I like paused lifts, but not on all movements. To me the pause has to serve a purpose. I like to use it on front squats for example to really work on perfect body position. Pausing at the bottom while focusing on lifting the chest up as much as possible and keeping the torso as upright as you can.
I also personally like it on back squats because I'm so efficient at utilizing the stretch reflex that I get a better muscle stimulation for paused squats.
But reallym, the layer approach is not about using specific methods. But in using a sequence of different methods or loading scheme on an exercise to create a greater training effect.
For example one could do:
LAYER 1 - Paused back squat, ramping to a 2RM
LAYER 2 - Back squat, start where you finished layer 1 and ramp up to a 2RM on a normal squat
LAYER 3 - Bottom half squat: go all way down. That is the starting position. Rapidly go up to the half squat position, lower back down slowly, do 8-10 reps like that, never going above the half squat, always going up fast and going down slow. 3 sets of 8-10
LAYER 4 - Barbell jump squats with 20-30% of the 2RM: dip down into a half squat and jump up as high as possible. Reset before every rep. 2 sets of 5
That is an amazingly effective lower body session for size, strength and power.
