You don't have to spin your body. You can do theI'm only doing ushiro geris and tobi ushiro geris (my favourite kick anyway). There's no reason to do anything else! Even just design an entire martial art system based solely on those. Hey I've seen weirder!
- side kick instead of turning back kick.
- hook kick instead of turning hook kick.
This way, you don't have to worry about your opponent from moving in when your body is spinning while standing on 1 leg.
