I am planning to build a "diy leg press attachment" for my squat rack. I've sketched out some plans from my own noggin and other online posts. The way I'm planning it would allow me to do a few exercises with it like calf raises, standing calf raises, hack squats, leg presses, etc. Basically, anything that operates with a lever arm.

All that said, and I know what you are thinking: "damn, that Cylon357 is one sexy mf'er", keep your eyes up here, because my question is coming:

are vertical leg presses as bad for you as "they" say?
