Weight plate

A weight plate for mounting on a barbell or dumbbell, comprising:

• a) a weight plate body having a central bore extending through said weight plate body;
• b) at least two radially extending flange members extending partially about the perimeter of said weight plate body, wherein each of said flange members include upstanding portions which project outwardly in opposite directions from said plate body said flange members defining gaps there between;
• c) at least one opening disposed adjacent the perimeter of said body generally aligned with at least one of said gaps;
• and
• d) wherein said flange members are adapted for locking adjacent weight plates against relative rotation.

A weight plate for mounting on a barbell, comprising:

• a body in a first plane, said body having an outer perimeter and said body having an inner bore extending through for coupling to said barbell;
• at least two flange members, each having a first dimensional component in a plane perpendicular to said first plane, said first dimensional component entirely existing in an area proximate to said outer perimeter,
• at least one opening extending through said plate and adjacent to said outer perimeter wherein at least a portion of said at least one opening is substantially aligned with at least a portion of a gap defined between two of said flange members;
• wherein said flange members are adapted for locking adjacent weight plates against relative rotation.

• c) at least one opening disposed adjacent the perimeter of said body and not disposed entirely within a flange member wherein at least a grippable portion of said at least one opening is substantially aligned with a gap defined between two of said flange members;
• and
• d) wherein said flange members are adapted for locking adjacent weight plates against relative rotation.
