A balance board system, comprising, a rotatable roller, a balance board having a lower surface that sits atop the rotatable roller and reciprocally rides on the rotatable roller, the balance board lower surface having a plurality of attachment points, a plurality of board connectors disposed at the plurality of attachment points, a plurality of stop connectors and a plurality of roller stops coupled to at least two of the plurality of stop connectors, the plurality of roller stops are attachable to the balance board at a respective one of the plurality of attachment points.

The present invention includes an arm; a leg pad; a long rectangle shaped seat; a seat angle fixing unit on the seat, for adjusting the angle between the seat and the leg pad (when viewed from above) according to his/her purpose so that the seat can be adjusted to be perpendicular or parallel to the leg pad when viewed from above; and thus the to the user is allowed to move the exercising leg of the user to the back of the user or perform a motion for stretching his/her back straight from a starting pose at which the user lie down on his/her back placed on the seat, wherein the leg pad is placed above the user's pelvis.

An exercise apparatus having an upper body portion and a lower body portion, the upper and lower body portions positionable in a substantially horizontal position to accommodate a user in a kneeling position. A connector connects the upper and lower body portions. First and second resistant members are attached to the one or both of the upper and lower body portions. The body portions can be movable between a closed folded position and an open position.

An exercise bike operable while remaining stationary on a support surface. The exercise bike includes a bicycle frame with a pedal assembly coupled to a clutch mechanism that is movable between an unlocked state in which the pedal assembly drives a wheel in a first rotational direction and rotates relative to the wheel in a second rotational direction, and a locked state in which the pedal assembly is rotationally fixed to the wheel to drive the wheel in the first rotational direction and the second rotational direction, and a handlebar assembly. The handlebar assembly is coupled to the bicycle frame and includes a handlebar and a locking mechanism. The locking mechanism is moveable between an unlocked position in which the handlebar is allowed to rotate about an axis, and a locked position in which the handlebar is restricted from rotating about the axis. A control module may move the locking mechanism and the clutch mechanism between their respective locked and unlocked states.

A spring exercise system and method of exercising that allows a user to perform a full body, low-impact style of exercise. The system utilizes a non-fixed extension spring that stretches and generates resistance when pulling and pressing forces are applied. The extension spring or springs are stretchable between multiple types of interchangeable grasp handles which may include any combination of a resilient loop handle with or without double “D” rings, a single rigid handle, and/or a resilient double loop handle. The spring may have a swiveling link or other mechanism/structure that joins the free ends of the spring to the grasp handles allowing a 360° rotation. The grasp handles are used with combinations of hands and feet, arms and legs to generate an extension of resistance that stretches, strengthens and tones muscles, enhances flexibility, core strength, joint stability, and muscle balance.

Exemplary arrangements provide leg training devices suitable for high intensity training of hip flexors while simultaneously training the extensors of hip and knee joints. The exemplary leg training devices include foot fixings which are permanent vertically movable components of the device, each of which are configured to releasably engage a foot of a user in operative engagement therewith while limiting the movement of the foot relative to the foot fixings. Each of the foot fixings is operatively connected to a suitable mechanism that provides a resistance force to vertical movement of the foot fixing by the user's leg. In exemplary arrangements the resistance force may be selectively variable with regard to the magnitude and/or point of application so as to provide the desired training regimen.

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.

An exercise system includes a base module having a seat with a seat depth, and a vertically adjustable back configured to fixedly engage with the base module at a first seat depth and a second seat depth different from the first seat depth.

A resistance device capable linearly adjusting training load comprising: a rack unit with two vertical rods, and two sliding units, which are connected to a handle and a pedal; a linkage unit with a chain and a belt, and are locked on the connecting plate; and two damping units make multiple magnet pieces arranged on both sides of a fixing base, and a diamagnetic metal piece is arranged on the connecting plate, and set trough the fixing base to cut the magnetic circuit generated by the magnet pieces to form damping: When the user steps on the pedal, the connecting plate will drive the metal sheet to cut the magnetic circuit, and the damping can be changed to further achieve the effect of linearly adjusting the training load.

A leg exercise assembly includes a housing that is positionable near a user's feet. A pair of foot pads is each disposed on the housing for having a respective one of the user's feet positioned upon the foot pads. A pair of roller units is each rollably integrated into the housing and each of the foot pads is coupled to a respective one of the pair of roller units for sliding the foot pads back and forth on the housing. A resistance unit is movably integrated into the housing for either increasing or decreasing the force required to move the footpads to accommodate the physical strength of the user. A calorie counter is integrated into the housing and the calorie counter counts each time the pair of roller units is moved back and forth to calculate the calories being burnt by the user.
