The Shock Series brings Bolt's commitment to forging champions into the commercial gym market. The first thing you’ll notice about the Shock Series machines is the sleek, modern design. The weight stack is housed in a trapezoidal case made of laser-etched steel and polycarbonate glass to give the platform a distinct outline that is especially striking when placed in a line with other Shock Series machines.
