I've been doing aikido since last year, and I am still having trouble with this technique. Uke comes in with a tsuki and I am supposed to step back and catch his wrist, turn it over, then walk behind him for a rotational irimi nage.

I can't seem to find any videos on Google or YT of anyone doing this technique. But, I can find a lot of videos of nage deflecting the tsuki and entering without stepping back. My teacher says to just do it and figure it out later.

Will this technique get easier to do? Is this good irimi nage practice if I am stepping back?

Thank you for your help!
