Retro vintage fitness machines

When I go to the sports club, I have various kinds of fitness machines, but it seems that I used to keep my body using fitness machine from long ago. At that time, the fitness machine has a retro feel and has a taste.

Image is from below. Machine to train abs. It differs considerably from what is now.
