PRx Cast Iron Olympic Plates are dense, compact and honest — the plates you load for squats, presses and pulls where the bar never leaves your hands.

Bumper plates are the right call for anything you drop, but for benching, strict pressing, rowing and back squats they waste sleeve space and add nothing. Cast iron solves that: the same 45 lb in 1.4\" instead of 3\".\u003c\/p\u003e\n\u003cp\u003eThe size range here matters as much as the material. Small increments are how strength actually gets built, and a pair of 2.5 lb plates at 6.5\" across is the difference between adding five pounds to a lift and stalling for a month. Working up from there, the 10 lb at 9\" and the 25 lb at 11\" fill the gaps that a bumper-only set leaves wide open.\u003c\/p\u003e\n\u003cp\u003eAll six sizes share the same 50.6mm collar opening, so they mix freely with your bumpers on the same bar and load onto standard plate pegs.
