A method for exercising muscles in an ankle, foot, and/or leg of a user includes positioning a foot of a user onto a first body of an exercise device. The first body is spaced away from a second body of the device and pivotably connected to the second body of the device at a pivot axis. The pivot axis is adjacent to a central portion of the first body. The method includes rotating the first body about the pivot axis, with the foot, against a first resistive force. Rotating the first body includes subjecting the foot to a first motion. The method includes positioning the foot onto the second body. The method includes rotating the second body about the pivot axis, with the foot, against a second resistive force. Rotating the second body includes subjecting the foot to a second motion, the second motion being different than the first motion.

A stretching device includes a heel platform sized and shaped to support a heel of a foot of a person thereon. The stretching device also includes a ball platform sized and shaped to support a ball of a foot of a person thereon. The ball platform is angularly offset relative to the heel platform. The stretching device includes one or more connection members connecting the heel platform to the ball platform. The stretching device includes an extension slot connected to the ball platform. The stretching device includes a stretching device extension. The stretching device extension includes an extension platform arranged coplanar with the ball platform. The stretching device extension includes an extension insert arranged within and selectively removable from the extension slot.

The present invention relates to a pressure-measuring foot hoard having a sturdy structure which may be used in an exercise apparatus capable of precisely measuring and correcting the state of imbalance of the body of a user, and to an exercise apparatus for correcting the state of imbalance of the body comprising the pressure-measuring foot board. The pressure-measuring foot board according to the present invention may firmly fix a pressure-measuring element for measuring the state of imbalance of the body of a user while also preventing or minimizing damage to the elements of the foot board, including the pressure-measuring element, when the foot board is being tilted for balancing exercises. Moreover, an exercise apparatus for correcting the state of imbalance of the body may be provided which can, by means of the pressure-measuring foot board, precisely measure the state of imbalance of the body, and, on the basis thereof, provide corrective exercises that are suitable for the amount of imbalance of each individual's body.

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.

A sliding balance board has an eccentrically mounted center wheel as a pivotable central balancing member, a wheel with one-way sprag clutch bearings mounted near the left end of the board and a wheel with one-way sprag clutch bearings mounted near the right end of the board. A user balances himself/herself on the board, and yet slides the board to the left and right, back and forth by shifting his/her weight left and right, synchronized to the rocking motion of the eccentrically mounted center wheel.

An exercise device is described. An exercise device including a body, the body having a top, a bottom, a first end located at one edge of the body, a second end located at an opposite end of the body, and first and second sides extending between the first and second ends; one or more wheels; and an energy storage device applying resistive and restoring force to the wheel. Optionally, a shaft can be present that rotationally locks two or more of the wheels.

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.
