The rack

Modular trainer. Wraps around your own dumbbell handle. Build the shape, add the weight. Train incrementally for the blobs you'll have to face one day.

Fingertip work, trained without the plate. Implements built around a center roundish hub. Same grip a plate hub demands, but weirder.

Thumb against the side of your index finger — the grip you'd use to hold a key. Anything lifted that way counts, key-shaped or not. Do it enough and you'll grow the calluses to prove it.

Thick, upright, no good angle to pull from. Your grip gives out before your back does.
