After many years of research and development, Juliu Horvath began to make available to Gyrotonic Trainers the Pulley Tower Combination Unit, often called the Pulley Tower, and various versions have appeared over the last 20 years. These models may look slightly different, but the function is the same on all machines: the pulleys operate in the same way to produce constant and smooth resistance. The Handle Unit at the end of the bench has also remained the same over time, with small changes implemented that have made the brake and rotational mechanisms function more smoothly. The latest version is the Cobra Elite. Body Evolutions Studio is proud to be the largest studio in Manhattan, housing 12 of these units.
