Buying guide for best ab stimulator

Living a healthy lifestyle can be challenging, but there are ways to get started on your fitness goals without overexerting yourself. We don’t want to mislead anyone since the only way to be fit, burn fat and lose weight is to exercise and eat healthy, but it doesn’t hurt to have some help along the way on your mission to increase muscle strength and build rock-hard abs. 

That’s where an ab stimulator can be a helpful tool. An ab stimulator isn’t a magic pill by any means, but it contracts and stimulates muscles in a way that helps strengthen them when combined with regular exercise and a healthy diet — without the need for girth reduction or a major surgery.

An ab stimulator provides electrical muscle stimulation and is excellent for strengthening your core, alleviating sore muscles after a workout and managing chronic body pain. The best ab stimulators have multiple modes and settings for customized treatment, and if used regularly, they can help you slim down, burn belly fat and tone muscles in two to three months.

Things to consider when choosing the best ab stimulator belt

Understanding your fitness goals

An ab stimulator alone won’t magically transform your current body or get you the lifestyle you want, but when combined with physical activity and good nutrition, it can help you achieve your fitness goals and possibly even help you get rock-hard abs. If you want a lean body, a strong core and toned abs, an ab stimulator works great, as it contracts those muscles and improves blood flow. It’s also excellent for physical rehabilitation, helping to alleviate sore muscles, manage chronic pain and improve range of motion. Plus, you can treat muscle spasms and use it effectively for neuromuscular electrical stimulation training.

Aligning intensity and built-in programs with your goals

Most electrical muscle stimulators feature several preset modes and intensity levels. Preset modes are great since you don’t need to tweak settings yourself and can just sit back and see which one feels best. It’s also a good idea to consistently work in different modes. That way, your abdominal muscles are stimulated by different pulses in different ways, which can be beneficial for core strengthening.

The intensity increases the electrical pulses and the duration of each pulse, meaning the higher the intensity, the harder your muscles work. You can start at the lowest intensity and gradually build your strength up to the highest intensity.

Picking the correct belt size and pads

An ab stimulator belt should be long enough to fit comfortably around your waist. Most ab stimulators are one-size-fits-all and fit waists of 40 inches or less. However, some ab stimulators have adjustable belts that can accommodate larger waistlines. A wider belt can target a larger portion of your abdomen, which is desirable for most people, as the larger surface area provides greater toning and covers more of your body for improved electrical muscle stimulation

Selecting the controls and battery type that fit your lifestyle

Ab stimulators require batteries. Some take AA or AAA batteries, which are easy to find when you need replacements. However, the cost of replacement batteries can add up over time, so consider investing in one with lithium batteries that can be recharged via a USB cable, such as the MarCoolTrip MZ ABS Stimulator. 

Selecting the ab belt that fits your budget

Ab stimulators vary in price based on the number of intensity levels and built-in programs offered. You could pay as little as $25 or as much as $300 for one.

If you’re a beginner and want something inexpensive, be prepared to pay $25 to $50 for an ab stimulator that has 15 to 20 intensity levels and three to four built-in programs. For an affordable ab stimulator, the Belifu Dual Channel TENS EMS is a superb option.

For greater customization, consider a mid-range option in the $50-to-$100 zone. Mid-range ab stimulators usually offer up to 50 intensity levels and five to six built-in programs. A person who has been using an entry-level ab stimulator and wants to upgrade could do well with one of these. A great option in this price category is the MarCoolTrip MZ ABS Stimulator.

The most expensive ab stimulators, in the $100-to-$300 range, offer up to 150 different intensity levels, which is why they often provide the most obvious results. They usually have six or more built-in programs and are ideal for individuals who are committed to a comprehensive diet and ab-sculpting exercise program. The Flextone Abs Stimulator Muscle Toner is an excellent choice.

