In one example, a muscle exercise device includes a first arm, a second arm rotatably connected to the first arm, and the second arm and first arm configured to cooperatively define a recess. The muscle exercise device also includes a resistance element configured to reside in the recess and be compressed between the first arm and the second arm, and a wireless transmitter disposed in either the first arm or the second arm, wherein the wireless transmitter is responsive to communications from an app residing on a user device.

A multifunctional mobile exercise apparatus and method for exercising the upper extremities is disclosed. The apparatus includes a base, an elongate shaft pivotally coupled to the base, a plurality of ground lockable ground wheels supporting the base. The apparatus includes a resistance clip that is selectively positionable along a length of the elongate shaft. A cylindrical sleeve may also be provided for sliding, with or without a resistance band, along the length of the elongate shaft. The mobile exercise apparatus provides single or bilateral hold for one or more resistance bands and the mobile arm. The resistance band and the mobile arm can be held by the injured or non-injured extremity. The elongate shaft and locks up to 8 feet high, and can also be used for the attachment jumbo resistance clips, or for the sliding exercises.

An exercise machine resistance adjustment system for providing an exerciser the ability to immediately adjust the resistance force by changing their body position on the movable carriage or end platforms. The exercise machine resistance adjustment system generally includes a frame, a carriage movably positioned on the frame, a spring connected to the carriage to apply a biasing force to the carriage, one or more left projections within the carriage adapted for a left hand of an exerciser to grasp, and one or more right projections within the carriage adapted for a right hand of an exerciser to grasp. The exerciser is able to efficiently adjust the amount of resistance force applied to the carriage by repositioning their hands (or feet) from a first set of projections at a first distance to a second set of projections at a second distance from the first end of the exercise machine.

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.

An exercise device is described which includes a platform having a first end and a second end opposite the first end; first and second wheels, wherein the first wheel is positioned proximate the first end and the second wheel is positioned proximate the second end and the first and second wheels are configured to roll across a surface as the exercise device is displaced along the surface; a first motor configured to apply a first torque to the first wheel where the magnitude of the first torque is related to the distance of the exercise device from a zero position and the direction of the first torque urges movement of the exercise device toward the zero position. Versions are also described with more wheels and more motors.

A multipurpose exercise device for replicating exercise motions that has a base on a support surface and a user platform. One end of a support post is axially mounted to the base and the other end is pivotally mounted to the user platform. The platform pivots with the post in a horizontal plane parallel to the support surface and pivots in a vertical plane perpendicular to the support surface. Resistance elements, dampening elements and a linkage system are selectively mounted to the support post and the base to control the velocity and angle of pivot of the platform in the horizontal and vertical plane. Ski and snowboard modules may be mounted to the user platform. The user stands on the platform or modules and performs exercise motions to propel the platform in the horizontal plane and the vertical plane to replicate the exercise motions, e.g., skiing and snowboarding.

A preloaded resistance pack and exercise device. The resistance pack includes an elastomeric resistance element coupled to a hub and disposed on a plate. The hub includes a pair of radially extending wings that lie against a surface of the plate. The plate includes a pair of raised tabs that lie within a rotational path of the wings. An initial rotation of the hub relative to the plate causes the wings to slide over and beyond the raised tabs and at least partially stretches the resistance element. Interaction between the tabs and wings prevents the hub from rotating back to an initial position and maintains the resistance element in a preloaded, tensioned condition. The exercise device is configured to detect a number of the resistance packs coupled thereto as well as data associated with exercise movements employing the resistance packs.
