An exercise machine resistance adjustment system for providing an exerciser the ability to immediately adjust the resistance force by changing their body position on the movable carriage or end platforms. The exercise machine resistance adjustment system generally includes a frame, a carriage movably positioned on the frame, a spring connected to the carriage to apply a biasing force to the carriage, one or more left projections within the carriage adapted for a left hand of an exerciser to grasp, and one or more right projections within the carriage adapted for a right hand of an exerciser to grasp. The exerciser is able to efficiently adjust the amount of resistance force applied to the carriage by repositioning their hands (or feet) from a first set of projections at a first distance to a second set of projections at a second distance from the first end of the exercise machine.

Provided is an articulating bench configured to support a user, comprising a longitudinally-extending frame structure pivotably supporting back-supporting and independently-pivotable leg supporting portions. Removable arm supporting portions may be provided that pivot about the back supporting portion. In various example embodiments the articulating bench structure may be foldable for compact storage. Various adjustment mechanisms and methods of use are disclosed.

A reversible resistance exercise machine for reversing the direction of applied resistance against a movable platform of an exercising machine. The exercise machine has a frame, a carriage movably positioned upon the frame, and a plurality of biasing members. A plurality of first tension connectors are accessible near the first end of the carriage and are adapted for removably attaching selected biasing members near the first end of the carriage to resist motion of the carriage in the first direction. A plurality of second tension connectors are accessible near the second end of the carriage and are adapted for removably attaching selected biasing members near the second end of the carriage to resist motion of the carriage in the second direction. A user selectable amount of force may be applied to the carriage to resist movement in either of the first direction and the second direction.

A device including a first member for supporting a user; and a second member 14, attached to the first member, including a counterbalance portion. The first member and the second member are each moveable, and operable to slide with respect to each other in opposite directions, between a first position and a second position. The device can be operable such that between the first and second positions, the combined center of mass of the device 10 and its user remains substantially fixed. This serves to reduce the extent of forces and vibrations generated by use of the device on the object to which the device is located.

An exercise machine with electromagnetic resistance selection for changing exercise resistance settings by engaging more or fewer resistance biasing members using a electromagnets. An example implementation includes a movable carriage configured to move substantially along the length of one or more rails. A plurality of resistance biasing members are removably attachable between a stationary biasing member bracket affixed to the machine structure and the movable carriage. A controller changes the resistance settings against the movable carriage by electrically attaching or detaching any preferred number of resistance biasing members between the machine structure and movable carriage.

An upper body support assembly for use with an associated railed device having first and second rails is disclosed. The assembly includes first and second upper body supports capable of moving along the first and second rails, respectively. The upper body supports have at least one of: (i) first and second forearm supports, (ii) first and second hand grips, or (iii) a first forearm support and a first hand grip. An interconnecting member extends between and selectively connects both the first and second upper body supports to permit (i) interrelated movement therebetween when connected, and (ii) independent movement therebetween when disconnected. The assembly can achieve two point gait, three point gait, and four point gait movement.

An elliptical stepper includes a base, a damping device mounted on the base, two crank devices respectively laterally mounted to two opposite sides of the damping device. Each crank device has a stepping device mounted thereon and each stepping device has a roller set mounted to a bottom thereof, wherein the roller set is universally rolled relative to a corresponding one of the two stepping device. The base includes two opposite sides each having a guiding structure disposed thereon. Each guiding structure includes at least one rail having a front end outwardly extending relative to a center line of the base. Each roller set is moved along a corresponding one of the two guiding structures such that each stepping device provides a wiggling effect when moved along an elliptical route.

An exercise machine with adjustable handles that provide for multiple handle positions. The exercise machine with adjustable handles generally includes a frame with one or more rails, a carriage movably positioned upon the rails, and a pair of adjustable handles positioned near an end of the frame. The adjustable handles each have a handle portion that is movably connected to a corresponding handle stanchion to pivot from a storage position to an extended position.

An exercise machine adjustable resistance system and method for efficiently varying the workout resistance for an exercise machine. The exercise machine generally includes a carriage movably positioned with respect to the at least one rail, a plurality of springs selectively connectable to the carriage to provide a resistance level to the carriage, a plurality of electrically actuated mechanical devices adapted to latch a corresponding one of the plurality of springs to the carriage when in the latch state and unlatch a corresponding one of the plurality of springs to the carriage when in the unlatch state and a control unit in communication with the plurality of electrically actuated mechanical devices to selectively control the state of each of the plurality of electrically actuated mechanical devices to be within the latch state or the unlatch state.

An exercise machine carriage handle system for providing handles for an exerciser to grasp with their hands thereby expanding the type of exercises that may be performed. The exercise machine carriage handle system generally includes a frame having a track, a carriage movably connected to the track, a bias member connected between the frame and the carriage, a first handle connected to the carriage near the first side, and a second handle connected to the carriage near the second side. The first handle and second handle are adapted for grasping with a first hand and a second hand respectively of a user during the performance of an exercise on the exercise machine.