Tips for using an ab stimulator

  • Consult your doctor before using an ab stimulator. The electrical stimulation may not be suitable if you have certain medical conditions, such as diabetes or epilepsy.
  • For maximum effectiveness, the gel electrode pads must be placed on bare skin. Ensure your skin is clean and dry before applying the pads.
  • Be sure to center the gel pad directly over your navel when you put an ab stimulator around your waist. 
  • Until you know how you’ll react, it’s best to sit down during your sessions. It’s not uncommon to feel dizzy or lightheaded when using an ab stimulator. 
  • If you’re new to electrical stimulation units, begin at a low intensity. You don’t want to overtax your ab muscles.
  • Turn the ab stimulator off before readjusting the placement of the gel pads.
  • Best results typically come from using an ab stimulator five to six times weekly. Don’t forget to give your muscles time to rest periodically, and don't expect your muscle size to increase overnight.


Q. Does it hurt to use an ab belt?

A. No, but you’ll likely experience a tingling sensation when you first start using electrical stimulation on your body. It’s also normal to feel your muscles tighten or contract as the electric impulses target them.

Q. Can I use an ab stimulator to tone my stomach after I’ve had a baby? 

A. Electronic muscle stimulators can help you tighten and tone your stomach postpartum if you feel your body has undergone significant muscle atrophy, but you should only use it when it’s safe to do so. If you gave birth vaginally, wait at least six weeks after the baby is born before using electrical stimulation. If you had a cesarean section, wait at least three months. In both cases, you should consult your doctor first to ensure they’re onboard with your plan.

Q. Can you overuse an ab stimulator?

A. Yes, you can. You should always follow the intensity guidelines and recommended usage times to prevent injuries. When you overuse electronic muscle stimulators or use too high of an intensity, you can cause muscle damage or destroy muscle cells. Needless to say, you’ll also be very stiff and in pain the next day. 

Q. How long does it take to see results?

A. Achieving fitness or rapid weight loss doesn't have a quick solution, and it takes time for any exercise to yield results. This also applies to abdominal stimulation; based on various studies, participants typically began noticing measurable results and increased abdominal strength after four to six weeks.

Q. Do ab stimulators work?

A. There are studies indicating that ab stimulators do indeed work. In the Effects of Neuromuscular Electrical Stimulation Training on Abdominal Strength study published by the Journal of Sports Science and Medicine, researchers found that when using only an ab stimulator, participants had a 58% increase in abdominal strength, had a 100% increase in abdominal endurance, and waist circumference decreased by 1.3 inches. Participants in the study felt that midsections were more toned and firmed, and just over half felt that their posture had improved as a result of the stimulation. 

A JOSPT study found that it can be an effective physical therapy tool as well as, concluding that combined use of electrical stimulation and volitional exercise was the most effective mode for isometric strength gain of the abdominal musculature. That makes them suitable for neuromuscular electrical stimulation training and physical therapy.

Q. Are ab stimulators safe?

A. As with all medical devices, there is an inherent risk in using them. For the most part, it comes down to how the device is operated and whether the user follows the recommended guidelines. When used correctly, ab stimulators are safe.

In a separate study published by the NIH, researchers conducted a similar test to determine if the health claims about ab stimulators were true. Not only did the study’s participants report a decrease in waist circumference, but the study notes, “EMS offers an effective and safe treatment” and “without side effects.”

The federal Food and Drug Administration has also cleared several ab stimulators for prescription use in treating medical conditions, while one over-the-counter EMS has been cleared for personal use. 

However, the FDA warns it has “received reports of shocks, burns, bruising, skin irritation and pain associated with using some of these devices.” In most cases, this stems from the cables and wires malfunctioning or interfering with pacemakers and defibrillators.

A note on the effectiveness of ab stimulators

Although there are studies suggesting that ab stimulators are effective, the best way to stay fit and maintain a healthy lifestyle is to have a balanced diet and exercise regularly, with the primary goals being lowering body fat percentage and increasing muscle health. It’s widely acknowledged that physical activity and proper nutrition yield many health benefits, from burning more calories and losing weight to achieving a slimmer waist size and building muscles. 

According to an NIH study, “There is incontrovertible evidence that regular physical activity contributes to the primary and secondary prevention of several chronic diseases and is associated with a reduced risk of premature death.” Electrical devices are great when used in tandem with abdominal exercises.
