Do any of you KMA practitioners perform any supplemental training similar to what some Okinawan styles refer to as Hojo Undo? If so, what do you call it? Bojo Undong? 보조운동? I have seen the term Junbi Undong (preparatory movements/exercises) used for warm up calisthenics, but not the body conditioning/hardening exercises similar to those of Uechi Ryu or Goju Ryu. I imagine that since neither of these styles gave much (if any) contribution to early TKD that traditions like this likely do not exist within the KMA's, but I'm curious if anyone practice these exercises.
