Bodybuilding is not a big sport here and there are no bodybuilding supplies or weights available anywhere so those devoted few gym rats need to be very resourceful. Here is an outdoor home gym I passed on today's ride. A bench press setup built of wood and the barbell is a thick stick with concrete molded to each end. Their dumbbell was two 3 pound coffee cans filled with cement with a big piece of rebar embedded as the handle.
Next time you find yourself grumbling about your gym, keep this gym in mind :)
