  a Lutz, which calls for takeoff from the back outside edge and landing on the opposite foot. What also makes the Lutz difficult is that it's counter-rotated, meaning that the rotation of the jump is the opposite of its entry.  The triple Lutz above belongs to 2010 olympic gold medalist Kim Yu-Na, whose strongest jump is her textbook Lutz. 

Here's a better look at Gracie Gold taking off from her outside edge.

The Axel

The Axel is the easiest jump to tell apart from the other because of its entry — it looks particularly cool because the skater is taking this jump head-on. The Axel is also the hardest jump. Here's a slow-mo version of Mao Asada, one of the few women in history who has landed the triple Axel and one of the only women who regularly attempts it: 

What you'll notice is that the jump is actually three-and-a-half rotations. "The axel is a particularly treacherous jump because it's the only one with a forward takeoff, which adds an extra half turn to the jump," Hacker said. That makes it more difficult, and worth more points. What you'll also notice in this replay are Asada's feet— she's taking off with her forward outside edge and landing on the opposite foot. 


The Points

If the only thing separating one jump from another is the edge and switching edges can be as simple as applying pressure,  then it becomes relatively simple to "flutz" (take off with the wrong edge) a Lutz. And with all these different moving parts, edges, legs, landings, revolutions, etc., judges have the tough task of being meticulous with grading. That's why the International Skating Union now has a technical panel which uses instant replay to make sure feet are in the right position and the correct edges are being used. 

But just meeting the bare minimum isn't the ultimate goal here. In skating, you get bonus for points for jumping beautifully — beautiful means getting major height, covering a lot of ice,  going into jumps with the speed of a freight train, and technique/form (see: Kim's triple lutz). That's reflected in the Grade of Execution score, where you can be deducted or gain bonus points depending on how well you do a jump. 

The Ultimate Goal 

In order to score the highest amount of points, it's been established that you have to skate beautifully. But landing quad after quad or triple after triple isn't enough. The only thing better than landing on beautiful jump is landing two beautiful jumps and the only thing better than landing two beautiful difficult jumps is landing two beautiful difficult jumps in a row.

Performing a jump after just completing another is what's known as a combination. And combinations, because of their difficulty, are worth a ton of points. There's a lot that goes into one jump, and doing another in rapid-fire succession brings in so many different elements, and so many things that could go wrong. Here's what happened to Ashley Wagner, the top US women's figure skater, at Nationals when she didn't land her first jump the way it was supposed to:

That's why you'll usually see a tough jump like a triple Lutz or triple Axel followed by an easier jump. Some men's skaters are capable of incorporating a quad jump followed by a triple. The goal is here to a) land the combination b) land the combination beautifully like Kim does here: 

Now you are now ready to go wow your colleagues and friends with your knowledge of the Salchow and the Lutz. You get bonus points if you refer to a jump as "treacherous," as analyst and skater Dick Button would say. The team skating competition (a new event) begins on Thursday, the men's competition begins on February 13, and the women's competition starts on February 19.
