If you ever tried to find some good educational videos about ukemi there’s a good chance that you stopped looking right when Donovan Waite “Meeting the Mat” explanations were found. You may get no idea why it’s attractive but you will get the feeling that everything should work just like that because of the softness and smoothness of the moves.
Donovan Waite (1958 – Feb 21, 2021) got his Shodan at the age of 14. Through years of practice, he had a chance to learn from a lot of foremost instructors and spent over ten years as Yamada Sensei‘s uchi-deshi.
He was doing Aikido for almost 50 years and was a 7th Dan Aikikai certified Shihan. He was a great example of the Aikido skills in the hand of a physically big person. Just watch his ukes flying.
In the late years Sensei was teaching in his Philadelphia Dojo and all around the world. There are a lot of videos with Donovan Waite teaching. He was really creative with the moves.
There’s also Aikido remote product named Aikido3D made by the Sensei which is good but remember that going to the Dojo is the only possible way to learn the art properly.
