EMS Training Review | POPSUGAR Fitness

Must read


I’ve tried tons of different exercise styles, from yoga to HIIT to Pilates to rowing. But looking back, I can honestly say I’ve never been totally blown away by an experience. I’ve enjoyed plenty of workouts, of course, and I’ve had varying degrees of results depending on the style and the intensity, but they’ve all been relatively predictable and I’ve always been pretty sure of what the actual class was going to be like. Not so with EMS training.

EMS, or electrical muscle stimulation, is exactly what it sounds like: extra stimulation of your muscles to make your workouts more effective. The technology was originally used in physical therapy to help build back muscle strength after an injury or atrophy. Now, the EMS suits— literally a full-body suit full of electrodes that you wear while exercising — are being used to enhance workout.

The claim of EMS is pretty lofty, namely that a 20-minute workout is equivalent to two hours in the gym. “There is no other workout where you can focus on your arms, but simultaneously also have every other large muscle group working and completely activated,” says Anna Herrin, a model, trainer, and co-owner of The Studio EMS in Los Angeles. “EMS contracts up to 90 percent of muscle fibers and can help your body do up to 85 contractions per second.”

I decided to join the ranks of EMS-devotees Usain Bolt and Victoria Secret models Elsa Hosk and Alessandra Ambrosio and try the EMS workout for myself. Over the course of a month, I did eight 20-minute sessions (twice per week). Keep reading to learn about my EMS experience and my results.

What Is an EMS Workout?

EMS delivers electrical impulses to targeted muscle groups, stimulating the deep muscle fibers which are often hard to engage during regular exercise. According to Herrin, pairing these muscle contractions with movement makes for a very efficient workout, usually in just 20 minutes.

EMS is meant to target almost all of the major muscle groups in your body: inner thighs, hamstrings, abs, low back, mid-back, shoulders, chest, glutes, and arms. You can also turn off specific areas of the suit to just focus on the muscle groups you want to target. “With EMS, you’re working your whole body for the entirety of the 20-minute session,” says Herrin. Because the EMS suit is bypassing your brain and contracting your muscles for you, you have no other option but to keep your muscles fully engaged for the entire workout, she adds.

What Does the Research Say About EMS Workouts?

While most of the existing research behind EMS is generally positive, many of the studies were done on small groups — there isn’t much high-quality, large-scale research out there. Meaning, more evidence is needed before we can say for sure how effective it is or what the long-term risks are.

A 2016 study found that people who did a six-week squat program using EMS had greater strength improvements over those who didn’t use EMS; another study from 2021 showed that the set of women who did low-intensity resistance exercises three times a week for six weeks using the EMS suit had a significantly more improved body circumference and cardiovascular function than those who didn’t use EMS. Other recent studies have shown that EMS has positive effects on full-body toning, building bone density, reducing belly fat, and alleviating back pain.

Other studies, though, like this 2019 review of e-stim research, just say it has minimal effect. It’s interesting to note that most of the studies that show minimal effects were conducted on men, which may indicate that EMS is more effective for women. TBD.

My EMS Experience

Let me preface this by saying that I mostly do yoga, with the occasional barre or Pilates class thrown in. I don’t do a ton of cardio or weight lifting, and I had knee surgery in my 20s so I don’t do any HIIT training. I’m pretty fit, but not all that used to weight training — and EMS definitely humbled me.

With The Studio EMS, a trainer came to my house for each session. Most EMS trainers do in-home visits, but you may be able to find a gym that also offers the program. In order for the electrodes on the suit to activate, you have to wear activewear made from either cotton or tencel — other fabrics can disrupt the electronic stimulation. I got my shirt and capri set ($50) directly from The Studio EMS, but your trainer may also have a base layer that they prefer.

Before actually getting into the suit, it has to be pretty thoroughly drenched in water, which acts as a conductor from the electrodes to the muscles for a consistent electrical flow. So yes, you’re going to be wet during the workout, but it’s honestly not all that noticeable since you immediately begin sweating (or, at least I did).

Once your suit is wet, your trainer will strap you in. Be prepared for the suit to be tight — I’m talking corset-level tight. The tighter the better, actually, so that the electrodes don’t go sliding around and stay on top of their designated muscle groups. It does tend to loosen up during the workout, usually about halfway through, which Herrin says is because of a lymphatic flush due to increased blood flow.

Once I was strapped in my suit and on the mat, we always started with an easy squat warm-up while my trainer slowly started to crank up the electricity on each muscle group; the stimulation contracted the muscles for five seconds, then released for five seconds. The suits used by The Studio EMS are wirelessly hooked up to an iPad that the trainer uses to control the impulses on each area. I would tell them when it was starting to feel spicy and then we’d move on to the next muscle group, increasing the intensity on each specific muscle group throughout the workout.

The muscle contractions themselves aren’t painful, just kind of strange and tingly. It feels like you’re flexing your muscles as much as you can and holding them in that flex for five-second intervals. I’m one of those people who like to go as hard as possible while working out (without pain, of course) to get the best results possible, so I asked my trainer to keep punching up the intensity as much as I could tolerate throughout the 20 minutes.

