I noticed that above 50 Hertz of ems rate, my skin is getting fried and the feeling of electricity rather than contraction takes over.
Is this normal ? I would really like to work at 100-150 hertz like it says on the articles but I just can’t… whats going on ? Why does it happen ?
I am not sure 50z is so good because the contraction is so deep and so intense that the muscle was extremely sore the following day…
