Abstract: Embodiments of antimicrobial weight plates with an antimicrobial copper alloy, preferably a cuprous nickel alloy, preferably the alloy contains approximately 91% copper and approximately 9% nickel. A first embodiment having a core weight plate and one or more weight plate handles coupled in a circumferential edge of the core weight plate, the weight plate handles with antimicrobial grip surfaces are each formed from the antimicrobial copper alloy. A second embodiment having a core weight plate in a shape of an annular disk formed from an antimicrobial copper alloy. A third embodiment having an antimicrobial weight plate including two antimicrobial weight plate surfaces, each including the antimicrobial copper alloy, and a core weight plate sandwiched between the two antimicrobial weight plate surfaces. A fourth embodiment having a core weight plate, and an antimicrobial copper alloy coating thermally sprayed on to the core weight plate.
