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 machine can include a frame, one or more platform arms that can be driven by a motor or a hydraulic system, and one or more handle arms that can be grasped by the user's hands. The exercise machine can guide the user through movement that actively flexes and extends portions of a user's body while the user exercises to provide, for example, dynamic stretching and cardio benefits while achieving strength training.

An exercise machine for a near-elliptical arm movement, comprising at least one manual arm-moving structure system enabling an elliptical movement pivotably connected to a cycling pivot shaft structure at one position thereof, and performs a circular movement, elliptical movement, near-elliptical movement, or unidirectional full-cycle movement; and pivotably connected to a reciprocating pivot shaft structure at another position thereof, or performs a linear or curved bidirectional reciprocating movements under restriction and control of a related guide wheel structure system or guide rail structure system. Other portions of the manual arm-moving structure enabling the elliptical movement perform a near-elliptical movement under the collective action of systems related to the full-cycle movement or the bidirectional reciprocating movement. An arm of a user is also moved in a near-elliptical trajectory by means of a corresponding handle structure directly or indirectly provided on the manual arm-moving structure enabling the elliptical movement.

An exercise machine may include a reciprocating linkage that supports one or more pedals configured to move in a closed loop (e.g., elliptical) path as a user exercises with the machine. The exercise machine may be adjustable to vary a characteristic of the exercise provided by the machine, for example by changing an incline of a rail supporting the reciprocating linkage, and thus an angle of the closed loop path. The exercise machine may vary the incline with a lift mechanism operatively associated with the front upright frame of the machine, which may also support a resistance assembly, all in a compact form factor that may be more aesthetically pleasing and practical for relatively smaller exercise spaces.

An exercise machine is for performing a striding exercise motion. The exercise machine has frame; first and second pedal members; first and second foot pads on the first and second pedal members, respectively, each of the first and second foot pads being configured to move in an elliptical path during the striding exercise motion; first and second rocker arms pivotally coupled to the frame; and first and second adjustment devices configured to actively adjust and set a position of the first and second pedal members relative to the first and second rocker arms, respectively, which thereby changes a shape of the elliptical path.

A running emulator for increasing an athlete's strength in the movement of specific muscles used for running includes: a lower body frame; a pair of leg assemblies movably mounted on the lower body frame and having a leg extension carrier, a leg extension member slidably mounted through the leg extension carrier, a foot cradle mounted to the leg extension member; and two leg resistance members located on an outside of the lower body frame and connected to each of the pair of leg assemblies for resisting pivoting of the leg extension carrier relative to the lower body frame. During use by an athlete, the leg assemblies pivot and the leg extension member reciprocates through the leg extension carrier such that a path travelled by the athlete's foot on the foot cradle emulates motion of a sprinter.

An overhead climb strength trainer apparatus comprises a frame bisected by at least one vertical frame portion, forming first and second climbing areas. First and second climbing panels are slideably mounted within the respective climbing areas and each include climbing holds and a panel hook. A line connects the first and second panel hooks, running through line guides and around a friction cylinder. The frame is configured for mounting at a predetermined angle of inversion for simulating an overhead climb as users manually raise and lower the first and second climbing panels in a reciprocating fashion within the first and second climbing areas respectively.

An exercise machine may be adjustable to vary a characteristic of the exercise provided by the machine, for example by changing the reciprocation path of movable components of the machine. In some examples, adjustment to an incline of the path of a reciprocating linkage may be achieved, for example by a lift assembly, the components of which may be arranged in a manner that provides a relatively compact form factor. In general, a more compact design may be achieved through the examples of the present disclosure, for example by co-axially locating a rotatable resistance element on the driven/input shaft.

An exercise machine is for performing a striding exercise motion. The exercise machine has a frame; first and second pedal members; first and second foot pads on the first and second pedal members, respectively, each of the first and second foot pads being movable along an elliptical path during said striding exercise motion; and first and second rocker arms each having a first end that is pivotable with respect to the frame about a rocker arm pivot axis and further having a second end that is pivotable with respect to one of the first and second pedal members about a pedal lever hub axis. The frame has first and second frame portions. The first frame portion supports the first and second rocker arms and is pivotable about a frame pivot axis relative to the second frame portion. Pivoting the first frame portion relative to the second frame portion adjusts a position of the rocker arm pivot axis, which thereby changes a shape of the elliptical path.

The function of this invention is to provide exercisers with a safe and easy way to convert a legs-only exercising device, such as a stationary trainer or bicycle, with the capacity to exercise their upper and lower body muscle groups simultaneously or separately. This invention is portable and can be moved easily from one legs-only exercising device to another. Once they are mounted onto the handlebar or attachment bar of the legs-only device, it is now a full-body trainer. Exercisers mount the trainer, place their feet on the cycling pedals, place their elbows onto the elbow holders, grasp the hand grips, and now start their full body exercising activity. The degree of difficulty of their exercise trek is easily accommodated by allowing the rider to adjust the resistance for moving the forearm bars up and down for an upright bike, or back and forth for a recumbent trainer.