As far as the actual workouts, they were mostly low-intensity Pilates-style exercises: a lot of lunges with leg holds and twists, dead bug and leg-lift ab exercises, and low-weight arm reps. On the face of it, they were pretty simple but the EMS suit made everything way more difficult. It felt like I was moving through molasses. Bicep curls with a three-pound weight suddenly felt like I was lifting a 20-pounder, and crunches — which I normally crush — left me totally winded. My trainer was very focused on linking breath with the movements and the stimulation intervals, as well as being really technical about my form.

Honestly, about 15 minutes in I was about ready to call it, which was wild for me since I’m used to doing 60 to 90 minute classes with ease. Twenty minutes truly is all you want to do with the EMS suit on, and I was drenched in sweat and tired AF after each session.

Two things to be aware of: One, you definitely have to get the hang of the feeling in your arms to make sure you’re not locking out your elbows. If I fully extended my elbows while the electricity was contracting my muscles, my arms would essentially get stuck in the outstretched position. Not the most comfortable! Once I got it in my head that I always needed to keep a slight bend in my elbows when extending, I was totally fine.

Second, if your suit isn’t tight enough and the electrodes move onto your skin away from muscle, it kind of zaps you. If that starts to happen, you just need to tell your trainer to readjust the suit. For example, some of the electrodes are over your pecs; these kept scooting down onto the top of my boobs and not over my chest muscles. Since pecs weren’t really an area I wanted to work out, we just decided to keep those electrodes inactive.

Overall, it’s a super challenging workout, but I felt really elated after each one. Herrin says this feeling is normal — and part of the reason why she loves the workout. “During your session, you will experience a whole new sense of mind to muscle connection,” she says.

As far as recovery went, the days after my first EMS session were the most intense. My hamstrings and inner thighs, which are always tight, were on fire and my arms felt like wet noodles. I took the two days after my EMS workout off just to stretch and go to a slow-flow hot yoga class, which helped loosen me up. “Since the suit is stimulating 90 percent of your muscle fibers, your body will be working overtime to repair the muscles throughout the next two days,” says Herrin.

Thankfully, I never had such a difficult recovery time after that first session — it kind of felt like my body was saying, “WTF did you just put me through?!” and then was more prepared each time. I typically did my workouts every three or so days, with mostly yoga on the days in between. Each session felt more and more natural, and I could feel myself getting stronger during each session.

Herrin recommends drinking a lot of water and taking it easy the following day by doing light cardio, gentle yoga, a brisk walk, sauna, or stretching. “You’ll be sore, so don’t push it!” she says. “We always tell people to feel it out after your first couple sessions. Some people feel the most sore they have ever been, and others get used to it more quickly. Herrin notes that, like most workouts, your diet and lifestyle play a big part in seeing results, so EMS workouts alone won’t transform your fitness level.

My EMS Results

After a month of training, what is most apparent is how strong I feel. I’m able to do things in my regular yoga classes that were once more of a challenge with ease. I feel this in my ability to do advanced arm balances in particular, which use arm, shoulder, and core strength. I also feel like my stamina has improved — I’m able to hold poses for longer, do higher-intensity classes, and go all out for longer before my muscles burn out.

In terms of how I look, my arms are definitely more defined and my stomach muscles feel as hard as a rock. I don’t believe I’ve lost any weight, however that wasn’t really my goal. I wanted to feel stronger, challenge myself, and build more lean muscle, all of which I feel like I accomplished.

What to Consider Before Trying an EMS Workout

If you’re pregnant, have a pacemaker or defibrillator, or have any metal in your body (talk to your doctor if you have a copper IUD), you shouldn’t do EMS. Otherwise, pretty much anyone can train using the suit. “Pretty much if you’re cleared to workout, you’re cleared for EMS,” says Herrin. “We have suits for every sized body.”

It’s important to know that some studies have linked EMS to an increased risk of rhabdomyolysis, which happens when muscle fiber contents are released into the blood, causing kidney failure. However, this is super rare and can be caused by any other intense strength training regimen or going too hard on your regular workout.

The FDA also warns about shocks, burns, and blisters with these devices. To make sure this doesn’t happen, make sure you’re going to a reputable trainer with an EMS certification, and steer clear of buying one of the suits to use on your own. The FDA has also only cleared certain suit manufacturers; you can always ask your trainer to show you the certification for the suit they use.

Is EMS Worth It?

EMS workouts are admittedly on the expensive side, mostly because the suits and tech itself is expensive. A single in-home session with The Studio EMS, for example, is $165. That being said, EMS should really be thought of as a complement to your normal workout; one to two-sessions per week is all you really need. If you’re OK with spending that much, I’d say EMS is absolutely worth it if you want to feel the strongest you’ve ever felt. I personally will be adding EMS sessions into my normal workout routine.
