June 11, 2019

Are you trying to attain the perfect abs? Ab belts - also known as ab trainers or ab stimulators—have been used by many fitness enthusiasts for a long time they use electrical pulses to help sculpt your six-pack. Manufacturers of the muscle stimulators claim that they’ll strengthen your core muscles and firm up your body. They even go as far as promising you a full abdominal workout if you use these devices. But how do they work?

Ab Stimulators

Ab belts use electronic muscle stimulators (EMS) which are commonly used by physiotherapists in rehabilitation centers. These EMS devices act by sending electrical pulses to your muscles - via your nerves - which cause contractions.

Engaging in this process for as little as 20 minutes a day with an abdominal toning belt is enough to not only strengthen your core, but also improve your muscle tone.

What’s the best ab stimulator belt?

The Flex Belt is the best abs trainer on the market thanks to its Medical Grade Abdominal Toning technology and the fact that it works for males & females. You get a two-year warranty on the Flex Belt and it will work for anyone with a waist between 24 inches and 47 inches. Another reason this is the best ab stimulator is because of its FDA approval and the rechargeable battery that’s included with purchase.

Do Muscle Toning Belts Really Work?

So is getting abs that easy without breaking a sweat? Granted, the whole process seems too good to be true, which is why many people are sceptical and view them as a fitness scam. This is why we’re here to set the record straight.

Ab belts (ab stimulators) are effective at both strengthening and toning your abs but there’s a catch. For effective results, you can’t use muscle stimulators on their own. Rather, ab stimulator belts must be part of a holistic fitness routine which includes the following:

  • Eating the right food. In addition to using an ab stimulator you must follow a strict, healthy diet plan because let’s face it; the only way to show off your abs is if you have a low body fat percentage.
  • Along with healthy eating, you must also exercise regularly and focus on exercises that specifically target your abs and core
  • Regular cardio is also crucial to attain the perfect abs.

Ab Stimulators

FDA Approval

Safety is probably one of the first factors to consider before picking an ab stimulator. To allay your safety concerns, it’s advisable to opt for one that’s FDA cleared for its intended function. This means the product would have been tested and passed all quality & safety checks.

Examples of products that are FDA approved from our list include the Flex belt and Slendertone ab stimulators.

fda approved

Gel Pads

Make sure the ab stimulator you pick has gel pads. Gel pads are sticky devices found on your toning belt and are designed to ensure that you get the most out of your toning session. They work by evenly distributing muscle stimulating pulses for optimum comfort and toning.


When it comes to fitness products, you get what you pay for. It’s that simple. This is because the price of these belts usually reflect a number of factors including quality, performance and durability.

Usually, higher priced ab stimulators are designed to produce more electrical stimulation compared to their cheaper counterparts. As a result, you can expect quicker results because they’ll make your muscles work even harder.

Also, most higher priced muscle simulators are designed using high quality products and mechanisms so you can expect them to last long. We can’t promise the same durability with lower priced models.


Ab Stimulators vs Waist Trainers: Is There a Difference?

Many people refer to ab trainers as waist trainers, but are they the same? Unlike ab belts, waist trainers don’t use EMS technology. Rather they’re simply designed to contour your waist via pressure.

How Effective Are Ab Stimulators?

As mentioned earlier, muscle stimulators on their own won’t miraculously give you a six pack. You need to exercise regularly and eat clean for optimum & visible results.

How Often Must You Use Your Ab Belt?

Wondering how often you must use your ab belt? The duration and frequency will depend on the brand you pick because different brands have different instructions. But generally most manufacturers recommend that you use muscle stimulator belts between 10 minutes and an hour daily for optimum results. 

With some brands like the Flex belt waist trimmer, you can use them more than once a day.

How Soon Can You Expect Results From Ab Stimulators?

Results will depend on the brand you pick and how often you wear the ab belt. If you wear it frequently—and daily—then you’re likely to see results sooner. Generally, with most brands, you can expect results within 6 to 8 weeks. But as mentioned before, you need to use the belt to complement your fitness routine. This means also incorporating a healthy diet and cardio workouts.

It’s important to note that ab stimulators are only designed to strengthen your abdominal muscles but won’t reduce belly fat nor help with weight loss. The leaner you are when you start using your ab stimulator, the faster you’ll notice visible results.

Where Can You Use Your Ab Stimulator?

Many users appreciate the convenience these ab stimulators offer. Because most of them are compact and portable, you can carry—and use—the belts anywhere.

When Not to Use Ab Stimulators

Because of the electrical nature and mechanism of these belts, there are certain instances where you can’t use ab belts. Avoid using muscle stimulators if you suffer from any of the following medical conditions:

  • Heart problems
  • Diabetes
  • Cancer

In addition, ab stimulators must not be used by pregnant women because aside from potentially harming your baby, they’ll make you uncomfortable. And make sure that you wait at least eight weeks after giving birth before using these belts. Only then would your body have fully recovered from the pregnancy strain.

Final Thoughts

Ab stimulator belts have been around for decades. And if used properly and regularly you can also experience the benefits; from strengthening to firming your muscles. Depending on the brand you pick, you get to work your entire your body and not only your abdomen.

Always remember that ab belts won’t decrease body fat and will work best if you’re leaner. This is why it’s important to remove any unhealthy foods from your diet.

Also, forget the six pack if you only use them while watching TV! Get up, be active and get that body you’ve always wanted.
