Since I started lifting heavy I've used the power rack to do what I guess could be called rack presses not sure.
I use this for breaking barriers in squats.
I set the rack so when I get under the BB my legs will be at a 90 degree angle. From there I just load weight until I can only about 1 max rep. Then when I go to free squat I can always usually go heavier than normal.
This has always worked well for me when I get stuck at a certain weight. Just didn't know if there was a name for this. (some dude asked me in the gym so this is why I ask all of you vets)
