Yaar, in the lift it's all about the net force, not just weight! When it accelerates up, the floor pushes you harder than *mg*, so your apparent weight increases. We just did this in physics class with free-body diagrams.
But let me tell you, I feel it every morning when my old van struggles up the hill to the orchard with a full crate load—my back presses into the seat way more than when it's just parked on flat ground. The van is my lift, and the apples are my extra *mg*!
