The small plates that make progress possible. Change plates let you add 5 or 10 pounds to the bar instead of jumping 25 at a time, which is how pressing and pulling numbers actually keep moving. Cast iron, sold in pairs, with a standard 2 inch collar opening for any Olympic barbell.
Weight:15lb Bundles (5lb, 2.5lb pairs)
Genuine PRx Performance
Synergy Custom Fitness is a PRx Performance retail partner. Every PRx free weight on our site is the same gear PRx sells directly, fulfilled and shipped to your door by PRx itself.
Progress Lives Here
Strength is built in small jumps. A pair of 2.5s turns an impossible 5 lb PR attempt into a repeatable one, week after week. That is how strength compounds.
Compact Cast Iron
Iron packs weight into a small diameter, so change plates stay out of the way on the sleeve and leave room for the big plates.
The 15 lb Bundle
One bundle option delivers 5 lb and 2.5 lb pairs together, the two increments every progressive program leans on most. One order covers your microloading.
Fits Every Olympic Bar
The 50.6mm collar opening slides onto any standard Olympic barbell sleeve, from your main bar to the E-Z curl. No adapters, no spacers, no fuss at all.
Stores With Everything Else
Synergy plate storage racks and wall mounted holders keep change plates ordered by size next to your bumpers instead of buried under them on the floor.
