Selectorized machines or circuit machines were invented in the 1970's by the Nautilus Company. These are the fixed weight stack machines with the hole to insert the pin to easily select the weight amount that you want for your next exercise.

Eventually a series of 10 or 15 selectorized machines were placed in a line and called a circuit. This circuit was a complete body workout if you worked your way down from machine 1 to the end of the line.

The circuit training set up was the item that finally made the gym a place for people who wanted to get healthy, but were not body builders. Today the circuit machine is a staple in any fitness center and at UsedGymEquipment.com we sell the best at 70% to 50% of retail prices.
