This is one educational:
IceSkating.London - YouTubeIt's mainly former UK olympic competitor Marika Humphreys Baranova who coaches at Lee Valley and Alexandra Palace, with bits of her husband and dance partner Vitaly. The snippets are quite short and focus on one thing at a time. IMO her technique and explanations of it are exceptional and just a joy to watch. I used to see her skating for fun at AP in her downtime between lessons, and I could watch her all day. So nice when coaches still show much they love being on the ice - inspirational. She's in amazing shape for her age.
This one is pure eye candy:
On Ice Perspectives - YouTubeHe skates around with some kind of lightweight steadicam thing behind skaters doing performances or in training. There's a lot of content here, ranging from top champions to relative unknowns - whatever your preferred style or discipline or skater there's sure to be something for you here, and the closeness gives a sense of the speed and precision that you don't get from the typical footage of competitions and performances shot from a distance.
