What is Electrical Muscle Stimulation ?

If you've ever visited physical therapy, you could have experienced EMS or "e-stim" to simply help loosen your tight muscles for them to recover. When used therapeutically, these units are created to stimulate nerves that produce muscles contract, ultimately relaxing and loosening any tight spots.

You can find actually plenty of these pain-alleviating devices available non-prescription and online (also called TENS — transcutaneous electrical nerve stimulation units), that may run you around $200. But, again, they're designed to focus on a particular area, not your system, and are typically used under professional supervision. Although these devices are often "safe and easy to use," using them throughout a workout is not advised and, if anything, should only be presented "for pain-relief effects following a workout," recommends Fulop.

Okay, just how is that different than an EMS workout?
Instead of emphasizing a specific body part as you'd do in physical therapy, during an EMS workout, electrical stimulation is normally brought to larger regions of the human body with a suit, vest, and/or shorts. As you exercise (which has already been engaging your muscles), the electrical impulses force muscle tissue to contract, that might bring about more muscle recruitment, says Dircksen.

It may sound simple enough, but it's no walk in the park. Since the pulse actually acts as resistance, the movements feel much harder and leave you fatigued much faster. Just as with other training, you could be sore: Overall, how sore you are after EMS training depends upon multiple factors, like the "intensity of the job, the weight used, the total amount of time, how much eccentric load was done, and if some of the movements were done in new ranges," says Dircksen.

So, does EMS workout training work?

When exercising normally, neurotransmitters in the mind tell parts of your muscles (and the fibers within them) to activate and engage to be able to perform each movement. With time, consequently of factors such as for example injury, overtraining, and poor recovery, muscular imbalances can occur and limit your muscle fibers' activation during moves when they need to normally be recruited. (See: Just how to Activate Underused Glutes aka Dead Butt Syndrome for a good example of how this can play out IRL.)

However, when pulseperformancestudio EMS is put into the equation, you're able to call upon more muscle fibers (including those that have remained dormant). To be safe — which means you don't overdo it and risk muscle, tendon, or ligament tears — choose "the minimal effective dose. Meaning, once you get a muscle contraction from the stim, that is enough," says Dircksen.

"By actively participating in a EMS workout class (rather than sitting and passively letting the e-stim activate your muscles), you're obtaining a good workout in, which is chock-full of health advantages," says Dircksen. Provided that you don't go overboard, this escalation in muscle engagement could end in strength gains. (

The Biggest Mental and Physical Benefits of Working Out
If you use e-stim in tandem with movement and weight, your muscles should get stronger than in the event that you did the moves alone, according for some research. In a 2016 study, those who did a six-week squat program with EMS had greater strength improvements compared to people who did not use EMS.

So yes, the idea of EMS workouts seems to produce sense, and, yes, some studies do support claims of boosted strength. However, research (of which there is very little) ranges in sample size, demographics, and findings. Case in point: A 2019 report on e-stim research actually found it had been impossible to make any conclusions on EMS training's effects.
