The Func.Gym Pull involves the combination of muscles in the body needed to pull up itself to something or over something. The exercise can be performed with both hands or one hand at a time to create more of a climbing movement. The Func.Gym Pull comes with eight 5 kg Vulcano discs for a total weight of 40 kg. The unit features built in storage, so weights are conveniently kept on the machine and within easy reach at all times. Please note, if the machine is loaded with more weight than what it comes with, it must be equipped with floor mounts.
