Best Muscle Stimulators For Recovery & Strength In 2022
Muscle stimulators have been around for some time though until recently they were mostly of interest to doctors and physical therapists. Today, however, they’re being put to use by a new generation of individuals intent on achieving a higher degree of physical fitness. Of course, they’re also often used in rehab and recovery. Muscle stimulators work to warm up muscles prior to working out, soothe achy and sore muscles in general, and can aid in recovery after a strenuous workout. EMS devices are regulated by the FDA so you can always be sure your device is safe and at least moderately effective if used as intended. Below are the best muscle stimulators on the market today.
I first found portable muscle stimulators after a back injury that I was struggling to get help with. A friend suggested it to me and let me try theirs out. I’ve now had my machine for several years and it still helps me manage my back pain to this day and helps me prepare my other muscles for big training days.

The Best Muscle Stimulator
The 7000 2nd Edition Digital TENS Unit is a full-service portable TENS kit whose main purpose is therapeutic. This TENS unit muscle stimulator can also be used to warm up cold, stiff muscles before a run or lifting session. This company has been building high-quality FDA-approved TENS units for more than a decade and all their experience is on display here. It’s super simple to switch between modes, customize the many presets, and the tough carrying case lets you bring it with you wherever you may roam.
I’ve been using this model for three years. The belt clip makes it easy to put the device in a pocket or on my pants so my hands are free. The modes are easy to change but you’ll want to look at the user guide for a better understanding of what each mode does. The intensity dials make changing things up mid-treatment easy but they have gotten slightly harder to turn over time. I’ve only replaced the battery and pads one time in three years of consistent use. If you suffer from back pain, be sure to check out our reviews of the best back braces and pick your favorite.

The Auvon muscle stimulator makes use of the TENS technology to effectively send pulsating electrical currents to the muscles and nerves of the body to help relieve muscle pain in a safe and natural way. What separates this product from others is its unique dual-channel mode of operation. Simply explained, this means that two separate recuperation procedures can be done at two different portions of the body, and at the same time. Alternatively, you can cover a larger area of the body like the back or quad with four electrode pads on the same program.
Additionally, with up to 20 pre-programmed modes, there are more options for nerve relaxation and deep pain elimination. The intuitive design of gel layers on the connector pads aids in releasing the electrodes from the skin after each treatment; this effective gel-stick design is also rated at 30 uses each, but according to the customer reviews, they’re known to last even longer. The lithium battery lasts up to 10 hours of use with just one charge. With a pouch provided and its lightweight design, carrying this stimulator is sure to be convenient.

The iReliev Combination Muscle Stimulator provides six preset EMS (electrical muscle stimulation) modes and seven preset TENS modes (including arthritis preset). Intensity can be set to any one of 25 levels while the timing on any mode can either be accepted as is or adjusted to suit your particular needs. Using electrical impulses, this unit provides muscle contraction and relaxation, helping not only relieve pain but also strengthen muscles.
The build quality is also first-rate. The fact that the different channels can be set independently is a big plus. And, at 80 mA, there’s more than sufficient power to tackle sore muscles or warm you up for the big game. Whether you suffer from back pain, Plantar fasciitis, or you struggle with muscle spasms, the iReliev is a great choice.

