Welcome @matias-delsolar and thanks for posting!

With the exception of that first toeside (0:14) the rest of the toesides are pretty good.  The first turn is always the hardest, before you have a rhythm going.  At that first one you're breaking at the hips and leaning the upper body towards the snow.

But your question was about the heelsides, so let's look at those, the ones from 0:40 onward.

Rider is at 27/12, 57cm stance on an Arbor Padre 161 (7.5m SCR, 123.6cm EE).  184cm tall, 85kg.

So you're making the classic mistakes that everybody makes: your hips are facing the toe edge in the heelside turn, and your back knee is pointing out across that edge too far towards the tail.  Your back hand hovers over your tail end of your toeside side edge, and that's a classic indicator of these mistakes.

To fix this, you'll want to focus on both the back knee and the hips.  Drive the back knee forward, right into the front knee like a longboarder (or like Terry Kidwell in the photo below).  Drive with the hips into the turn so that they're twisting towards the nose of the board.  These motions go together, so that when you twist your hips toward the nose the knee will have to follow.

Another way to practice this motion is with the Hand-To-Knee drill.  Touch your front knee with your back hand on heelside.  But...  when you do this, make an effort to bring your hand there by twisting the pelvis rather than by reaching the arm across your body.  If your bicep is touching your pectoral muscle, you're reaching across your body...

Look at this screenshot for example.  My back hand is naturally hovering right over my front knee yet my upper arm extends from my shoulder in a relaxed, neutral position.  It's not reaching across my chest, it's brought to the front knee by rotating the pelvis.

Contrast this with this other screenshot of Mr. C:

See how he's facing the toe edge and reaching the back arm across his body to touch the front knee?  Avoid this position, we call it "The Toilet" position; his butt is sticking out behind him and he's not driving with the hips.  His back knee is pointing over the toe edge, a little behind him.  He doesn't have a lot of control over his board in this position, he has to just balance there are hope to maintain the edge.  (Mr. C is on a Coiler Contra 169 x 290mm waist with full Titanal construction and a 12m sidecut radius, so he can get away with this position on green runs whereas the Arbor will be far less forgiving.)

Hope that helps!  Try this and post another video tomorrow!

Hola James.
I put into practice your advice. Trying to rotate more the hips and bend the back knee forward. Still struggling trying to absorb the bumps on this new position, also if I heel more the board my back binding will touch the snow and lose the grip… attached some new pics and videos, this time I tried with a board a bit wider and stiffer than the Padre, it is a Coda 164.

about the back had I followed the advise als well and tried to keep it holding a cup and level with the other one.

much appreciated your advice!

Hi Matias!

This second video seems to me much better in terms of hip rotating at heelside, still seems a little bit the toilet position but, from my point of view, there is an improvement. Keep practicing.

One thing is working for me is repeating mentaly, before each turn, this phrase: "hip rotation, look forward, shoulders level" in an effort to simplify the theory.

If you fell you have a lack of confidence or you are a little bit scared of trying to lean your butt to the snow i´ll recomend you to follow the drills explained in this video:

Both english or spanish subtittles are allowed. Asian technique is quite different from what James uses to explain but the base is almost the same, hip rotation and shoulders level, and if you are looking for different exercises to practice, it is working for me...

Regards!

Hello again @matias-delsolar.

This second video is much better!  Looks like solid progress to me.   Slush is tough man.  We can't dig into it and carve trenched like cold corduroy, it's more like building a bank to ride on at the same time you're riding that bank...

Your back knee is still pointing out though and your hips need to drive further into the heelside arc.

As it happens, I just published the second part of the "Just the Tip" series and it's probably exactly what you need to see:
