This manual, which comprises both a theoretical and a practical section, addresses itself to all who are interested in the many and various uses of step apparatus during functional fitness and health training. The theoretical section gives an overview of aims, types of training and programme structure as well as methods of teaching and arranging. In the practical sections, basic steps, combinations of steps, arm movements and arm formations are described, as well as standard techniques, and set out in the usual terms. The section on technique is rounded off with a description of functional strengthening and mobility exercises with and at the step apparatus. The step aerobics programmes thus elaborated aim, on the one hand, at training general dynamic endurance and co-ordination; on the other hand, programmes are introduced, which also train strength and mobility. The programmes are designed so that they can be transferred straight into a practical teaching programme.
