A rehabilitation therapy aid (FIG. 4), for use in aiding a patient to regain and improve movement and control in a limb, comprises a moveable structure (51) having engagement means (53) whereby the structure can be moved by the limb of a patient (72) requiring therapy and separate engagement means (52) whereby the structure can be moved in the same direction by a therapist (71) or by the patient's stronger limb. A movement detector (56) is arranged so that the movement of the structure (51) can be tracked by the patient and/or by the therapist.

A resistance band exercise machine for performing various exercises. An embodiment includes a housing for a cable-pulley variable resistance system. The cable-pulley variable resistance system is configured to receive one or more safety bars to set a starting position of an exercise. Some embodiments include a training partner assistantship feature for a training partner to assist the user by imparting a secondary force on the machine. The configuration of the cable-pulley variable resistance system may be in any manner based on the exercise. A user performs an exercise on the resistance band exercise machine to overcome a primary (resistance band) and secondary (springs) sources of variably increasing resistance from the cable-pulley variable resistance system.

Connecting straps, for use for example in sports activities, include (a) a sleeve of webbing having a first end and a second end and having a loop at each end, each loop having a base and a free end, (b) disposed within the sleeve of webbing, a band of elastic material extending in a continuous loop, and (c) an attachment strap, adjacent each loop, configured to secure a portion of the band to the webbing at the base of each loop. In some cases, the band has a solid, polygonal cross-sectional shape.

A report of a state of a local exercise device based at least in part on a user response to an electromagnetic resistance unit in the local exercise device is sent. An update based on a state of a remote exercise device is received. The electromagnetic resistance unit is caused to change state in reaction to the received update.

A resistance training system includes a tackle providing mechanical advantage, and a user performs strength training exercises by pulling or pushing on the running block while resisting motion of the running block by pulling or pushing on the free end of the runner. The running block, fixed block and free end of the system may be secured at various locations of the body.

An exercise device includes a shuttle configured to translate along a first and a second cable in response to a separation of the cables by a user. The cables may extend along first and second cable slots that extend through a shuttle housing between first and second sides of the housing. First and second pulleys may be rotatably mounted to the housing and include corresponding first and second engagement surfaces configured to engage respective the first and second cables within the respective first and second cable slots. Separation of the cable ends, proximate to the first side of the housing, relative to the first and second cable slots drives rotation of the pulleys and corresponding translation of the shuttle along the cables, away from the separating cable ends.
