It's only because I'm using a lever plate loaded hammer strength hack squat. I bottom the thing out but it doesn't require nearly the core strength/stability compared with a barbell squat or hack squat which is an area I need to work on. It's basically all legs but I like the machine a lot because the motion closely mimics a squat and I can drive a lot with my hips. Probably closer to a squat than a hack squat.
