For sure.

A good analogue is “perceived rate of exertion”. It’s almost meaningless in sport.

When I ski on some days, my PRE is high. But this may not reflect my heart rate (which says exactly how hard I’m working). On great days, I feel low PRE but am operating at Zone 5+. Everything is clicking… or it seems to be until I look at my speed and splits, which might be dismal.

When feeling, performance, and measurement aligns, you know the past few weeks of training or practice are having an effect. But you’d never “get there” without applying exercise science.

You make skiing sound so fun. You must be a blast to ski with.

Going fast is fun, exceeding expectations is fun, carving a turn is fun, racing through a difficult section is fun, braving the elements is fun.

Getting there requires preparation and practice. If you skip that, you’ll never experience how much fun you can actually have. Life will be a series of yard sales and lost opportunities.

Thanks for taking the time to do some very welcomed life coaching! Without your gentle but firm and obviously welcomed teachings, I may have never seen the light. Thank christ for you internet skier, thank christ.

It wasn’t meant for you. Not everything is.

I just wrote how I manage to have fun. IDK why this seems to trigger you, but it does.

Maybe it would be better if I alternated between cat videos, photos of mountains, and endless debating on what Asnes ski will take my modest abilities to a transcendent level?

Thanks for the old style binding video. I had a pair of 1957 head skis, with the old cable bindings, That I found in a Vermont barn. They were embossed with the name of a previous olympic skier. I used them for lift serve at Mad River in Vermont (with my Extreme leather boots) both with the cables hooked under the clips and without. It was much easier to ski those heavy boards on crust and hardpack with the cables hooked down, and my heels “fixed” to the ski, as would be expected. I stopped doing that after a twisting fall, the skis could not release, and some pain in the knee resulted.
I still think the primary aid to skiing from cables or active bindings is the additional lateral heel support. However, I find that is offset by the restriction to “going low” where dropping my center of gravity (in a way fixed heel skiers cannot), promotes better control.
See attached photo (please disregard my “flailing” arms held out for balance and to prevent knuckle dragging).

That’s cool you had one of those old bindings working. I’ve only seen broken ones nailed to walls on chunky old all wood skis. Very cool though. I heard they could be used for either tele or alpine turns. It looks like the back cable hook is for alpine skiing, maybe too “active” for good telemarking. Yeah, could cause injury especially if your boots uppers aren’t soft. I was surprised to see that the “relief hitch” mode for climbing, with the back cable hooks undone was still quite stiff in the forward flex due to the still rearward pivot, probably better for tele turns than skinning or XC. That reminds me, the original 3 pin inventor guy I heard won a cross country race because he wasn’t fighting the resistance of the binding like the guys with the cable bindings. IIRC.

Whole thing:

Note in the photo, the tip/front of the skis are not spraying snow, the action is beneath the boot (and a foot or so forward and back).

Yes, the front of the front ski isn’t going to be pressured so much in a tele turn. The main thing is engaging the front of the rear ski, especially in certain portions of the turn, is going to help get it tracking around with the rear ski. You can also pivot and skid skis of course.

That seems to happen pretty well when going shins to ski. Unless form is way off, the thigh, glutes, and torso end up being directly over the pivot point (or even further forward).

I’m pretty sure….. if you have a free pivot at the toe, like an AT binding with the heel unhooked, you can’t pressure the tip of the ski more than the tail.

I’m going to test that in the living room with a physics apparatus.

You’re not pressuring the tip of the ski.

You’re applying body mass the front portion of the ski that makes contact with the snow. You’re even flattening the camber and pressing the pocket. All through the ball of the foot.

[lowangle al]

With the lead ski you can get more weight on the front of ski by putting more weight on your toe than your heel. Even without a cable you are getting some forward weighting (tip pressure) on your ski because you are weighting the ski forward of boot center.

So believe it or not you are getting some tip pressure on every turn with a properly weighted rear ski.
