In this instructional video, Tom Gellie expands on his previous discussion of isolated quadriceps use in skiing by presenting two dry‑land exercises designed to develop that movement pattern. He first demonstrates a wall‑supported knee‑extension drill that isolates the quads, allowing the skier to move the centre of mass forward and generate tension through the calves and ankle, which loads the forebody of the ski. He then describes an isometric side‑leg quad hold, performed with the outside leg extended laterally, to train the ability to maintain resistance while keeping hip mobility for turn initiation. Throughout, Gellie contrasts quad‑driven knee extension with hip‑glute‑driven extension, explains why moving mass forward is crucial for ski turn dynamics, and advises a training mindset that focuses on mass translation rather than the generic strength gains of squats. The video aims to give skiers concrete, biomechanically‑informed drills to improve quad isolation and edge pressure control.

This video is designed to go with the previous video on isolated quadriceps use in skiing, and I had a few people ask what would be some exercises that they could do dryland to train this movement. So I'm going to try and get that across in this video. So, what I was talking about previously was getting people aware of using their quadriceps, which extend the knee or take it from being bent to being straighter, as opposed to using hip extension and the glutes, hamstrings to extend the knee via the hip extending first. So hopefully you can get your head around that. So, if I use my quads only, I could actually extend my knee without extending my hip that much. So here is an example. So this would be the first exercise you could try with something, a wall in front of you, to feel extension from the knee not being coupled with hip extension. So that would be the first thing. Why that would perhaps be useful in a ski turn comes down to this. When I use the knee extension alone, the result is my mass only moves forward. And if I do it to the point where I don't fall over, so right here, what I start feeling is an increase in tension through my calf and my Achilles and under the soles of my feet. So I've created some leverage through moving my center of mass forward through the ankle joint, which would help me load up or apply more pressure towards the forebody, the front half of the ski. Now if I do say something different, so my extension comes from quads, knee, and glutes, I end up coming up, but I don't have the same sensation of feeling tension through my calves and under my foot because my centre of mass is essentially still over. If I keep the flexion from the previous turn and now extend, The result is now this isometric tension created through the back half of my legs from my center of mass being pitched forward. So there would be one, hopefully, explanation and a simple way of training the quadriceps for skiing. So the outcome would be tension through the calves and the ankle joint. You should feel your center of mass be moved forward, not just stayed central and moved up through hip extension as well. So that would be one, and then the second thing I would say you could work on, because that would be more a turn initiation type movement, would be an isometric contraction of the quads. With your leg out to the side, which would give you the feeling of being able to hold resistance or hold this leg long, the outside leg long, while still being able to mobilize it. So extension, mobility in the hip joint. Extension, mobility in the hip joint. So there would be two simple ways. It really comes down to actually you being aware of what you're doing and thinking about what is it I want to achieve with, with the training. Because when you do squats, you're going to be training the quadriceps, the glutes, the hamstrings, a whole bunch of stuff. But a squat, as opposed to in skiing, is just meant to take weight from down low and push it up higher. Where in skiing, we're not really trying to do that. There's more an importance on moving mass forward and back to find a really sweet spot along the ski to make it work. So there's the maybe the mindset you need to, to think about to help get your head around this. So all the quadriceps exercises you can do are great, but then when you use it in isolation, the goal is to help move some mass. Hope that helps. Thanks.
