Take the ache out of running with the Double Glider added to your outdoor exercise area. With the growing awareness surrounding the damage that improper running can do to knees, more and more people are taking to the elliptical machine. The Double Glider is an outdoor version of the classic indoor machine. It is designed to handle, not only weather, but heavy usage over years. Simply put your feet in the foot holders and hold onto the hand grips to start your exercise session. It moves in a motion that is similar to walking and if sped up it can be very similar to running. The advantage is that it removes the classic grinding of the knee that happens during the “bounce” portion of a run step. The smoothness of the machine makes it an exceptional choice for areas that have a large elderly population as it is easy to use and takes some of the pain out of exercise.
