This abdominal belt uses electrical muscle stimulation (EMS) to activate natural muscle movements using four electrodes and is battery-operated. The batteries last for six weeks, depending on the frequency of use. On average, a session lasts 22-31 minutes. This is a great offer for curious buyers. In addition, the display is easy to read in bright light and the menu was quite intuitive when we put it to the test. However, we found it slightly bulky under clothing, and the lack of backlighting makes it less comfortable at night.

There are different types of electrodes.
We carefully compared their ergonomics.
Support is a very important element.

The Slendertone Connect Abs can be connected via its app (Android or iOs).
Easy to install, this abdominal belt fits most waist sizes (from 70 to 140 cm) and provides good support thanks to its Velcro strap. When we tested it, we found it comfortable to wear. It is battery-operated and uses EMS technology with two electrodes that only need to be moistened with water and not gel, which ensures longer durability. However, it works the core muscles, but not the lateral abdominals. It has 5 programmes and 40 intensity levels. In addition, several functions make it safe and ergonomic. During our test, we found it easy to use thanks to its well-oriented LCD. However, we regret the lack of illumination for the display.
With its compact design and smart operation, this abdominal belt is very ergonomic. Easy to use and very useful for tracking your sessions, it allows users to reach their goals and get the most out of them. It is almost entirely managed via the app and the design is comfortable to wear. In use, however, we noticed the occasional synchronisation problem and bugs in the app that can sometimes hinder the smooth running of sessions.

How did we do the testing?
To begin with, we tested each belt in a variety of environments. We did both passive and active sessions, as sitting and standing can make a difference. This allowed us to evaluate the fit, support, volume and freedom of movement of each belt. As for the power supply, we tested their endurance and compared the autonomy of the models tested.
As for the durability of the electrodes or pads, we cannot say exactly how long they will last, but we were able to assess how much they wear out. We tested each programme and intensity to judge the ease of use and ergonomics of the screen (or application). Unfortunately, as far as actual effectiveness is concerned, we prefer not to draw any conclusions, as it depends on several factors (diet, intensity of sports practice, morphology, etc.).
How to choose your abdominal belt?
Even though the abdominal belt looks like a commercial tool, it can be used to support a person undergoing rehabilitation after surgery. However, it should be used with care to avoid negative impact on tendons and ligaments.
First, you should know that there are three types of models:
- The electrical stimulation belt: it works by sending electric pulses (not painful) through the abdominal muscles, resulting in muscle contraction. This system favours the firming of the muscles.
- The vibrating abdominal belt: it relies on its vibrations which cause muscular contractions and can thus stimulate targeted areas.
- The abdominal sweat belt: it stimulates sweating in the abdominal area.
In this comparison, we will focus on the first category, as it is undeniably the most effective and the one that best meets the expectations of the general public.
Here is a list of criteria to consider before buying an abdominal belt:
- Size: the first thing to check is that it suits your measurements. It is best to choose a model that can be adapted to your body shape, as you are likely to lose a few centimetres, and so you will have to adjust it afterwards.
- Comfort: for a beginner who has never used this type of device, the pulsations may seem violent at first. Thus, comfort should not only involve the absence of pain, but also the proper support of the electrodes placed on your body.
- How it works: depending on the technology, its electrodes and the parts of the body that can be worked on, the belt will be more or less versatile. Its session time will also be important so as not to trample on the time slot you have reserved for it. In the same way, if it works with batteries, it is necessary to ensure that they are resistant because, in the opposite case, it is better that it integrates a battery.
- Offered programmes: you should not only rely on the number of programmes recorded but also on the intensity levels which will allow you to personalise your sessions, according to your body’s needs. Some modes promote better recovery or are more health-oriented, while others are designed to firm up your figure or burn fat.
- Accessories: while most include an LCD screen with indications or can be adjusted with a remote control, others can be operated from an app that ensures reliable monitoring. The armband is used to work your arms, while a storage bag can be useful.
- Results: if users buy this type of device, it is to obtain quick results. However, note that there is no miracle and that it does not melt fat on its own. The use of the belt must therefore be accompanied by a healthy, balanced diet and regular physical activity. These daily gestures will help you to achieve your goals.
NB: remember that the use of a heart belt is not recommended for pregnant women, people suffering from epilepsy or cancer. Furthermore, to stimulate your muscle fibres in areas other than the abdomen, there is also the solution of electrical stimulators, which is much more reliable, according to the expert Karim Bennouri.
Other models we recommend
Beurer EM 35 (£50.64 upon publication): simple to use. Although it does not push performance to the max, we think this is one of the easiest abdominal belts to use, thanks to its clear interface and quick set-up. It has several electrodes to moisten, and up to five programmes and 40 intensity levels. Its price-quality ratio is very interesting, but during our test, we found that it lacks support, making it useless for very slim people.
Beurer EM 39 (£66.97 upon publication): for the abdominal and lumbar muscles. It stands out on the market thanks to its dual function, which acts not only on the abdomen, but also on the lumbar region. This prevents possible imbalances between the two muscle groups. The electrodes work independently and there is a safety stop. But apart from its independent mechanism, which is ergonomic, safe and durable, and its quick installation, we found during our test some defects in terms of support and it is cumbersome. In addition, it is energy consuming.
Other models put to the test
Slendertone Abs 5 (£76.83 upon publication): with its perfect fit and its great promise of mobility, it is, without a doubt, one of the best for sport. However, its recent price increase makes it less attractive in our opinion.
Slendertone Abs 8 (£129.67 upon publication): very discreet and ultra-comfortable, it is also one of the best for sports. It combines good power with clever ergonomics. However, its current price is a bit high.
Slendertone Abs 7 (£160.41 upon publication): after analysis, we relatively appreciated this belt which (apart from its somewhat disturbing installation and cable) impressed us with its comfort of use and its ergonomic and progressive mechanism. Like Abs 8, it combines active and passive programmes. It is compatible with several useful accessories, some of which are included. In addition, it contains 150 intensity levels for gradual progress, and the remote control is easy to read and use.
