Adjustable center mass weight apparatus

A method for using an adjustable center mass weight apparatus, the method comprising:

• providing the adjustable center mass weight apparatus comprising:
• a generally spherical, hollow core member defining a cavity therewithin, between a top end and a bottom end of the generally spherical, hollow core member;
• a grip handle disposed centrally inside the cavity of the generally spherical, hollow core member, along a horizontal axis transverse to a central axis of the generally spherical, hollow core member;
• a plurality of core grooves disposed at the top end and the bottom end of the generally spherical, hollow core member;
• and
• a plurality of incremental weight members configured to engage with the plurality of core grooves at the top end and the bottom end of the generally spherical, hollow core member, without disrupting weight distribution of the grip handle, wherein the plurality of incremental weight members comprises a top weight member, a bottom weight member, and a top handle attachment;
• assembling the adjustable center mass weight apparatus, comprising:
• attaching the bottom weight member to the bottom end of the generally spherical, hollow core member by engaging the plurality of core grooves at the bottom end of the generally spherical, hollow core member with corresponding weight grooves of the bottom weight member;
• and
• attaching one of the top weight member and the top handle attachment to the top end of the generally spherical, hollow core member by engaging the plurality of core grooves at the top end of the generally spherical, hollow core member with corresponding grooves of the one of the top weight member and the top handle attachment;
• gripping one of the grip handle and the top handle attachment of the assembled, adjustable center mass weight apparatus, with a hand of a user, wherein the grip handle is configured to distribute weight of the adjustable center mass weight apparatus evenly around the hand of the user, and wherein the top handle attachment is configured to convert the adjustable center mass weight apparatus into another weight apparatus;
• and
• maneuvering the adjustable center mass weight apparatus through the gripped one of the grip handle and the top handle attachment during one or more of a plurality of exercises.
