A multi resistance ratio exercise apparatus may provide at least one arm assembly which includes multiple flexible connector ends exiting which can be pressed or pulled to perform user defined functional and strength training exercises. The method can comprise a combination of electrolysis and ion exchange followed by melting to produce cobalt of a desired purity. The protective film is provided on a side surface of the base so as to be integrated with the base. The method identifies positional relationships between successive primitive graphic elements in the drawing order. In the direction of the magnetic field applied by the vertical bias layer, the free layer is made greater in length than the fixed layer and the free layer is disposed in proximity to the vertical bias layer with the distance between the fixed layer and the vertical bias layer remaining unchanged. The application also relates to a method of making surface-treated inkjet media, including providing a base stock including cellulose paper and applying a surface treatment composition to the base stock.
