I’ve tried a whole lot of unusual exercises within the title of science, however there was no expertise fairly like seeing myself in an EMS swimsuit for the primary time. It’s all black, with straps and buckles in every single place. An extended wire is about to attach me to a pc. I really feel like I’m suiting as much as function a spaceship or a large robotic. As a substitute, I’m about to do lunges and pushups whereas being informed that I’m getting a significantly better exercise than these suckers who simply go to a daily gymnasium.
To attempt it out for myself, I accepted a proposal of a free session at BODY20, a rising chain of EMS health studios. Its exercises are expensive, at $40 to $100 per session relying on the place the studio is situated and what sort of membership you join.
So, is an EMS exercise any higher than the common factor? In all probability not. (We’ll get into the main points in a minute.) However after seeing myself within the mirror, I sort of get the attraction.
What’s EMS?
Electrical muscle stimulation (EMS) exercises are having a second—not for the primary time, and doubtless not for the final—based mostly on their futuristic vibes and the health business’s fixed quest to promote you newer, cooler exercises than what everybody else is doing.
Electrical muscle stimulation is a household of strategies and applied sciences that set off your muscle tissues to contract by passing a light electrical present via your physique. It’s possible you’ll be conversant in among the different makes use of of passing electrical present via your physique for well being and health functions, so I will describe them for comparability.
For those who’ve used a TENS machine for ache aid, you realize one kind. You may put sticky electrodes in your pores and skin, and activate a handheld machine that is related to them by wires. TENS makes use of a light present that seems like tingling, nevertheless it doesn’t make your muscle tissues twitch or contract. The thought is that the tingling feeling interferes with ache indicators. TENS stands for transcutaneous electrical nerve stimulation, which means that {the electrical} present crosses the pores and skin and the feeling is picked up by your nerves, nevertheless it’s not designed to contract muscle tissues.
Alternatively, if you happen to’ve used e-stim at a bodily remedy appointment, that’s extra like what’s taking place in EMS exercises. After I was rehabbing after ACL surgical procedure on my knee, rebuilding my quad muscle was a excessive precedence. So I’d do leg presses and leg extensions, and on the finish of the session, the PT would sit me down in a chair and apply sticky electrodes to my thigh. He’d slowly flip a knob and my quad would begin contracting. Once we hit a degree that was mildly painful however tolerable, he’d depart the machine at that setting and we’d let the machine work my quad muscle for, as I recall, 10 minutes or so.
EMS exercises are nearer to the e-stim machine, however the expertise may be very totally different. Whenever you do an EMS exercise, you’re strapped right into a full-body swimsuit that applies present to a number of muscle teams without delay. The present isn’t as robust as in my PT periods, however you additionally received’t simply be sitting in a chair—you’ll be doing exercises whereas the electrodes make your muscle tissues contract more durable than they’d from the workout routines alone.
What occurs in an EMS exercise?
For my EMS exercise, I confirmed up at a boutique health studio in a suburban space, subsequent door to a veterinary clinic and within reach of a yoga studio. I needed to signal a waiver that included a disclaimer recommending I not take part if I had a pacemaker, metallic implants like plates or rods, or if I had epilepsy or most cancers, or was pregnant. There have been additionally gadgets on the checklist that referenced dehydration, historical past of rhabdo, “strenuous bodily train” within the final 72 hours, or one other EMS exercise within the earlier 5 days.
The studio supervisor ran me via this and defined that I’d solely be capable of do a reasonably brief exercise, with out weights, my first day. Over the course of a number of periods, persons are launched to longer and more durable exercises, though you’re by no means doing greater than 20 minutes in a session.
The realm behind the desk was separated into two predominant rooms. There was a small health studio with mirrors and black flooring, the place the exercises occur. Behind that was a room with an InBody scanner and a number of other locker-like cubbies, brightly lit, with an XBody swimsuit hanging in every.

(I performed alongside and received the InBody scan, although I do know it’s not very correct at figuring out physique composition. It gave me flattering numbers, so I can’t be too mad.)
I used to be given a set of garments to alter into, a black form-fitting shirt with three-quarter size sleeves and a equally cropped pair of pants.
I’d learn that some EMS studios advocate not sporting underwear; at this studio, it appears you’re meant to maintain yours on. Positive with me. I’ll simply be aware, for planning functions, that the garments you put on underneath the swimsuit will get moist. You would possibly need to deliver a change of dry lingerie for after.
Whereas I placed on the supplied exercise garments, a Body20 staffer sprayed down the within of the EMS swimsuit that I’d put on with water. As a substitute of sticking electrodes onto your physique, such as you would possibly with a TENS machine, these electrodes are constructed into the swimsuit. They every have an absorbent pad, and that is what she was wetting down. The water supplies a conductor between the electrode and your pores and skin. This implies you’ll find yourself with moist patches in your biceps, your stomach, your quads, your butt, and so forth.
There are not any electrodes in your calves or forearms, which didn’t shock me; they’re not excessive precedence muscle tissues for most individuals to coach. It did shock me that the deltoids (your most evident shoulder muscle tissues) aren’t lined by electrodes, both. This should be to permit for motion on the shoulder, nevertheless it appeared like an odd omission when these are an space that many individuals need to prepare, both for appears to be like or for useful causes.
The exercise itself was fairly primary, and brief. The swimsuit activates, and also you do a set of workout routines, like lunges or squats. Then it turns off and also you get a brief break—only a few seconds—earlier than you start once more.
