There’s a flashlight in my belly button
Could you clarify one thing about the flashlight for me.
What I do not grasp so far is what the “flashlight – turning of the hips” does.
Judging from you remarks on skiing you know a thing or two about that as well. Being an enthusiastic skier myself, I have compared the position of carving a turn on skis with that on the bike. The only thing which seems to be different is the turning of the hips. As you surely know, during a turn on skis you try to keep your downward-pointing shoulder and hip back, so that you can keep the skis on their edges. So rotating the hips forward during a turn isn’t good on skis — why is it on the bike?
Or did I misunderstand something here?
Thanx a lot.
This is a good, smart question. I remember you posting it a while back and me red-flagging it to answer later, then I did some research … and it got forgotten. 100,000 emails a day, you know?
I like to think I know a few things about skiing. When I moved to Colorado with my ex wife, I dedicated myself to learning the art, science and kung fu of skiing. I found Ron LeMaster, a big-time skiing expert who lived down the street from me. He’s written lots of books. He lectures. He knows a few things. I guess he’s the Lee McCormack of skiing (or, more likely, I’m the Ron LeMaster of bikes)
His books are rad, as are his photo sequences shot at World Cup races. I don’t think he’ll mind if I post some from www.ronlemaster.com.

1) Cornering on skis and bikes is extremely similar. A great skier can rip on bikes, once she relaxes. And vice versa.
2) Both are quite complex, and there are different schools of thought. Skiing is a more developed line of study, and you should see how dogmatic ski “experts” can be. I attended a lecture by Ron LeMaster at the Boulder Center for Sports Medicine about ski cornering, and — wow — people were openly disagreeing with him. He’s a lot more mature than I am, and his take was, “I’m not claiming to know anything. Here are pictures of the world’s best ski racers; let’s look at them and talk about what they are doing.” Pretty great.
3) The purpose of the flashlight in your belly button (on a bike) is to orient your hips through the turn, toward the next turn. This has lots of benefits including:
• Points your upper body (and head) where you’re going. The sooner you’re oriented toward the next turn, the sooner you can release this turn to your peripheral vision and the guidance centers of your brain.
• Adds energy to your turn. Imagine carving a turn on snow or water.
• Increases the clearance for you to lean your bike. Especially with a high seat.
Note: I got the “flashlight in my belly button” idea from a ski instructor — Chuck Martin at www.mogullogic.com.
Look at my butt. Feel its power! This photo makes me feel self conscious, but it shows the hip turn pretty clearly.
4) At the high level, when carving certain types of turns, ski racers are keeping their downhill hip back for, I think, two reasons:
• Keeps the inside ski in the lead.
• Allows greater angulation of the leg and ski. Greater angulation means tighter turns.

Looking at the last image in this photo sequence, the hips aren’t exactly pointing back. They’re just not driving all the way through the turn the way they would on a bike. We’re talking about a subtle difference.
4) For most skiers in most situations, I think you can turn skis the way you turn a bike. Hip and torso driving where you want to go.
I am no Ron LeMaster, and I know I’m asking to hear from the ski experts, but this makes sense to me. Thoughts?
Bummed: I haven’t skied in a few years. No time.
Know more. Have more fun!

I think the extra clearance point is a huge one that could be easy to overlook! Really easy to validate in the nearest parking lot too. Go see how far you can drop the bars without turning your hips and then try it again with the hips turned. Sold.
I’m gonna try that. Important point for me as I don’t have an adjustable seatpost yet and I don’t lower the seat a lot when on an XC ride.
I’m impressed how you keep track of all the mails. Even more impressed how much thought you put into things which aren’t biking 😉
So, thanks for the explanations. I get what happens with your hips on a bike.
As for skiing – you should try to fit it into your winter schedule once again.(But yeah, I know myself: job, wife, kids, etc.; or as I once read on a toilet wall: “Life is what happens when you’re busy making other plans”)
And if you’re interested in how exactly the hips influence your turn on skis:
The biomechanical explanation is rather complex, so just try this. Next time you are on a rather steep slope, find a quiet spot and just STAND sideways. To prevent yourself from sliding downward you will push both of your knees to the hill -> angulation. Then try what happens to your skis when you turn the downward pointing hip forward. Angulation will decrease until you start sliding.
This effect is even stronger when you rotate your downward pointing shoulder forward (here we call that “overrotating”, which should be avoided – at least if you wanna carve).
Have fun trying!
Lee, do you “point the flashlight” ahead of when you want to turn? I sometimes feel like I turn ahead of the bike and the steering follows the correct path. I just wonder if this is wrong, or it I won’t have the correct traction when I need it if I initiate the turns ahead of the bars?
I think about, and teach, turning the hips as you initiate the turn.
The reason a skier turns his or her hips toward the outside of the turn is to align the quadraceps and butt muscles of the outside leg with the force on the skier’s body (the combination of gravity and centrifugal force, which gets up to 3Gs in giant slalom). These are the biggest, strongest muscles in the body, and are also the ones that control the skier’s overall flexion and extension as he moves through variations in terrain.
Interesting to note 3Gs is also about the max a cyclist hits: usually in a steep berm on a slalom course or pump track.
Thanks Lee and Ron,
This site is a real learning platform!
Side note: Lee, I use your cornering tips on my road bike, too, and it works great!
Ralf, sweet! Yeah man, it’s amazing what a road bike can do.
