While standing, your engaging a heck of a lot more synergist muscle groups to stand, thats why posture matters.
machines, like the leg press, isolate the muscle for the exercise. Making it reliant on a singular muscle group. When working with such intensity this way, snap city is common is you push it too much on... pretty much any part of the body, we're all joints and ligaments, in the end. And you can't work those.

those leg presses have about 2000lbs when it is a gym goer that isn't someone recovering from some sort of ailment. and because of the angle of the machine it is about 70% of the weight. Do you deadlift 1400lbs?
