An exercise machine tension device securing system for safely and efficiently securing selectable biasing members to an exercise machine. The exercise machine tension device securing system generally includes an exercise machine including a frame and a carriage movably positioned on the frame. A plurality of tension devices may be connected to the frame at one end; with the other end being removably connected to the carriage by a selection device. The selection device may include a plurality of slots for removably receiving one or more of the tension devices to secure the tension devices selectively to the carriage. A securing member movably connected to the selection device includes projections adapted to selectively enclose the slots so as to secure the tension devices within the slots of the selection device.

A frame corner member includes an elongated hollow extrusion having a central corner portion and two leg portions extending from the central portion. Each leg portion includes an inner side wall spaced from and parallel to an outer side wall, and merging with the central portion. An outer end wall joins the inner and outer side walls, which each include an inner surface facing the inner surface of the other side wall. An opening through the outer end wall defines a space between the inner and outer side walls adjacent one end of the extrusion for receiving one end of one of frame side members and end members. At least one of the inner surfaces in the space has discrete surface features adapted to grip and retain the one end of one of the side members and end members in the space when received through the opening.

An improved exercise machine has a stationary longitudinal monorail structure that extends between front and back end stationary exercise platforms, and an exercise platform mounted on a levitated carriage that is reciprocally movable along the monorail between the stationary platforms. Magnetic elements arranged on various opposing surfaces of the carriage and monorail generate magnetic forces that levitate and stabilize the carriage as it moves relative to the monorail thus substantially eliminating contact friction. Springs selectively attachable to the movable platform provide a resistance force for exercising. Pseudo-levitation and eddy brake elements on the carriage and monorail structure further stabilize the carriage and platform.

Disclosed herein is an exercise machine that includes an elongated frame having a head end and a foot end, and a moveable carriage slidably coupled to the elongated frame and moveable between the head end and the foot end, the moveable carriage having a spring bracket coupled to an underside of the moveable carriage. The exercise machine also includes a spring support rod slideably coupled with the elongated frame and disposed adjacent the foot end, and selectively positionable with reference to the foot end by a handle that extends from an interior area of the elongated frame to an exterior area of the elongated frame. The exercise machine also includes at least one resistive member coupled at a first end with the spring support rod and at a second end with the spring bracket, and configured to bias the moveable carriage towards the foot end of the elongated frame.

An exercise machine with resistance selector system for selecting the number of bias members applying a resistance force against a movable platform. The exercise machine with resistance selector system generally includes one or more switches which are connected to the movable platform. Each of the one or more switches is adapted to engage or disengage a corresponding latch. When engaged, the latch will connect a corresponding bias member to the movable platform. When disengaged, the latch will disconnect a corresponding bias member from the movable platform. In this manner, an exerciser may easily adjust the number of bias members connected to the movable platform so as to adjust the resistance force applied against movement of the movable platform along a rail.

An exercise device is disclosed which is safe to use, resists muscle adaptation, incorporates multiple methods of resistance, can quickly and easily switch between exercise modes to provide the user with the most optimal exercise routine and the least amount of hassle, and can otherwise remove the limitations of prior art machines. The exercise device can be utilized by the user to perform rowing exercises targeting cardiovascular training, high intensity training, strength training, muscle-building training and core building. Moreover, the exercise device is easy to use, will have multiple methods of operation, can quickly and easily switch between these methods of operation, and will not limit the user in the types of exercises to be performed.

An exercise machine ergonomic handle system for providing hand-holds for the performance of exercises with reduced flexion and/or extension of the hand and wrist and reduced ulnar and/or radial deviation so as to reduce injury and allow application of full strength to the exercise machine. The exercise machine ergonomic handle system generally includes a longitudinally extending frame, a carriage that moves upon a first longitudinal portion of the frame, and at least one pair of ergonomic handles positioned on a second longitudinal portion of the frame. The ergonomic handles rotate about an axis to prevent flexion and/or extension, and can be positioned at a width and/or angle that reduces ulnar and/or radial deviation.

The present invention relates to the field of fitness training devices and exercise machines. More specifically, a substantially horizontal exercise machine comprising an exercise platform slidable along one or more rails aligned with the longitudinal axis of the machine structure, the slidable platform spring-biased towards one end of the machine, is tiltable to allow for one end of the machine to be raised or lowered relative to the opposed end of the machine.

An exercise machine support system for providing increased versatility including inclination or declination of an exercise surface, a reduction in the overall length and width of the exercise machine, and an enhanced user interface which reduces the risk of injury. The exercise machine support system generally includes a cantilevered exercise machine which is adapted to have a variable angle of incline or decline with respect to a horizontal ground surface. The exercise machine will generally include a base and a support which extends between the base and the exercise machine. The upper end of the support is connected to the exercise machine by a first pivot such that the exercise machine pivots about the support. An adjustment device may be utilized to pivot the exercise machine and thus adjust its angle of incline. Various types of adjustment devices are disclosed, including an actuator, ratchet-and-pawl, gears, and cam.

A system for providing resistance in an exercise machine. The system includes a motor, at least one loop drive attached to the motor. A carriage is coupled to the loop drive. The carriage moves in a first direction when the motor is turned in a first direction and a second direction when the motor is turned in a second direction. At least one sensor is attached to the carriage, wherein the at least one sensor is configured to detect external force on the carriage. Information from the sensor indicates external force on the carriage. The information is used to determine a movement of the carriage in response to the external force. The motor is instructed to turn the loop drive to apply the movement.
