An exemplary incremental weight for an exercise system has a generally annular magnet encapsulated within a coating which cushions the magnet, protecting it both from becoming damaged, and from damaging an exercise apparatus, while promoting the adhesive properties of the magnet. In a first exemplary embodiment, the coating comprises a first annular rib and a second annular rib extending respectively about outer and inner peripheries of the generally annular magnet, and a plurality of ribs extending radially between the first and second annular ribs. The generally annular magnet, in exemplary embodiments, comprises at least one of a ceramic magnet, ferrite, or an alnico magnet. Exemplary coatings may be elastomeric, molded silicone, or anti-slip coatings. In another exemplary embodiment, a plurality of mounting pads are attached to a surface of said weight defined by an annular surface of said magnet.
