I have also been trying to get to watching some Judo videos on YouTube, a couple of channels that I like are:
Dojo Outfitters - https://www.youtube.com/channel/UCT-lZUImP2-eOW6Y8GBCbhw (they have a mix of Judo and JJ videos, but I find both sets useful).
Efficient Judo - https://www.youtube.com/channel/UC1CsWk5MTssfFt6rb7CXKKA
There is also a great instagram account from Israel that does these excellent matrix-style breakdowns for ground work - https://www.instagram.com/timura_bjj/
All three are worth checking out, and please follow us on IG.
Thanks for reading.
