A rehabilitative and/or exercise machine that has a frame with attachments to multiple independent bidirectional resistance devices (pneumatic, hydraulic, spring actuated, pulley system, cam, or any other resistance devices) used by the arms and/or legs to provide resistance against movement of the user's appendages in two substantially opposed directions. The resistance devices may have a mechanism such as one or more valves, brakes, springs, or the like that control bi-directional resistance. The action of the arms and/or legs in bi-directional resistance offers near full body exercise of the agonist/antagonist muscles using flexion and extension action of the larger muscle groups in a gait pattern, simultaneously. Hand engaging members attach to the arm resistance devices and foot engaging members attach to the leg resistance devices. The unit may include an attached inclined backboard, mat, bench, or cushion to fully or partially support the user, such as for the user to sit or lay on. The unit may have separate adjustment mechanisms for adjusting the height and/or length of the various portions of the unit to adjust the range of motion of the appendages. The unit may have devices to monitor pulse, oxygen flow and other vital signs.

A plural parallel cuff for muscle training is made to reinforce muscles of limbs while it is wound broad around the portion of an upper arm and/or a thigh with uniform and stable binding force for the light exercise training. Three cloth sleeve bags are sewn to a connection cloth spaced in parallel. Three short rubber bags are inserted into three cloth sleeve bags respectively. The rubber bags are connected each other with T-joints for air channel. A plug and a socket are used to connect the pneumatic pump detachably to the thin tube. The plural parallel cuff is wound around a limb and hook-and-loop fasteners are used to form loops by uniting both ends of each of the cloth sleeve bags. The rubber bags are inflated by a pneumatic pump for restricting the bloodstream and then an low intensity exercise is performed.

The invention describes a method and apparatus for plyometric force application to muscle with a plyometric force application element for controlling the amount of plyometric force application. Plyometric force profile and temporal variability, plyometric force intensity, control, and force direction on a 360 plane, can be applied with 360 degrees of vector possibilities of 3-dimentional space, and control of other plyometric force factors for muscle activation of muscle or a group of muscles.

An underwater striking bag device includes a bag having an annular upper compartment disposed in an upper section of the bag and receiving air therein, a neck extending through the upper section and communicating with a lower compartment receiving water therein, a removable cap connected to the neck, an air valve connected to the annular upper compartment to provide for filling air into said upper compartment, at least one handle connected to the bag for assisting in filling and removal of water into the lower water compartment.

The present invention relates to a comprehensive fitness equipment leg press that allows a user to do a weight training leg press exercise for training a lower body of the user by the user sitting on a bench and pushing a footrest included in a footrest frame, which moves back and forth smoothly along a central frame for adjusting a weight of the footrest frame. The comprehensive fitness equipment leg press includes a weight adjusting unit from 10 kg to 200 kg through a hydraulic cylinder formed on a lower end of the bench, without using 15 10 kg weights, and a hydraulic cylinder rod connection installed on a body of a weight adjusting bar using a principle of a lever for adjusting the weight of the footrest of the footrest frame.

An exercising device for strengthening of abdominal muscles with a frame having a resistance mechanism, the device including an inclined bench (3) associated with the press arm (4) connected to the resistance mechanism (9) creating resistance force only in one direction, whereas the press arm (4) is pivotally mounted at one end and its other end is positioned above the inclined bench (3), and is provided with means (8) for pushing and/or holding by user's hands.

An exercise treadmill is disclosed. The treadmill can include one or more sensors to acquire input data. A computer system can trigger one or more actions based on the input data. The input data can correspond to a lengthwise position of the user along a length of a usable surface of the platform and/or a lateral position of the user on the belt. The action(s) can include providing feedback to the user and/or adjusting rotation of the belt and/or a resistance of rotation of the belt. The adjustment can be performed in response to input from a user control requesting the adjustment.
