An adjustable resistance apparatus includes features that protect a user from harmful heat generated during use while offering a wide range of resistances. The apparatus may be combined with a variety of accessories, such as a load cell.

A portable exercise device that may be arranged in a number of different orientations and positions on the body of an individual. The portable exercise device includes a resistance assembly that enables a resistance of the portable exercise device to be adjusted.

A combination exercise assembly for performing aerobic and strength training exercises includes a base, which can be positioned on a substantially horizontal surface. A stationary bicycle is engaged to the base so that a user positioned on a seat of the stationary bicycle faces a first end of the base. A lat pulldown machine engaged to the base proximate to a second end of the base is positioned for engagement by the user positioned on the seat of the stationary bicycle. The stationary bicycle is pedaled to perform aerobic exercise and the lat pulldown machine resists a pulldown motion to perform strength training exercises.

Disclosed is a machine that functions by a human subject standing on a stationary base with one foot on the base and the other foot on a pedal. The foot on the pedal is positioned such that the hip and knee joints are in the flexed position. On command, the human subject will force the flexed hip and knee joints to full extension. The full extension is followed by relaxation of the engaged muscles allowing the elastic bands to force the hip and knee joints back to the flex position (or starting position). This action is repeated for as many times as is possible within a given period of time. Upright bars (support structure) allow the individual to stabilize themselves during the action. Adjustments can be made to the pedal height of the machine in order to allow proper training for human subjects who differ in height.

An exercise machine that includes a baseplate, pneumatic cylinder assemblies pivotally mounted on the right and left sides of the baseplate, and an exercise bar coupled to the pneumatic cylinder assemblies at each end. A bench assembly is positioned between the pneumatic cylinder assemblies. A support member is removably coupled to the baseplate and the bench assembly.

The present disclosure relates to a stationary exercise apparatus for indoor cycle training (1), i.e. a stationary exercise bicycle, preferably provided with a magnetic resistance unit (15). One embodiment relates to a stationary exercise bike comprising a flywheel (10) defining a radial gap (25) in the periphery wherein at least the periphery of the flywheel (10) has ferromagnetic properties, and wherein a magnetic resistance unit (15) is configured to controllably insert one, two or more magnets into said radial gap.

Systems and methods are presented for performing exercises to strengthen, e.g., the transversus abdominis and related muscles. The systems and methods may involve one or more independent belts, allowing a full range of continuous motion. The systems and methods may further use a resistance-control mechanism that allows a user to adjust the force required to move the one or more belts, thereby controlling the rate of motion in the forward and/or backward directions. The systems and methods may further use a unidirectional resistance mechanism that allows the user to increase the resistance of the one or more belts in one direction, while allowing the one or more belts to move freely in the other direction.

A respiratory treatment device includes a housing, an inlet configured to receive air into the housing, an outlet configured to permit air to exit the housing, and a flow path defined between the inlet and the outlet. A restrictor member positioned along the flow path that is configured to move between a closed position, where the flow of air along the flow path is restricted, and an open position, where the flow of air along the flow path is less restricted. A vane in communication with the flow path rotatable in response to the flow of air along the flow path is configured to move the restrictor member between the closed position and the open position. A protrusion extends in to the housing to limit movement of the restrictor member from the closed position to the open position.

The present invention relates to selectively adjustable speed and incline levels for treadmills. An example treadmill includes a platform around which a belt rotates, a drive motor for controlling a speed of rotation of the belt, a linear motor for controlling an incline of the platform, a human machine interface configured to receive from a user a first selection regarding at least one of the speed of rotation of the belt and the incline of the platform, at least one manual lever configured to receive from the user a second selection to respectively refine the first selection, and at least one controller that selectively changes the speed of rotation of the belt or the incline of the platform based on the first selection received by the human machine interface, and selectively and respectively refines the first selection based on the second selection received by the at least one manual lever.

In one example, a muscle exercise device includes a first arm and a second arm rotatably connected to the first arm, and the second arm and the first arm are configured to cooperatively define a recess having a shape that changes as one of the first arm and the second arm moves toward, or away from, the other of the first arm and the second arm. The muscle exercise device further includes a resistance element configured to reside in the recess and be compressed between the first arm and the second arm so as to assume a configuration similar to the shape of the recess. Finally, a wireless transmitter chip is disposed in either the first arm or the second arm, and the wireless transmitter chip is responsive to communications from an app residing on a user device.
