1. An exercise machine, comprising:
a frame having a rail;
a movable platform movably positioned upon the rail, wherein the movable platform comprises a first end and a second end opposite the first end of the movable platform;
a first bias member selectively connectable to the movable platform to apply a first resistance force upon the movable platform;
a first switch connected to the movable platform, wherein the first switch has an engaged position and a disengaged position; and
a first latch adapted to be selectively connectable to the first bias member, wherein the first latch has an engaged position and a disengaged position, wherein the first latch is adapted to be manipulated by the first switch into the engaged position or the disengaged position, wherein the first latch is connected to the first bias member so as to apply the first resistance force upon the movable platform when the first latch is in the engaged position, and wherein the first latch is not connected to the first bias member when the first latch is in the disengaged position;
wherein the first switch comprises a magnet, wherein the magnet of the first switch is adapted to magnetically attract the first latch when the first switch is in the engaged position.
