An exercise apparatus providing a User multiple different exercises, including both resistance movements and isometrics. The User interacts with the apparatus by grasping a bar. A resistance mechanism is symmetrically mounted on a second bar and provides infinitely variable resistance to the User, as well as soundproof operation. A vertical column allows infinite positioning of the bars for different exercises, and a bench provides support. The User can change the exercise resistance by verbal commands, or the apparatus can sense the torque applied by the user to the apparatus and vary the exercise resistance in response to the force applied by the User or the speed at which the user is moving the bar. The apparatus can be battery powered and operated at locations where electric service is unavailable, or in zero gravity. To verify accuracy, the resistance can be calibrated against a known quantity of weight.

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 unlatch state.

A stair exerciser apparatus for simulating stair climbing includes a frame, a lower shaft and an upper shaft mounted rotatably on the frame, a conveyor operatively engaged with the upper shaft and the lower shaft, a plurality of steps, a flywheel and a one-way clutch mechanism. The plurality of steps are joined to the conveyor for movement with the conveyor. The flywheel is operatively engaged with the conveyor. The one-way clutch mechanism is operatively engaged with the conveyor and the flywheel. The one-way clutch mechanism is configured to selectively couple the conveyor with the flywheel such that motion of the plurality of steps in a first step direction drives rotation of the flywheel when the one-way clutch mechanism is engaged, and the one-way clutch mechanism decouples the conveyor from the flywheel when the one-way clutch mechanism is disengaged.

Embodiments of a strength training apparatus and related methods are provided. In one embodiment, a strength training apparatus may include a tower, a first arm and a second arm each pivotally coupled with the tower and each being configured to be selectively positionable independent of each other at multiple angles relative to each other, a first pulley coupled to an end of the first arm, a first cable extending through the first arm and the first pulley, a second pulley coupled to an end of the second arm, a second cable extending through the second arm and the second pulley, a magnetic mechanism coupled to the first cable and the second cable and configured to provide multiple levels of resistance to a user pulling on the first cable and/or the second cable, and a control panel located on the tower.

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 exercise apparatus including a stationary exercise apparatus and a lever arm pivotably biased about a pivot axis. A support supports the lever arm above the stationary exercise apparatus, and a biasing device rotatably biases the lever arm with respect to the support about the pivot axis. The pivot axis extends substantially in a vertical direction, and the stationary exercise apparatus is a treadmill.

A resistive device that enables adjustable resistance in at least one direction using an attachment system and associated eddy current braking system. The resistive device can be bench-mounted, in some embodiments, used for physical therapy caused by neuromuscular diseases, such as stroke and cerebral palsy, orthopedic disorders, general disuse, or even for overall fitness.

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.

A stationary exercise machine may include reciprocating hand members, such as handles, and/or reciprocating foot members, such as foot pedals. The reciprocating hand members may be operative to apply a first moment to a crankshaft, and the reciprocating foot members may be operative to apply a second moment to the crankshaft. The second moment may be different than the first moment. The reciprocating foot members may cause a user's feet to move along a closed loop path that is substantially inclined, such that the user's foot motion simulates a climbing motion more than a flat walking or running motion. The reciprocating hand members may be configured to move in coordination with the foot members via a linkage operatively coupling the hand members with the foot members. A resistance mechanism may apply resistance to crankshaft rotation, and the resistance mechanism may be adjustable while the user is using the machine.

A controlled stimulation device used either alone or in conjunction with a treatment device to reduce amount of pain a patient may experience during a treatment with the treatment device.
