Select options Back Electrode 99,90 € – 109,90 € incl. 19% tax The SPEEDtrainer electrode system consists of a total of six pairs of electrodes, which are attached to the actual muscles by means of velcro bands. As the appropriate size for every area of the body can be individually selected, the electrodes can be positioned with optimal pressure strength. Thanks to the patented electrode technology, a large-scale and even muscle contraction is reached. Even muscles that are located far away from the electrodes can therefore be reached, which results in a pleasant and intense training feel and outstanding training effect. The arm electrodes are placed in the middle of the upper arm and transfer the pulses to the arms. The electrodes are connected to the distributor of the SPEEDtrainer with the electrode cables. The electrodes are equipped with a coloured 6.3mm jack plug, of which the colour corresponds to the colour of the respective socket in the distributor. At the other end, there are two threaded inserts connecting it to the ports of the electrodes. One set of cables consists of six cables with different lengths which are each individually colour-coded.
