Electrical muscle stimulation works by sending an electrical current to the targeted muscle, forcing it to contract. EMS has received a large amount of attention in the last few years. Until recently EMS was primarily used with therapeutic purpose to help manage muscle and/or joint pain.

Recent studies have shown EMS being very effective when used for strength training. Athletes and actors use EMS during their exercise for greater muscle tension. As a result this helps stimulate working muscle resulting in greater growth. Several actors have used this technique to speed up their results when preparing for a certain movie roll. EMS can shorten the time a person needs to acquire muscle strength. Approximately 15 minute training session with EMS can have the same if not more impact then traditional one to two hour workout without stimulating the muscle using electricity.
