Flex Belt Review (New 2020) – An Easy Way to Get the Abs of Your Dreams?


Flex Belt 

Many people around the globe are placing more and more emphasis on attaining a healthy and fit body. This can be achieved by working out at the gym, taking part in a physical activity, or simply following a clean and healthy diet plan. For most dieters, exercises are just like therapy, where one’s body and mind are both worked on.

Over time, individual goals start to fluctuate but the goal that almost every person has is to achieve a toned and ripped stomach. However, since our bodies store lots of fat around our belly and waistline, results can be difficult.

Today we will be looking at a highly popular product that claims to create amazing ab muscles without the need for any exercise, and that product is called Flex Belt.

What is Flex Belt?

The Flex Belt is an FDA-approved garment that is specifically made to tone, strengthen and firm one’s abdominal muscles. Instead of spending your valuable time in the gym sweating and performing hundreds of crunches, you could simply put on the Flex Belt and let it do all the work for you. Mainly, this belt is said to use a special EMS technology that targets the ab muscles over and over, performing the workout on its own. Even though this product might seem a bit intimidating, users are said to feel no pain at all during the process. The belt itself has a lightweight design, making it very portable and easy to use.

How Does Flex Belt Work?

As mentioned above, the Flex Belt works with EMS technology, or electrical muscle stimulation (1) (2).
This type of technology was used for years, mainly by physicians, physiotherapist, and chiropractors. Athletes and physical therapists have also used EMS in their training, rehabilitation, muscle toning, and recovery. During electrical muscle stimulation, low-level electrical currents are used to target the muscles, causing them to automatically contract. Instead of stimulating the muscle tissue with brain signals, EMS products stimulate the abdominal region using nerve impulses (3).

The EMS circular technology should contract the abs 360° up to ten times per second. And using the Flex Belt for only 30 minutes every other day for 4-8 weeks should supposedly create lasting results.

In addition to exercising, the Flex Belt also stimulates circulation in the treated area. The increased blood flow tones the skin and clears subcutaneous debris. By improving the condition and performance of the body, Flex Belt helps users feel relaxed, refreshed, and revitalized (4).

The Science Behind Flex Belt

The manufacturers of Flex Belt mainly rely on a 2008 6-week clinical study conducted by Dr. John P. Porcari, a professor in Exercise and Sports Science at the University of Wisconsin- La Crosse (5).

The results of this study concluded that all participants who underwent the EMS treatment experienced a more toned and firmer abdominal look than before, and the majority even reported an increased muscle firmness in that area. Further testing, used isokinetic dynamometry and an ACSM sit-up regimen that showed a significant improvement in abdominal strength and endurance.

So looking at these results, we can say that Flex Belt has a solid scientific foundation. However, these are the results of only one study, not to mention that diet and overall physical capability were not considered.

Flex Belt Results

The results you receive from the Flex Belt will depend.

In order for us to explain this further, it is essential to mention that all EMS devices must be registered with the FDA in order to be sold in the United States. So, while it’s definitely a positive thing that Flex Belt is FDA approved, it doesn’t mean anything significant. Or simply put, the company is just complying with the law.

Now, according to the FDA, EMS electrical stimulation may tone, firm, and strengthen abdominal muscles, but is not cleared to “provide weight loss, girth reduction, and rock hard abs.” On the other hand, EMS devices like the Flex Belt can potentially provide a variety of benefits, including “muscle re-reduction, relaxation of muscle spasm, increased range of motion, prevention of muscle atrophy,” and much more.

So what can you really expect?

The 8-week study that did conclude amazing results and the FDA seal of approval means you really can expect miracle results from the Flex Belt. Sure, this product can help you to slightly tone and strengthen your ab muscles, but again, you should not expect the “extraordinary” results shown in most Flex Belt commercials. Diet is another factor that plays a huge role in the Flex Belt results since proper dieting and a caloric deficit lower body fat which is key to visible abs. With a crappy diet plan, you really shouldn’t expect any major changes to your physique.

How to Use the Flex Belt?

The Flex Belt is very user-friendly and only takes three easy steps to set up. These include:

  • Charging the controller unit
  • Connecting the controller unit to the Flex Belt
  • Attaching the gel pads to the Flex Belt

It’s a very straightforward process that you will learn after the first session. The Flex Belt itself has only three main buttons along with two sets of up and down arrows that are used for intensity. All you have to do is to put on the Flex Belt and hit the power button, after that, you will choose the intensity you would like the Flex Belt to work on and you’re done. The Flex Belt also comes with a fairly big display that provides some simple information, like the timer, keylock function, and more.

Flex Belt Side Effects

Since we already mentioned that Flex Belt is FDA approved, this garment can’t really be that harmful. Overall, Flex Belt has gotten mostly positive customer experiences, but still, there have been some reported issues regarding the Flex Belt battery that has to be recharged after each use. Because of its frequent use, the Flex Belt battery can, but mostly won’t produce mild electroshock that could be painful. Some users also reported mild skin irritations and a warm and tingling sensation throughout their midsection.

Flex Belt Pricing

The Flex Belt can be purchased online through Amazon, eBay, Walmart, or through the official Flex Belt website.

Each package contains three gel pads, a rechargeable power unit, a belt extension, and an instruction manual. As far as pricing goes, it all depends on the quantity you decide to buy.

In the end, the only real way to effectively reach your weight loss and fitness goals is to eat healthily and exercise regularly. There’s simply no way around it.

Sure, Flex Belt might help you get strong and toned abdominal muscles, but this product can still not burn off the fat from your stomach and waistline. In other words, if you really want to achieve the rock hard ab look there is no way around hard work.

Instead of spending hundreds of dollars on a belt, we would recommend speaking to a personal trainer about the effective methods for achieving a firmer and slimmer belly. Combine those methods with a healthy diet and supplementation, and your desired results can be achieved.
