starting positions
The wrestlers start the bout standing on opposite sides of the white circle; this circle is in the middle of the central wrestling area and is 3.2 ft in diameter.
standing position (Greco-Roman wrestling) 
In Greco-Roman wrestling, it is forbidden to seize the opponent below the hips and to use one’s legs for a hold or to defend oneself.
crouching position (freestyle wrestling) 
Freestyle wrestling allows the wrestler to use the entire body; this provides for a larger variety of holds than in Greco-Roman wrestling.
