In the 30 years I participated in recurrent training (ugghhh) at AMR, we did many many aproaches to stall in the simulators. Most usually, the instructor (sim instructor or CKA) would have the trainees level at perhaps 10,000 feet, handflying the sumulator. No auto-throttles. The sim instructor would set the power very low and tell the pilots to leave the throttles alone until the first indication of impending stall (ie, stick shaker) and not to trim the simulator. The recovery was to shove the throttles full forward/ ask for max power, keep the wings level, minimize altitude loss and fly out of the situation. The same thing was repeated in a left or right turn; trimming as necessary.
