Narrative:

I was the r-side. Aircraft X was IFR [VOR1] direct to [VOR2] at 6;000. Aircraft X went into a 7;000 mia at which point I issued a low altitude alert. Training was being performed on the d-side during the event. I was too casual today at work. I was not engaged in the operation which resulted in the event.
