Air carrier technician reported that during training on a B-757; they noticed that two doors were still in the armed position. They disarmed the doors and the escape slide did not deploy.

Narrative

I went upstairs to the cockpit to show a trainee around a 757 when I noticed that door 1L and 1R were left armed. I disarmed the doors and then proceeded to check all other doors to make sure no other doors were armed.
