Here is a link to the videos demonstrating some really good skating drills to improve your quickness. https://jhanhky.substack.com/p/improve-your-first-3-steps-e2b
I don't think you'll have to subscribe to the newsletter to view the videos, but if so the free version is very good.
The skating coach is Paul Matheson. He has a lot more video on his Instagram page: https://www.instagram.com/paul__matheson/
