Dry land workouts were a huge part of real-life Valpix's own skating development (albeit a different flavor of skating - speed skating), and you can honestly do a lot with it, which has helped Louise St. Martin throughout her career. I forget what it's called, but I used to have this thing where you could slide on it that was intended to develop your stride, and I also owned a band that I would tie to something where I would be able to lean and simulate the form used for turning. It worked well other than the time I ripped off a part of my parents' porch because I tied to something that was not ready to deal with my thiccness.....it all helped me on the ice and it's something that's borrowable.

In addition, there's also plenty of just weight work that helps. Leg presses, squats, stuff like that. It's not just top speed that's important, I'd argue acceleration is even moreso.