Body20 gives energy and cardio courses. The energy courses are the primary occasion, it appears, and the principles prohibit you from doing them too typically. Cardio exercises are achieved with much less present going via the swimsuit, and also you’re shifting round from train to train, very like these body weight circuit coaching movies you could have achieved on YouTube. These exercises you are allowed to do extra typically.
The workers at Body20 stored referring to guidelines about frequency and depth as being set by “the FDA,” however once I requested about this in a follow-up e mail, I used to be informed that the principles really come from XBody, the swimsuit producer. The FDA does regulate EMS gadgets, and requires them to be cleared earlier than use. They are saying they’ve gotten stories of shocks, burns, and different points from gadgets which are illegally bought with out being cleared. Backside line, these guidelines from the producer sound cheap to me; I’d be cautious of shopping for any EMS gear if you happen to can’t confirm that it’s FDA-cleared.
What does an EMS exercise really feel like?

Very like my e-stim expertise at bodily remedy, the start of my Body20 session concerned the coach turning up the present and asking me to cease him when it felt robust however bearable. Too excessive, and it might really feel painful or crampy; too low, and also you won’t really feel something in any respect. (The e-stim at PT ended up being lots stronger than what we have been going for on this session.)
In the course of the workout routines, I might undoubtedly really feel the present making my muscle contractions stronger. A few times, doing a tricep motion, I felt my tricep form of lock up. It wasn’t painful, nevertheless it felt like my arm wished to remain straightened, virtually like a light cramp in my tricep.
There have been dumbbells within the room, however we didn’t use these for my introductory exercise. As a substitute, the coach had me maintain balls in my palms (like stress balls) and transfer them as if I have been curling a dumbbell or doing a tricep kickback. Due to the present, these did really feel like I used to be doing one thing.
That stated, it wasn’t a tough exercise. I stored listening to that I ought to anticipate to be sore afterward. As a substitute, I left the studio and headed straight to my weightlifting gymnasium for my standard Monday exercise (jerks, energy snatches, energy cleans, pendlay rows). I felt a bit extra fatigued than once I come to the exercise recent, nevertheless it was extra like “simply did a radical warmup” than “did an entire ’nother exercise first.” I used to be not sore the subsequent day.
For any person who doesn’t fling barbells round every day, it sounds cheap to anticipate some soreness. The lighter, shorter exercise for the primary session is sensible if you happen to don’t understand how your physique goes to react. However, based mostly on my expertise, it actually doesn’t really feel that totally different from a standard energy exercise. If something, it seems like much less of a muscular stimulus than a energy day on the gymnasium. You’re simply not doing that a lot.
Are EMS exercises efficient?
I’m a big-tent individual relating to train: if you happen to get pleasure from it, or if one thing about your chosen type of train will get you excited to do it and to maintain coming again, then I help you, whether or not that’s Pilates or powerlifting or something in between. I’m positive there are individuals who discover it enjoyable to do lunges in an EMS swimsuit, however who wouldn’t hassle doing lunges at residence at no cost. If an EMS studio membership is what will get you into the behavior (and you’ve got the money to burn), knock your self out.
However now we have to speak about one thing: the truth that each dang one in every of these studios makes a declare that EMS exercises are both higher than common exercises, or that they ship the identical ends in a fraction of the time. For instance, Bodystreet says you “solely want to coach 20 minutes per week.” Tummo says “One 20 minute session is the same as 3-4 days within the gymnasium.” We202 says {that a} 20-minute class “equals 3 hours of conventional coaching.” Fitopia claims that its 20-minute exercises “are equal to 90 minutes of standard exercises.” Body20, the place I went, isn’t any exception: it say its courses allow you to “obtain ends in simply 20 minutes that might require hours in a conventional gymnasium.”
So, in fact, I requested about it. The PR one that had launched me to Body20 despatched a listing of research, and pointed particularly to this 2016 examine that in contrast complete physique EMS to excessive depth resistance train. It concluded that EMS exercises “may be thought-about as a time-efficient however [pricey alternative] to [high intensity]-resistance train for individuals aiming on the enchancment of basic energy and physique composition.”
I dug in, desperate to crunch the numbers. As promised, the examine included an EMS exercise much like those provided by Body20 and different studios. And it did discover that each the EMS and non-EMS teams had comparable will increase in muscle mass and energy.
However the declare that you simply want hours within the gymnasium to equal one EMS exercise? That was not backed up in any respect by this examine. The non-EMS exercises have been half-hour lengthy. (Or, to be extra particular, 30.3 minutes plus or minus 2.3 minutes.) Even when the remainder of the examine’s outcomes are fully true and reliable and apply to you personally, you’re solely saving ten minutes per exercise, not hours.
And I do have my doubts in regards to the applicability of the examine, even except for the time concern. The examine was achieved on 48 wholesome males between the ages of 30 and 50, and all have been “untrained,” so the outcomes should be taken with a grain of salt. Virtually something works on individuals with no train background. For those who already go to some sort of gymnasium or health studio, and are pondering of switching to EMS exercises, I wouldn’t anticipate a lot from EMS, to be trustworthy. It could be simply pretty much as good. It could be worse. We don’t have proof that it might be higher.
Taken collectively, I feel the solely motive to do EMS exercises could be if you happen to suppose it’s a enjoyable solution to spend your cash. (All of us have our indulgences and our foolish hobbies; possibly that is yours.) It’s not a better or higher solution to work out than going to a gymnasium, or taking over some sporty interest like working or mountaineering.
