Massaging assembly with movable lower-back supporting member

A massaging assembly, comprising:

• a massaging apparatus including a hollow casing with a top wall and a front wall, a rest member, and a driving unit mounted in said casing, said rest member being disposed on top of said driving unit and above said top wall of said casing, said casing having a first side and a second side opposite to said first side, said driving unit extending through said top wall of said casing so as to connect with and drive reciprocatingly said rest member from said first side to said second side;
• and
• a movable lower-back supporting member to be disposed spacedly from said front wall of said casing, said supporting member having a longitudinal axis parallel to the direction of reciprocating movement of said rest member, said supporting member including a base and a slide plate mounted slidably on top of said base, said slide plate being slidable in a direction parallel to the direction of reciprocating movement of said rest member;
• whereby, when said massaging assembly is in use, the lower-back portion of a user lying on his back is supported on the supporting member while the head or the ankles of the user are supported on the rest member, and muscles of the user are stretched due to reciprocating movement of the rest member and due to inertial forces that are generated on the user's center of gravity.
