Exercise method and device

An apparatus for lower body exercise comprising:

• a frame supporting a seat,
• a pivot axis assembly having a pivot axis positioned proximate to the seat
• wherein the pivot axis assembly comprises a housing, a bearing and a pivot member,
• wherein the pivot member comprises a right pivot member and a left pivot member configured to rotate about the pivot axis,
• wherein the right pivot member and the left pivot member are coupled to enable power transmission such that the left pivot member rotates counterclockwise when the right pivot member rotates clockwise, further comprising:
• a left arm and a right arm;
• each arm coupled to the left and right pivot members, respectively,
• a left arm elongation mechanism and a right arm elongation mechanism coupled to the left and right arms, respectively to allow extension and contraction of the arm,
• left pedal and a right pedal rotatably coupled to a distal end portion of the left and right pivot arm elongation mechanisms, respectively, and
• one or more resistive force generatingunits, wherein resistive force generated by the one or more resistive force generating units is transmitted to the pivot member and the arm elongation mechanism,
• wherein, when a user pushes each of the pedals, a length of the each arm increases relative to the each pivot member and subsequently returns to an original length,
• wherein the apparatus enables the user to simultaneously perform a compressing action by pushing the pedals and perform a movement in which a user's legs rotate vertically about a hip joint as an axis;
• and
• wherein each pedal, when viewed from the side, moves forward from a seating section in a forward direction relative to the seat, then moves downward to an end section, and then reverses direction and is automatically returned to an exercise start section along a reciprocating path defined by rotation about the pivot axis and extension and contraction of the arm telescopic mechanism, a trajectory of each pedal being reciprocating, non-circular and characterized by having an area;
• and
• wherein the right arm and the left arm do not rotate continuously about the pivot axis and do not rotate circular during exercise.
