A swimming simulation system is provided, aspects of which include a dynamic bench, an arm cable pulley system coupled with hand grips, a foot cable pulley system coupled with a foot hold, and a resistance mechanism with attached gearing systems. All of the assemblies are operatively connected to a support frame. A user may lay face forward on the dynamic bench, or on their back on the dynamic bench, and pull the hand grips and/or foot holds to simulate swimming. The dynamic bench comprises a fixed center portion and independently rotatable sides that are interconnected at an interior edge to the fixed center portion and to biasing members at a point away from the interior edge. The side portions move independently of each other and provide a simulation of the yaw a swimmer experiences while swimming.
