Exactly as previous post says.
Heres the profile from Flight Safety... (CJ2)
1. level flight , a/c clean
2. set power to 50%, maintain alt & trim as required
stick shaker or buffet (whichever occurs 1st)
3. to recover apply max allowable power for alt/temp and call for flap t/o approach.
Maintain same pitch attitude, keep wings level.
Allow speed to increase to V2 +10 and retract flaps.

Just my 2d worth on this type of training and what you are trying to achieve. (I am not familiar with the type of a/c in question btw)
The 'approach to stall' and the 'stall' require different recovery techniques. An approach to stall, i.e. recovering at the stick shaker or light buffet, whichever comes first, is a matter of applying max thrust whilst keeping alt/ht loss to a minimum - it's not necessary or desirable on most types to shove the c/column forward - just use thrust to accelerate the a/c to a lower, and safer angle of attack with the minimum height loss. I'm intrigued to hear that on the a/c in question, selecting flap of any amount is recommended because on most types there is a maximum altitude for flap selection and I would have thought that a recovery technique would want to be valid for any altitude - surely?
Recovery from a full stall (i.e. AOA beyond max CL) is different. It is essential to reduce AOA and to do this you need to move the c/column positively forward as part of the recovery. Height loss, maybe considerable height loss, is inevitable.
Just out of interest, on the types in question, are there different recovery techniques for a clean approach to stall depending on altitude - or is there no altitude limitation for flap selection?
Cheers
