Have a look at our reviews of Slendertone in order to get a comprehensive and quick guide in order to help you get the best abdominal muscle stimulator that will provide you with the most benefit, with an easy to use controller and a bunch of preprogrammed workouts in a single unit. 

Slenderton​e Ab Belt Key Features

The Slendertone Ab devices are made to be able to support the development of a strong abdomen area and they are designed to help to slim the stomach. It should be noted that they are not designed to be a weight loss device or even to help you to lose inches. They will not eliminate pockets of fat. What they will do is stimulate your abdominal muscles to help them to become more flexible, stronger and more defined after a while.

After you have used the device for around 6 to 8 weeks, you will likely see a visible change in the amount of definition you have in your abdominal pack, and you should also have a more flexible and stronger core that is better able to support your body throughout the day. The designers have made it in such a way that it can grow with the user, with a lot of the units coming along with 7 pre-programmed workouts and a controller that is able to raise or lower the intensity of the electrical impulses, having a range of 99 - 150 settings. 

The Food and Drug Administration has also deemed the units as being safe and effective, and a lot of independent studies have demonstrated users will receive definable benefits after they have used the unit for the entire 6 to 8 weeks.

They really are designed for a busy lifestyle, because it means that you don’t need to spend ages working on your abs. When you put it on and select a program, you can go on a walk, do some shopping or even get cosy on the couch.

Top 4 Best Slendertone Ab Belts


Slendertone Arms Muscle Trainer

You may be thinking it’s a little bit unfair that your abs are the only thing that can benefit from this miraculous technology - fear not, because the Slendertone Arms7 is here! This device has two units that are made to be able to fit your upper arms in order to support the development of your triceps and biceps. Similarly to the Abs belts, you can strap it on, choose the program and the intensity setting and then you can just allow the unit to be able to do what it does best for the 30 minutes following.

The device is designed to be a tool that supports better muscle growth, but it is not made to be a way to get rid of fat or as a tool for weight loss. If you did end up losing muscle as a result of an injury or a chronic condition though, the Arms7 will allow you to be able to rebuild and it’s also good for bodybuilders. It’s another great tool in your arsenal to allow you to retain your muscle when you aren’t in the gym. It has a similar remote control to the Abs7, so you will be able to adjust it in the middle of a workout without worrying about taking it off and then putting it back on.

Of course, this system isn’t actually modular, so you won’t be able to take the remote from the Abs and use it for the Arms7. Some smaller people have said that the arm units are a little too big to be able to fit nicely on their arms, but for those who work out a lot the fit is great. Some of the other users add the Arms 7 onto their leg workouts and they will attach the belts to their thighs and calves, which means it’s a lot more versatile.

If you want to be able to workout alongside an online community, then the Slendertone Connect may be a good choice for you. This device will provide you with the ability to connect it up with your Apple or Android operating system on your smartphone in order to act like a controller.

This device doesn’t come with a preprogrammed set of intensity levels, but instead is will give you total control over the whole duration of the workout, the level of intensity and then you will be able to show off your results on social media platforms that will give mutual support for others doing the same as you.

The belt is somewhat smaller than the Abs3 that we discussed earlier, because it only fits people that have a waist up to 42 inches. The belt is rechargeable which means that you could just put the belt on while you watch TV or when you’re working at your desk during the workday, giving you a workout while you get on with your day. It’s also possible to access personal coaches that will help you to be able to personalize your goals further and will let you share your achievements.

The programs that are on offer will focus on your abdomen and six pack, and this can help mothers on their post natal recovery. It will also help you with some easy toning when sit ups have not worked for you up until this point. Every Slendertone unit has been cleared as being safe and effective to use for the purpose intended by the FDA. This particular model does cost almost triple the amount of the Abs3, but you will also get the online community and the customizable programming.

The main benefit of the Connect is that it allows you to modify the intensity of the workout as you go, because your phone is already available to you and will show you all of the settings that are on the belt itself in both the Abs3 and Abs5 versions.  Unfortunately some users will report difficulty using the app on their Android phones. Because of this, you will need to ensure that your operating system can be used with the connect app.

  • Smart, Powerful Toning At-Home
  • The app-controlled ab belt that discreetly tones & firms your abs, anytime, anywhere
  • App-Controlled: control your belt from your mobile or tablet using the free Slender tone app


Slendertone Abs7 Abdominal Muscle Toner - Core Abs Workout Belt

This waist training will provide all of the flexibility on offer with the Connect version but it doesn’t have all of the functionality of a smartphone connection. The control panel onboard from the Abs3 and Abs5 is also replaced by a handheld remote that can be connected to the belt using a wire.

This will let you switch up the workout program when you’re in the middle of using the belt. This means that you can raise your game pretty much immediately, and you won’t have to wait for the next day when you begin your next session. This is also a significantly larger unit so it’s able to fit users that have a waist size of between 27 inches and 47 inches. This means a lot more people are able to take advantage of the key benefits of the waist trainer. 

It doesn’t have seven programs, it instead has ten already preloaded programs. The intensity controller also provides 150 settings in comparison to the 99 that can come with the Abs3 and the Abs5.

The waist trainer comes along with a two year limited warranty. This is a pretty reasonable warranty and a good expectation of the functional lifetime of the unit because the gel pads will wear out over time. The Abs7 is a middle ground between the Abs3 and the connect as far as price is concerned. It has a bigger size, a lot more programs and a handheld remote that means that it’s arguably one of the most versatile of the Slendertone models, and it provides great bang for your buck. 

There is one way to extend the general life span of the waist trainer, and that’s to use electrode gel. This will help you to be able to keep your gel pads soft and conductive, all while providing more of an electrical impulse to your muscles for some stronger, more effective contractions.

You can select the Abs3 programs using the onboard control panel. Of course, you are going to need to choose whatever program you plan to use before you strap it onto your belly.
