CROSS-REFERENCE TO RELATED APPLICATIONS 
   This application claims the benefit of Application Ser. No. 60/809,192 filed May 30, 2006 for a Physical Training System. 

   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates generally to improvements in exercise equipment and more particularly, pertains to a new and improved physical training system uniquely adapted to the body of the exerciser. 
   2. Description of Related Art 
   In the field of fitness training for athletes such as boxers, it has been the practice to employ deadweight bags for training of the arms, and jump ropes, for example, for training of the legs. Such devices have been useful but are incapable of exercising a simultaneous combination of arm and leg muscles as needed in an actual bout. 
   SUMMARY OF THE INVENTION 
   The general purpose of this invention is to provide a physical training system for a boxer that not only trains the major arm and leg muscles as do the deadweight bag and jump rope, while at the same time providing training for the arm and leg muscles simultaneously in a more to simulate an actual bout. To do this, the present invention provides a left and right handle for grasping and a left and right foot fastener. A left elastic end is attached to the left handle and left foot fastener. A right elastic cord is attached to the right handle and right foot fastener. When the cords are being grasped by the handles as they extend from the foot fastener across the back and over the shoulders of the athlete, movement of the athlete&#39;s legs applies a resistance to the arms and movement of the athlete&#39;s arms applies a resistance to the legs.

     FIG. 5  shows the toe fastener  400  attached to the toe section  401  of a shoe  403  by the shoelaces  405 . 
   This invention provides a physical training device  200  that facilitates a workout where the aerobic efforts of the user&#39;s legs and feet simultaneously impacts the effort required by the arms.  FIG. 1  shows the physical training device  200  in operation. The physical training device  200  is particularly applicable to, but not limited to, training for boxing, tennis, baseball, basketball, football, and aerobic conditioning. 
   Cords  206 ,  207 ,  208 , and  209  which may be surgical rubber tubing may be made in small, medium, and large lengths. The thickness of the rubber for rubber cords  206 ,  207 ,  208 , and  209  can also be made in light, medium, and heavy thicknesses for different workout levels. The thickness of the rubber for rubber cords  206 ,  207 ,  208 , and  209  does not need to be the same for each. For example, a right handed person may want rubber cords  206  and  208  to be thicker than rubber cords  207  and  209 . A person may also want different thicknesses for rubber cords  206  and  208 . For example, a person may want  206  to be of medium thickness and  208  to be of heavy thickness for a workout level between medium and heavy. Webbing pieces  210 ,  211 ,  216 ,  222 ,  223 ,  228 ,  240 , and  241  can either be fixed in place or adjustable. 
   To use the physical training device, a user will first put on ankle fasteners  300  and  301  by placing the feet through the upper sections  302  and  303  and resting the heels against heel straps such as  306 . The user will then put on his shoes and interlace the toe fasteners  400  and  401  into the shoelaces of their shoes  403  at the toe  401 . The user then connects attachment hooks  202  and  203  to attachment rings  304  and  305 , and attachment hooks  204  and  205  to curved attachment loops  404  and  405 . The user will then grasp plastic handles  250  and  251  and manipulate the arms to position shoulder harness  234  in a comfortable location. 
   This physical training device  200  exercises several muscle groups at the same time. When the user makes a forward or lateral step with the right foot, web pieces  216  and  218  hold rubber cords  206  and  207  together, forcing them to expand, increasing the amount of resistance, and thus increasing the force required to make a step. This step will also force rubber cord  208  to expand and additionally increase the amount of resistance. In turn, the expansion of rubber cords  206  and  208  will increase the resistance to the user&#39;s attempts to fully extend the arm in a punching motion. 
   When a user extends the right arm forward in a punching motion, for example, rubber cords  206  and  208  will expand and increase the amount of resistance felt. This increased resistance will require the user to apply additional downward force in order to keep their foot planted. When the user throws a punch, they will likely be simultaneously extending their arm and leg, which will simultaneously increase the amount of force required to fully extend the arm and leg, due to the increased resistance provided by the expansion of rubber cords  206  and  208 . 
   There are a great number of exercises that can be done with physical training device  200 , beyond the motions described above. A user can perform any numbers of combination of arm and leg motions in conjunction with one another. The training device  200  is uniquely adaptable to the great variety of arm and leg movements possible in a number of sports. 
   Various modifications of the invention are contemplated by the inventor, and they obviously will be resorted to by those skilled in the art without departing from the spirit and scope of the invention as hereinafter defined by the appended claims.
