You’re pulling some serious weight off the floor, but your gym doesn’t have a deadlift jack and you’re wearing yourself out wrestling plates on and off the bar.
Use another plate to prop up the bar for easy-on, easy-off access.
Roll one side onto a smaller plate so it sits in the hole and doesn’t move.
When you’re finished, roll the inside plate of one side back onto the plate.
Take the collar off the side that’s still loaded, then lift the other end of the bar.
Replace the barbell where you found it, and rack all your plates like the responsible Gym Flower that you are.
