Using electronic muscle stimulators for body building provides nerve and flexor training for the muscles and seems to allow the muscle tissue to grow at a rate comparable to simple exercise. However, with the stimulators the body goes without the after-pain associated with strenuous weight training exercises. In this way the electronic muscle stimulators can help the body building enthusiast to better control the level of pain that is felt after a workout. Some people with problem areas such as sore shoulder muscles can use the stimulators to help alleviate the pain before the next session of exercising.

The same applies to anyone looking to lose weight with electronic muscle stimulator use. While the stimulator may help to alleviate the pain sometimes associated with weight loss exercising, the unit itself will most likely have very little to do with actual weight loss. However, by helping the person control any pain associated with the exercising, the stimulator may, in fact, help these people to exercise more. They will then have a better chance at losing more weight.

Electronic muscle stimulators have been thoroughly proven to help with physical therapy where nerve and muscle damage has occurred. Many therapists highly recommend the use of these units when their patients routinely complain of sore muscles during and after exercise workouts, or have some form of nerve damage that prevents them from getting the most out of life.

The effective use of these electronic muscle stimulators depends a lot on the type of patient and the nerve or muscle damage they may be suffering from. In general use, the stimulator units can be used easily by the patients themselves after only a few minutes of training. In this way, the patients control the amount of voltage used and the rhythm cycle that controls the rate of muscle contractions.
