pass technique . fig4 shows a top view of a roller board in accordance with an aspect of the present invention . the foot pedal 40 preferably has four wheels 100 and two center mounts 102 . an impression for a foot ( not shown ) can be provided in the top of the roller board . fig5 shows a bottom view of the roller board in accordance with an aspect of the present invention . fig6 and 7 show side views of the roller board in accordance with an aspect of the present invention . as shown , the wheels 100 are attached on the outer edges of the side of the roller board 98 with brackets 110 by bolts or screws 112 . the wheels contact the underside of the horizontal track 96 in the frame and freely rotate to allow the foot pedal to move in the tracks 96 . the center mount 102 has two wheels 114 and 116 which extend downward from the foot pedal to contact the top of the frame . the wheels 100 prevent the foot pedal from moving up off the frame and the wheel 114 and 116 keep the foot pedal in contact with the frame 2 . the wheels 102 attached in the center of the roller board 98 freely roll above the horizontal track 96 . fig8 shows a side view of the assembled training device in accordance with an aspect of the present invention . fig9 shows the apparatus in accordance with an aspect of the present invention in usage . as shown in fig1 , the roller board is held onto the track by the use of wheels , two wheels being on the outside of the roller board and two wheels being on the inside of pedal and generally not immediately visible to the naked eye . the base , roller board and wheels can be made using heavy duty plastic or any other synthetic material suitable for this system . the manner of using the push - pass system is similar to a player passing the ball using his / her own muscle and leg strength . the system , however , will guide the player &# 39 ; s muscles to mimic proper passing technique needed to move the ball from player to player in the appropriate manner . the player will stand next to the machine , intersecting the machine at a right angle . the player will place his or her foot on the roller board , moving his or her foot along the track back and forth along the whole of the track in a horizontal motion , from end to end , thereby mimicking proper push - pass techniques and creating muscle memory each time the machine is utilized . see fig9 . the ankle of the players passing foot should remain locked while the motion is being performed . to help facilitate this , the toes should be curled up and the shin muscle should be flexed . the knees of the player should be bent slightly in order to make the player more stable and perform the motion correctly . fig9 shows a player performing the motion using his right foot to pass and his left foot to remain stationary . the stationary foot is on the ground , flush to the push - pass system , parallel to the motion direction and approximately placed in the center of the system . this is done without a ball being kicked . after the player repeats this motion , the player then practices the motion by kicking a ball with another player . it is believed that a player should repeat the passing motion on the training device 100 to 500 times every practice session and then practice passing with a ball with another player multiple times . preferably , practice sessions occur two to four times a week . it is a primary objective of this embodiment to provide a push - pass technique training system that may rapidly increase a player &# 39 ; s passing skills by providing information as to how the player should stand and position him / herself while passing the ball , in relation to the ball , and to stimulate proper movement and muscle memory in the legs so that the player may utilize these correct muscles and techniques perfectly each and every time s / he passes the ball in a game or practice situation . from the descriptions above , a number of advantages of the push - pass technique system become evident : the player will gain muscle memory as to the proper technique as to how to pass the ball in a proper manner and how to position one &# 39 ; s body when doing so . the portable push - pass technique system can be set up on the field in seconds flat . soccer players can train on the machines and not waste valuable training time waiting in line for drills . soccer players can also use the machine at home as a way to train and learn proper techniques on their own time either inside the home or outside the home . the embodiment of the push - pass technique system provides a versatile , effective and productive soccer training system that can be used by coaches or individual players on soccer fields , parks , indoors or in backyards . the apparatus of the present invention could also be made with a single track . further the foot pedal could be guided in the track with simple pegs that extend downward from the foot pedal into the track . various other alterations to the apparatus can be made while still remaining within the scope of the invention . while the above descriptions contain specific embodiments of the present invention , these should not be construed as limitations on the scope of the invention . although the above described device has two tracks , the device may be built with one or more tracks provided the roller board is only able to move in the above description . the tracks may be made of any lightweight durable material and the wheels or pegs guiding the roller board may be parallel or perpendicular to the track as long as the desired motion is achieved . in accordance with one aspect of the invention , it is preferred that the board not be able to have a rotational pivot as this could cause the player ( s ) to develop bad technique habits . the roller board may have a foot pedal attached and this foot pedal may have adjustable clamps in order to secure the users foot so it cannot slide of the board during use . if there is no foot pedal for the user , the user should be sure to keep his foot perpendicular to the direction of motion . in a further embodiment of the present invention the foot of the user on the board is in a pre - determined angle in relation to the direction of the motion of the leg of the foot . in a preferred embodiment the angle of the foot in relation to the motion of the leg is at an angle of 90 degrees . the foot in a further embodiment of the present invention can also be at a smaller angle in relation to the motion of the leg . a pedal on the board or the entire board , in one embodiment of the present invention , is rotatable in a fixable manner , so that a preferred angle of the foot can be implemented for exercise . this is helpful in situations wherein a player , for instance because of an injury , is not able to turn the foot initially to a complete 90 degrees angle , but still would like to exercise the leg . the board or pedal in one embodiment of the present invention are rotatable to a fixed position , wherein the foot can be placed on the board or pedal at a fixed angle in relation to the movement of the leg that is greater than parallel to the moving direction and not greater than 90 degrees . in yet a further embodiment of the present invention the angle of the foot on the board is equal or greater than 30 degrees in relation to the movement of the leg . the foot on the ground ( the plant foot ) should be parallel lengthwise to the device and should be placed flush to the side of the device and as close the center as possible . for more advanced players , the plant foot may be adjusted in any variation so the motion can be practiced for more than the fundamental perpendicular placement . in one aspect of the present invention , the plant foot can be placed adjacent the frame of the in one embodiment of the present invention the foot board has a foot pedal that has a shape conforming to the size or the shape of the user of the board . in a further embodiment the foot pedal is separate from the board and can easily be detached from and attached to the board . for instance the board has a cut - out of a specific shape wherein a foot pedal or a board containing the foot pedal fits snugly so that the foot pedal does not move relatively to the board . the board in a further embodiment is provided with fasteners such as rotatable clips that hold the foot pedal or a board containing the foot pedal tightly fixed to the board when put in place . such a replaceable foot pedal has several advantages . one can provide a foot pedal with the correct position with relation to the frame , thus providing the correct training position of the push -
