ckd means cyclical ketogenic diet, meaning you go a few days without carb, and then do a carb-load.
what one might do to train hst style while on a keto diet is follow a tkd, targeted ketogenic diet, in which you'd consume carbs before every workout, but just enough to fuel the workout, so that you get back into ketosis after the workout. however, i believe this protocol wouldn't be optimal for muscle growth. now, if the objective is only fat loss, it could work very well.
