Okay my iron brothers and sisters, doin some research on this subject.

Internet is full of varied answers.
Just wondered what some of you thought about this.
If a beginner to training is thinking they are at a plateau, is it time to do intermediate work?
At what point should you consider yourself an intermediate lifter?
Advanced lifter?

Some of my findings tell me that it is all about the mastery of periodized training, understanding intensity, form being spot on, knowing how to mix various exercises for effect rather than just a workout and most importantly, connecting the mind and muscle together.

Your thoughts are appreciated.
Thanks!
