An exercise device is provided with a first element disposed at a first side and a second element disposed at a second side. The first element includes gripping features to prevent skidding or sliding of exercise device when first element is abutting a surface. The second element includes sliding features to facilitate sliding of exercise device when second element is abutting the surface. Thus, when an exercise practitioner desires to use the exercise device to prevent movement of a particular body part against the surface, the practitioner places the first element against the surface. Conversely, when the exercise practitioner desires to use the exercise device to facilitate movement of a particular body part against the surface, the practitioner places the second element against the surface. The exercise device further includes an insert which may be removed and heated or cooled to provide heating or cooling pad/pack to a body part.

A workout device that allows for at home Nordic hamstring curls using a. doorframe or other immovable object is disclosed.

An exercise machine handle system which provides for a plurality of exerciser positioning surfaces and gripping handles. The exercise machine handle system generally includes an exercise machine carriage and end platform handle system. The exercise machine carriage and end platform handle system includes a plurality of gripping features, thus allowing the exerciser to perform a substantially expanded repertoire of exercises using the exercise machine handle system. An exemplary embodiment of an exercise machine carriage and end platform system may include a carriage with a plurality of handles and a plurality of intermediate support members. In another exemplary embodiment, an exercise machine carriage and end platform system may include an end platform with a plurality of handles, a split carriage, and/or ladder step handles on a handle assembly.

A track exercise device with at least first and second substantially parallel tracks, and first, second, third, and fourth movable platforms. The first and third movable platforms are movable on the first track, and the second and fourth movable platforms are movable on the second track. Transverse attachments selectively and respectively attach the first and second movable platforms together on the first and second tracks and the third and fourth movable platforms together on the first and second tracks. Longitudinal attachments selectively and respectively attach the first and third movable platforms together on the first track and the second and fourth movable platforms together on the second track. A tilting adjustment selectively provides for inclined or flat movement of the first, second, third, and fourth movable platforms.

The exercise machine handle system generally includes an exercise machine carriage and end platform handle system. The exercise machine carriage and end platform handle system includes a plurality of gripping features, thus allowing the exerciser to perform a substantially expanded repertoire of exercises using the exercise machine handle system. An exemplary embodiment of an exercise machine carriage and end platform system may include a carriage with a plurality of handles and a plurality of intermediate support members. In another exemplary embodiment, an exercise machine carriage and end platform system may include an end platform with a plurality of handles, a split carriage, and/or ladder step handles on a handle assembly.

A computing system for determining osteogenic loading from an exercise apparatus for performing an exercise is provided. The exercise apparatus includes a loading interface, a frame, a linear adjustment system interposing between and fixedly coupled to the loading interface and the frame, and a sensor coupled to the linear adjustment system. A position of the loading interface of the exercise apparatus is adjusted through a movement of the linear adjustment system at one or more intermediate positions of a plurality of functional positions of the loading interface. A force exerted by a subject on the loading interface at the position in the one or more intermediate positions is received. A measurement of the force exerted by the subject on the loading interface at the position in the one or more intermediate positions from the sensor is obtained. A corresponding osteogenic loading for the force exerted by the subject is determined.

A device for an exercise apparatus includes a linear adjustment system and a sensor coupled to the linear adjustment system. The exercise apparatus includes a loading interface and a frame coupled to the loading interface for performing an exercise. The linear adjustment system fixes the loading interface of the exercise apparatus at any one of a plurality of functional positions in a functional range of the loading interface. The sensor measures the force exerted on the linear adjustment system. A correlating mechanism is used to correlate the force exerted on the linear adjustment system with the force exerted on the loading interface. The device allows exercisers to exert high or maximum loads in any one of a plurality of positions throughout their entire range of motion without first passing through a weak range of motion.

An exercise machine support system for providing increased versatility including inclination or declination of an exercise surface, a reduction in the overall length and width of the exercise machine, and an enhanced user interface which reduces the risk of injury. The exercise machine support system generally includes a cantilevered exercise machine which is adapted to have a variable angle of incline or decline with respect to a horizontal ground surface. The exercise machine will generally include a base and a support which extends between the base and the exercise machine. The upper end of the support is connected to the exercise machine by a first pivot such that the exercise machine pivots about the support. An adjustment device may be utilized to pivot the exercise machine and thus adjust its angle of incline. Various types of adjustment devices are disclosed, including an actuator, ratchet-and-pawl, gears, and cam.

An exercise machine handle system which provides for a plurality of exerciser positioning surfaces and gripping handles. The exercise machine handle system generally includes an exercise machine carriage and end platform handle system. The exercise machine carriage and end platform handle system includes a plurality of gripping features, thus allowing the exerciser to perform a substantially expanded repertoire of exercises using the exercise machine handle system. An exemplary embodiment of an exercise machine carriage and end platform system may include a carriage with a plurality of handles and a plurality of intermediate support members. In another exemplary embodiment, an exercise machine carriage and end platform system may include an end platform with a plurality of handles, a split carriage, and/or ladder step handles on a handle assembly.

A multipurpose exercise device is provided. The device includes features which allow the device to exhibit self-stabilizing features. The device includes a weighted body characterized by at least three substantially-loop-shaped handles which have dimensions and arrangements that are effective to cooperatively urge the device into one of several predetermined self-stabilizing rest positions. The rest positions are characterized by engagement portions of two of the provided handles resting against a support surface, while an elongated device bore extending along a center axis of the device is maintained in a substantially-horizontal orientation. The device may be stored safely in a variety of arrangements, including on a rack typically used for dumbbell storage.
