for the exerciser to go through all the modules is previously established such interval may depend on the time taken at each module for example if the exerciser spends equal periods of 5 minutes and 15 seconds at each module the total duration of the cycle will be 42 minutes in turn the period spent at the module may be divided into n phases for example there may exist n 7 phases of 45 seconds each whereof six are change and exercise ce phases designated as ce 1 ce 2 ce 3 ce 4 ce 5 and ce 6 preceded by a phase ri of recovery and instruction this latter phase has three main purposes enabling the exerciser to enter the circuit providing a time for recovery and or instruction on the exercise cycles of the new module such instruction being based on the display of the exercises to be performed on the video terminal of the module enabling the exerciser to leave the circuit whereupon the information is sent to a central control means of the system providing an interval for change from one position to another within the module monitoring the maximum exercising time within the position feeding back the exercise movie captured by the video camera in the last position where such movie may be stored in the memory of the central control means for later use or may be played back by the video terminal of the module a u201c movie u201d or u201c film u201d is to be understood as constituting a sequence of images captured during a given period of time as occurs in a tv clip for example in fig1 a there is shown an embodiment of the invention in which the structured space comprises eight.
