The Adjustable Dual Pulley is the ideal piece of strength buiding equiment as it is so compact that it requires only 20 square feet [approx] of floor space. It provides around 225 strength exercise options and is one of the most versatile strength training machines available. With two weight stacks, one for each handle, the unit has a more consistent feel than those that only use one weight stack. The low starting resistance and small resistance increments enable the user to increase the load gradually. The pulleys have vertical adjustment positions making it easy for users of all sizes to perform a wide variety of exercises.
