A variable-resistance exercise machine with network communication for smart device control and brainwave entrainment, comprising an exercise machine with a plurality of moving surfaces, that each provide an independent degree of resistance to movement, a sensor that detects movement and provides output to a controller, a brainwave entrainment manager that selects a brainwave entrainment frequency based on the sensor output, and a controller that receives an input from a user device, changes the operation of the plurality of moving surfaces based on the input, and sends the brainwave entrainment frequency to the user device.

A linear powered input device that utilizes linear input from a user and converts the linear input rotational energy to perform work. The linear input is generated by lever arms having a slotted attachment at a pivot point that allows a free end of the lever arms to move linearly rather than in an arcuate path. The lever arms are connected to a power transmission mechanism that wraps around one or more drive wheels having one-way bearings mounted on one or more output shafts. The output shafts can be connected to any type of auxiliary device to perform the desired work. Output wheels may be mounted on the output shafts and operatively connected by a transmission link that allows linear motion of any lever arm in any allowable direction to cause the output shaft to rotate in the same rotational direction so as to receive continuous input.

A stationary exercise device includes a support structure and one or more input members such as pedals, handles, or other feature movably connected to the support structure. A movable output member such as a wheel is movably mounted to the support structure, and operably connected to the one or more input members such that movement of the one or more input members causes the output member to move. A resistance member interacts with the output member when the output member is moving to generate a variable resistance force tending to prevent movement of the output member. The variable resistance force may at least partially simulate the effects of inertia and/or momentum.

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.

An end platform for an exercise machine for increased support of an exerciser's spine, neck and head which allows for an expanded scope of exercises that cannot otherwise be performed on the machine without the improved platform. The end platform for an exercise machine generally includes a novel, ergonomically improved stationary platform affixed to at least one opposed end of a substantially longitudinal exercise machine that includes at least a resistance biased reciprocating platform. The improved end platform provides for increased support of exercisers' spine, neck and head, thereby allowing for an expanded scope of exercises that cannot otherwise be performed on the machine without the improved platform, and further provides for the attachment of new and novel exercise equipment accessories to the exercise machine.

An exercise machine monitoring and instruction system for the movement of an element of an exercise machine by an exerciser and providing automated feedback to the exerciser to help improve the exercise in real-time. The exercise machine monitoring and instruction system generally includes an exercise machine having a movable element that moves between a first position and a second position in a reciprocating manner, a sensor that detects a real-time position of the movable element, a processor in communication with the sensor to receive the real-time position data from the sensor related to a position of the movable element and a feedback device in communication with the processor that provides real-time instructions to the exerciser on how to adjust their workout to achieve a desired result.

A transmission structure of a climbing machine for an operator to operate in a standing position is disclosed. The transmission structure of the climbing machine includes a base, a support frame, a first slide rail, a second slide rail, a first transmission unit, a second transmission unit, a first handle slider, a first pedal slider, a second handle slider, a second pedal slider, and a resistance unit. The climbing machine is used to train the synchronized and coordinated movements of hands and feet for simulating rock climbing and mountaineering. The support frame, the first slide rail, the second slide rail, the first transmission unit and the second transmission unit are all located at the center line position of the upright trunk of the operator. The volume of the climbing machine can be reduced greatly to save the space occupied.

A foldable gymnastic machine comprising a supporting structure to rest said gymnastic machine on a resting surface, comprising a front portion, comprising in turn a resistance member, and a rear portion, an exercise device, through which a user performs a gymnastic exercise, coupled to said supporting structure and to said resistance member, capable of resisting during the execution of a gymnastic exercise, said exercise device comprising a second pair of levers for the feet, in turn comprising a first and a second lever, each provided with a first end, coupled to said supporting structure, and a free second end, capable of fitting said user's feet during the execution of the gymnastic exercise, said gymnastic machine being characterized in that said first and second lever of said second pair of levers for the feet are capable of passing from an open position, in which the user can perform the gymnastic exercise, to a closed position, when the gymnastic machine is not in use.

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.
