  • 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.
