• a stationary base including:
• a front elongated support structure;
• a back elongated support structure;
• and
• a support body coupled between the front and back elongated support structures;
• an elongated handle coupled to the support body and extending vertically away from the support body, the elongated handle including a first pivot assembly coupled to the support body, the first pivot assembly to allow the elongated handle to pivot about its vertical axis;
• and
• a knee supporting structure coupled to the support body, the knee supporting structure including:
• a second pivot assembly coupled to the support body;
• a first knee supporting structure coupled to the second pivot assembly, the first knee supporting structure extending horizontally away from the second pivot assembly in a direction opposite from the elongated handle;
• and
• a second knee supporting structure coupled to the second pivot assembly, the second knee supporting structure extending horizontally away from the second pivot assembly in a direction opposite from the elongated handle,
• wherein the second pivot assembly is configured to allow the first and second knee supporting structures to pivot about its vertical axis,
• wherein each of the first and second knee supporting structures includes a cylindrically-shaped body disposed adjacent to the second pivot assembly, the cylindrically-shaped body including a cavity for receiving a removable pin, and
