  • Patent number: 10065062
    Abstract: An apparatus and method operably coupled a movable member of an exercise apparatus to a carriage such a movement of the movable member moves the carriage along a rail. A magnetic portion carried by the carriage induces eddy currents in the rail to resist movement of the carriage along the rail to resist movement of the movable member.

  • Patent number: 9186537
    Abstract: An exercise apparatus comprises an incremental weight system. The incremental weight system comprises an incremental weight and an incremental weight selector. The incremental weight selector is liftable by a weight lift and has a lever movable between a lowered position and a raised position to actuate the selector between an engaged position engaging the incremental weight such that the incremental weight is liftable with a first weight by the weight lift and a disengaged position disengaged from the incremental weight such that the first weight is liftable independent of the incremental weight.

  • Patent number: 8663072
    Abstract: An exercise device includes first and second coupling systems at each comprise a flexible element. In one implementation, the exercise device further comprises a step height adjustment mechanism. The flexible element of the first and second coupling systems couples at least one crank to a right foot support and a left foot support. The step height adjustment mechanism allows a person to adjust a step height of a path through which the left and right foot supports move.

  • Patent number: 8419598
    Abstract: An elliptical exercise device including a frame having a pivot axis, a foot link, a coupling, a swing arm, an engagement mechanism, and a guide system. The foot link has rearward, forward and foot support portions. The foot support portion has a central location. The coupling couples the rearward portion to the pivot axis so that the rearward portion of each foot link travels in a closed path relative to the pivot axis. The engagement mechanism has a first portion coupled to the swing arm and a second portion coupled to the foot link at a location rearward of the central location. The guide system supports the forward portion of the foot link along a preselected reciprocating path of travel as the rearward portion of the foot link travels along its path of travel. The guide system is selectably positionable in a plurality of different positions.

  • Patent number: 8105213
    Abstract: An exercise apparatus includes a foot member configured to pivot about a horizontal pivot axis, the foot member supporting a footpad, a first surface coupled to the foot member to pivot with the foot member about the horizontal pivot axis, a second surface stationarily supported by the frame, and a bumper between the first surface and the second surface. The bumper resiliently compresses during pivoting of the first surface in the arc towards the second surface while in contact with the first surface and the second surface.
