The biggest problem beginning wrestlers have is chaining techniques together. They expect that they will always score the take down with the first attempt. If they fail, then just abandon all hope.
Wrestling is like life – you have to keep pushing forward regardless of the obstacles present. In this case, learning how to “reshoot” will give you a second, third, or fourth chance at securing the take down.
If you have ever done “duck walks,” then you already have the footwork done. This is just a simple drill to learn how to reshoot into all sorts of shots, whether it is a double leg, head inside single leg, or high crotch.
