"Muscle stimulation"

Manufacturers of stim units claim their devices can help with everything muscle related. People endorse them. But before using these,make sure you understand how electric muscle stimulation(EMS)works. When attached to the skin,the EMS unit delivers a shock to the body's nerves that cause rapid muscle contractions. EMS works better towards recovery time(studies show being used on medical patients for muscle therapy). It is not a "short cut" or "quick fix" to top physical fitness.
