Push it to the limit with the Imperial Double Leg Press. This structure can be placed on playgrounds or in exercise parks to help those who wish to work out their lower leg areas such as the quadriceps, hamstrings, hip abductors and gluteus-maximus. To use this machine simply sit upright in one of the two seats, place feet on the footpad with knees bent, then extend the legs until they are straight. This is a simple exercise that can help stretch and warm up the legs before strenuous workout or cardio such as swimming or running. The Imperial Double Leg Press is powder-coated in gray and green colors that will withstand rusting or cracking. It will also last against constant weather use. This structure is designed for kids 13 and up and kids under that age should be supervised.
