Push-up trainer

A push-up trainer comprising:

• an elongated base having a top surface with a pair of ends, an edge, a lip extending upward from said top surface's edge and inward over said top surface, and a plurality of holes within said top surface extending linearly between said ends, said top surface having a low coefficient of friction;
• a pair of handle assemblies, each of said handle assemblies comprising:
• a sliding member slidably mounted on said base's top surface, said sliding member being elongated in the same direction as said base, said sliding member having a pair of flat side edges fitting within said lips, said sliding member having a low coefficient of friction, said sliding member having a rotating shaft and a plurality of holes surrounding and equidistant from said shaft, said sliding member further having a locking pin corresponding to said holes in said base's top surface, said locking pin having an end and a knob opposite said end, said knob having a cutout, said sliding member having a shelf corresponding to said cutout, said locking pin having a locked position wherein said end fits within said holes in said base's top surface and said shelf fits within said cutout, and an unlocked position wherein said end is retracted from said holes in said base and said knob sits atop said shelf, and said locking pin being spring-biased in said locked position;
• a rotating plate rotatably attached to said sliding member's rotating shaft, said rotating plate being round and having a low coefficient of friction, said rotating plate further having a locking pin corresponding to said holes in said sliding member, said locking pin having an end and a knob opposite said end, said knob having a cutout, said rotating plate having a shelf corresponding to said cutout, said locking pin having a locked position wherein said end fits within said holes in said sliding member and said shelf fits within said cutout, and an unlocked position wherein said end is retracted from said holes in said sliding member and said knob sits atop said shelf, and said locking pin being spring-biased in said locked position;
• a handle, said handle being an elongated cylinder having a first end, a second end, and a diameter, said first end having a round protrusion having a smaller diameter than said cylinder, said handle having a central bore, said central bore being round at said second end, and having a square portion at said first end, said handle having a handle pin fitting within said central bore, said handle pin being round with a square knob, said square knob being dimensioned and configured to fit within said square portion of said central bore;
• a first and second arm upwardly depending from said rotating plate, said second arm defining a round hole, said first arm defining a round recessed portion dimensioned and configured to support said handle's round protrusion, said recessed portion having a square hole and a square indentation rotated 45° from said square hole, said square hole and square indentation being dimensioned and configured to receive said handle pin's square knob;
• and
• said handle pin having a locked position wherein said square knob fits within said square portion of said central bore and said first arm's square hole, and an unlocked position wherein said handle fits within said square indentation of said first arm, said handle pin being spring biased towards said locked position.
