In an example, a bed exercise system is described. The bed exercise system includes a foot pad, a first elastic connector having a first end coupled to a first lateral side of the foot pad and a second end, and a second elastic connector having a first end coupled to a second lateral side of the foot pad and a second end. The bed exercise system also includes an anchor coupled to the second end of the first elastic connector and the second end of the second elastic connector. The anchor is configured to fasten, at a fixed position relative to a bed, the second end of the first elastic connector and the second end of the second elastic connector while (i) the foot pad is moved between a first position and a second position relative to a bed, and (ii) a tension on the first elastic connector and a tension on the second elastic connector increases as the foot pad moves from the first position to the second position.

A lightweight, portable leg strengthening apparatus includes a footplate and calf support which form a leg rest, a top a friction free sliding element running longitudinally along and supported on a rectangular base. The leg rest is hinged at its attachment to the sliding element to allow a longitudinal tilting movement. The leg rest has adjustability at the hinge point at the ankle to enable alterations in the foot position. The apparatus uses resistance material/rubber cords or springs attached via a plate to a steel cable, travelling via an aperture in the end of the device to the back of the sliding element a top the body of the device to create tension as the leg rest a top the sliding element is moved longitudinally along the body of the device. Resistance can be varied and progressed by using different numbers of resistance cords/springs.

An exercise device includes a base member configured for engaging a mounting structure including a first surface and an oppositely arranged second surface. The first surface of the mounting structure faces towards the user and the second surface of the mounting structure is configured to engage the base member. A coupling system of the exercise device couples the base member to the mounting structure. An arm is pivotally coupled to the base member and is configured to pivot between a retracted position and an operational position. A resistance member is directly coupled to the arm and includes a control member configured to be manipulated by a portion of the user.

Embodiments of the present invention comprise a portable exercise platform allowing users to exercise on a soft substrate. The portable exercise platform comprises at least three panels wherein the at least three panels are connected by at least one hinging device allowing the at least three panels to lay flat or fold into proximity to each other. The at least three panels are configured with a top surface and bottom surface such that the top surface is configured to support a user and the bottom surface is configured to contact the soft substrate when the portable exercise platform is lying flat.

A portable exercise device includes a pedal spaced away from and pivotably connected to a base and having a neutral position relative to a pivot axis. The pedal is configured to rotate about the pivot axis in a first direction toward the base and in a second direction, opposite the first direction, toward the base. The device also includes a resistance mechanism configured to exert a force on the pedal about the pivot axis in a direction opposite to the respective direction of rotation of the pedal. The device is movable between an open, in-use configuration, where the pedal is disposed in the neutral position to receive a foot and spaced away from the base, and a closed configuration, where the pedal is adjacent the base.

In an example, a bed exercise system includes a foot pad and first and second elastic connectors. The foot pad includes a rigid support member. The first elastic connector has a first end coupled to a first lateral side of the foot pad and a second end for coupling to a support structure. The second elastic connector has a first end coupled to a second lateral side of the foot pad and a second end coupling to the support structure. When the second ends of the first and second elastic connectors are coupled to the support structure: (i) the foot pad is movable between a first position and a second position relative to the support structure, and (ii) a tension on the first elastic connector and a tension on the second elastic connector increases as the foot pad moves from the first position to the second position.

A mounting frame for releasably securing a pedal exerciser to a table is disclosed. The mounting frame includes a frame assembly having a pair of generally opposed end members dimensioned to extend across an upper surface of the table and configured to receive feet of the pedal exerciser, and a pair of generally opposed side members connected to the pair of generally opposed end members at corresponding ends thereof, so as to cooperatively define a central aperture therewith with the pair of generally opposed side members configured to engage opposite sides of the table. The frame assembly further includes a first strap dimensioned to extend across the central aperture and engage the pair of generally opposed side members so as to releasably secure the table therebetween.

Methods for treating fluid overload in a subject comprise shifting fluids directly and non-invasively from an interstitial compartment of the subject to skin of the subject through controlled local sweating. Methods of the invention allow for removal of excess fluid from the interstitial compartment of the subject and treat fluid overload in the subject. Sweat stimulation systems comprise a chamber and first and second relative humidity sensors. The chamber is sized to fit around a body part of a subject, comprises an inlet and an outlet, and is configured such that air flows through the chamber from the inlet to the outlet. The first relative humidity sensor is operably located inside the inlet, and the second relative humidity sensor is operably located proximate the outlet.
