Electronic muscle stimulation is most beneficial for people who have limited mobility. However, it is very useful for people who do not exercise regularly or want to tone specific muscles. For example, it can be helpful for toning tummy muscles after giving birth or for specific muscle sets that require "extra" attention. Don't let someone convince you that it will help you lose weight. It will not. However, when used regularly, the toned muscles will give the body a tighter smoother appearance. You will not lose weight, but you will lose inches.
