Patent abstract
In an elliptical step exercise apparatus a dynamic link mechanism can be used to vary the stride length of the machine. A control system can also be used to vary stride length as a function of various exercise and operating parameters such as speed and direction as well as varying stride length as a part of a preprogrammed exercise routine such as a hill or interval training program. In addition the control system can use measurements of stride length to optimize operation of the apparatus.
