Preloading a bar for deadlift
This will likely be a stupid question but I've been reading about the ways of damaging even high-end barbells and have become paranoid.
I bought two high quality barbells so I can use one for squats/bench press/overhead press that I keep unloaded on my squat rack after my work-out. The other one, I keep on my platform loaded with a pair of 45# plates. This is because I can tweak my back easier loading that first pair of 45 pounders than actually doing my deadlifts with 3 pairs. I understand that keeping a loaded bar in a rack can bend and damage it.
My question is whether leaving a loaded bar on the platform continuously can also damage a bar. I'd think that the only deforming stress to the bar would be the minimal weight of the steel of the part of the bar between the plates. Will a high quality bar stand up to that minimal deforming force of being kept loaded 24 hours a day sitting on the floor?