Why Trust Us
While I am not a medical professional, I am an avid user of a muscle stimulator for muscle recovery and chronic pain. I also consulted with my chiropractor who uses an EMS/TENS unit muscle stimulator in his professional practice.
Who This Is For
This guide is for the at-home user who is looking for a TENS muscle stimulator to add to their fitness routine, recovery routine, or for pain relief therapy. This guide is not intended as professional medical advice 0r for medical professionals.
How We Picked
To curate a collection of the TENS EMS units, I started with my own personal experience, and consulted our testing team and a medical professional. From there, we looked at the best sellers on Amazon and elsewhere to round out our guide.
How We Tested
Well, how else do you test these bad boys other than popping those pads on you and turning it on? I mostly use my EMS unit for pain relief therapy and on my back. It can be used on other muscle groups and to encourage muscle recovery though. I've been using my unit on my lower back for years, at least once a week.
Features To Look For In Muscle Stimulators
Battery life - The average life of a battery for an EMS device is around 10 hours. But be advised that the actual amount of time you get out of a charge will depend on the level of electrical stimulation, whether or not your device has an auto-shutoff feature, and, of course, the quality of the battery itself since not all muscle stimulators come with high-quality lithium-ion batteries. The first battery I used in my EMS machine lasted significantly longer than 10 hours; I didn't change it for nearly two years. That doesn't mean your battery will last as long though.
The number of electrodes supported - Most of the best muscle stimulators have 2-4 electrodes typically attached to the unit with 2 cords. Those units with four electrode pads usually have cords that split partway down which allows for two electrodes at the end of each. In rare cases, you’ll get eight electrodes, each with its own cord. Be aware that some physical therapists think having so many electrodes all firing at once is overkill. Although there are others who state with equal authority that even a large number of electrodes firing simultaneously won’t produce any negative results. Keep in mind your tens unit pads will become less sticky over time and will need to be replaced while the electrodes shouldn't need the same maintenance.
Programs and strength options - We love options. They’re what the 21st century is all about. You have more choices for more things than ever before and why shouldn’t that ethos extend to the muscle stimulator machine as well? The best muscle stimulators offer a range of performance options including various types of electronic “massage” and pulses intended to do everything from relaxing you after an intense workout to helping you recover after a traumatic injury. One thing this type of device won’t do is create muscle mass.
Muscle Stimulator FAQ
Q: What is EMS?
A: EMS stands for “electrical muscle stimulation”. EMS has received quite a bit of media attention in recent years for being an effective way to help people who have suffered from traumatic injuries regain use of their impaired limbs and as a way for athletes and others to warm up prior to working out. It has also found use as a way to help soothe sore aching muscles in the aftermath of a vigorous workout and as a general aid in training. While EMS may well help people warm up more effectively so they can optimize their workout efforts, EMS machines by themselves won’t create muscle growth but they can help "exercise" sleepy muscles. EMS machines are also often used in physical therapy and in Chiropractic practice to warm the muscles prior to adjustment. In the US, EMS machines are regulated by the FDA.
Q: Are muscle stimulators effective?
A: EMS is effective in helping people recover from injuries and surgery, warming-up prior to a workout, helping people relax, managing pain, and treating sore aching muscles in the aftermath of a strenuous workout. Many people also use the electrical muscle stimulation machine to help relieve pain and others as a way to help burn fat. Muscle stimulation can also help in the repair and recovery of joints that have been injured while playing sports. And EMS is being used to help those suffering from impaired movement (such as stroke victims) to prevent muscle atrophy and regain movement, if only on a limited scale.
Q: Do muscle stimulators help build muscle?
A: By themselves, muscle stimulation machines cannot encourage muscle growth. Why? Because muscle growth requires you to stress the muscle to the point that the muscle fibers actually tear. The body then moves in and replaces this torn muscle tissue with larger, stronger tissue. This tearing of the muscle is at least in part a result of working the muscle through the entire range of motion. Something an EMS machine simply can’t do. Electric muscle stimulation machines can, however, help you warm up more effectively and this, in theory, should enable you to get more from your workouts. Which of course means larger, stronger muscles.
Q: How long does TENS treatment last?
A: TENS is a kind of therapeutic treatment, rather than a way to enhance workouts (although there are those who have adapted it for that purpose). Therefore how long you experience benefits from a particular treatment will depend almost entirely on how aggressively you apply the TENS to the affected area and, of course, the nature of the affliction you are treating. That said, instances where TENS equipment actually resulted in damage from “overuse” are rare. So if you need to use the device several times a day there should be nothing stopping you from doing so.
Q: Who should not use a TENS unit?
A: As we mentioned, it’s unusual for TENS to result in actual physical damage, even when it is applied repeatedly over the course of the day and during any number of days in a row. However, there are some individuals who should not engage in this or any type of electrical stimulation without first consulting with their doctor, including:
People with a pacemaker - It is likely that any type of electric therapy device will present problems for people with pacemakers. While there are some pacemakers on the market today that are not affected by such devices, they are still relatively small in number. Therefore, you should never use this or any EMS device if you have a pacemaker unless specifically cleared to do so by your doctor.
Pregnant women - While the TENS device itself should present no threat whatsoever to the health of pregnant women, there have not been sufficient scientific studies conducted to be able to state with confidence that it poses no threat to the developing fetus. Therefore, the safe route is the right route and pregnant women should not use any type of EMS device.
Those with epilepsy - Epilepsy is a neurological condition related to the way electrical impulses are processed by the brain. Therefore, many doctors believe it is theoretically possible that engaging in electrical muscle stimulation could somehow initiate an epileptic seizure. It should be emphasized that there is at this time no conclusive evidence that this would occur. But neither is there conclusive evidence that it would not.
Lymphedema - Lymphedema is the result of a compromised lymphatic system and results in localized fluid retention in those affected. It’s thought that TENS treatment may aggravate lymphedema and perhaps result in ever greater amounts of fluid retention. Therefore those with lymphedema are advised to avoid electrical muscle stimulation machines.
