A device for rehabilitating or strengthening the ankle includes a plank that is connected by a transversely oriented hinge and a longitudinally oriented pivot, as well as a pair of compression springs at its forward end. The connections of the plank to the underlying base limit the plank to motion in two directions about two axes, thereby providing four types of therapeutic ranges of motion, including dorsiflexion and plantar flexion, eversion and inversion. A transversely slidable foot rest enables the user to hold device 21 in position with one foot while using the plank of the device to rehabilitate the other foot.

The present invention is an adjustable leg exercise apparatus for allowing a user to perform a leg exercise while sitting on a sitting structure, or alternatively, when standing in a modified standing position. In a first embodiment, the adjustable leg exercise apparatus includes a foot engagement member; a knee-thigh engagement member; at least one elastic resistance member; at least one foot securing mechanism for securing or locking the foot engagement member to the at least one elastic resistance member; at least one knee-thigh securing mechanism for securing or locking the knee-thigh engagement member to the at least one elastic resistance member; and a plurality of length adjustment and securing devices for securing each of the at least one elastic resistance member in any one of a plurality of predetermined adjustment positions. In a second embodiment, the knee-thigh engagement member may include a knee-thigh wrapping device.

An exercise step and method of exercising a user's legs is disclosed. The exercise step includes a main body which has a substantially planar and horizontally oriented upper wall and a sloped wall extending from bottommost surface of the exercise step to the upper wall. In use, a user steps on the sloped wall with a heel portion of his or her foot and raises the heel portion such that a sole portion of his or her foot is supported by the upper wall.

A resistance system, which can be suitable for incorporation in exercise equipment, is a hybrid resistance assembly having at least a first and a second resistance unit. The first resistance unit can be of a first type and the second resistance unit can be of a second type. The first resistance unit can be an inertial resistance unit, which incorporates an inertial load that creates resistance influenced by the inertia of a movable mass, such as a rotatable flywheel. The second resistance unit can be a static or non-inertial resistance unit, such as a displacement resistance unit, which incorporates a load that creates resistance influenced by displacement (e.g., linear or rotational displacement) of an input to the displacement resistance unit.

A calf exercising assembly for performing seated calf exercises includes a pair of blocks that is each selectively positioned on support surface thereby facilitating a user's feet to be positioned thereon. Each of the blocks spaces the user's heel from the support surface thereby facilitating the user to perform seated calf exercises. A yoke is provided and the yoke is coupled to a weight. Additionally, the yoke is positioned on the user's thighs thereby facilitating the user to perform seated calf raises.

A structure including left and right footplates and weight shafts provided at left and right sides in a blood circulation exercise interlocking device, providing a pelvic limb blood circulation ankle interlocking device comprising a vertical supporter configured at the center of a lower plate of a main body in a vertical direction, left and right auxiliary vertical supporters configured to be parallel in a vertical direction at left and right sides of the vertical supporter, rotary shafts configured at the same position as the left and right auxiliary vertical supporters in a horizontal direction of the vertical supporter, left and right rotary bars configured at left and right sides of the rotary shaft to be coupled with a rotating device, weights made of heavy metals at the upper ends of the left and right rotary bars, and left and right footplates configured at left and right rotation lower ends.

According to the invention, there is provided an exerciser suitable for exercising lower leg muscles wherein the exerciser comprises a support and a two part foot platform wherein each part of the foot platform is rotatable such that a first part of the foot platform allows plantar flexion rotational movement of a foot and that a second part of the foot platform allows dorsiflexion rotational movement of the foot; and a dual foot exerciser wherein the respective first parts of each foot platform are connected together and/or the respective second parts of each foot platform are connected together such that movement of a first or second part on one exerciser moves the corresponding first or second part of the other exerciser; by separating the movement of the foot by the provision of a two part rotatable foot platform, the exerciser allows natural movement of the foot, ankle and lower leg; with the optional addition of a resilient member of variable resistance for muscle strengthening and/or a mechanical device to move each of the foot-plates individually or in sequence, to provide plantar and dorsi flexion where voluntary movement is affected such as in MS or foot drop from stroke.

A resistance system, which can be suitable for incorporation in exercise equipment, is a hybrid resistance assembly having at least a first and a second resistance unit. The first resistance unit can be of a first type and the second resistance unit can be of a second type. The first resistance unit can be an inertial resistance unit, which incorporates an inertial load that creates resistance influenced by the inertia of a movable mass, such as a rotatable flywheel. The second resistance unit can be a static or non-inertial resistance unit, such as a displacement resistance unit, which incorporates a load that creates resistance influenced by displacement (e.g., linear or rotational displacement) of an input to the displacement resistance unit.

A work platform has a top member with a surface sized to receive a user's feet thereon while standing and a bottom member coupled to the top member. The bottom member has a width and length generally equal to the width and length of the top member. The bottom member has a curved surface generally at the longitudinal center of the work platform defined at least partially by a radius of curvature of between about 100 mm and about 850 mm. The curved surface induces instability under a user standing on the top member to thereby facilitate active muscle engagement in the user's legs while standing on the work platform.

A leg exercise assembly includes a panel that is laid on a horizontal support surface. The panel has a prominence extending upwardly therefrom and the prominence is selectively stood upon with toes thereby facilitating calf raises to be performed. The prominence is selectively stood upon with a heel thereby facilitating toe raises to be performed. A plurality of hooks is coupled to and extends upwardly from the panel. A pair of plates is provided and each of the plates is selectively positioned on the prominence to adjust a height of the prominence. A pair of straps is coupled to the panel and each of the straps engages the toes when the prominence is stood upon with the heel. Each of the straps is comprised of a resiliently stretchable material to exercise shin muscles when the toe raises are performed.
