pendulum squat once known as 'swing squat'
Randy Coyle invented the first version of the SwingSquat back in 1979 (US Patent #5,626,548) and since revised the machine in 1997 with a new patent. Unfortunately, many of the larger equipment manufacturing companies infringed on Randy`s patent and started producing knockoff`s of Randy`s original design. Without the funds required to retain a copyright attorney, Randy had to sit back and watch his invention get copied and not get the recognition he justly deserved for his revolutionary leg machine. The other versions (Pendulum) aren’t a touch on the original and Randy, to this day, at 83 years old, still manufactures and produces Swingsquat leg machines.
