What Is An Ab Stimulator?

An ab stimulator is a belt that employs electrical muscle stimulation (EMS). The small electrodes attached to the belt pass an electrical current through the bare skin, causing the muscles in the abdominal region to contract. While EMS may sound similar to Transcutaneous Electrical Nerve Stimulation (TENS) devices, they have different uses.

TENS stimulates the nerves to provide therapy and pain relief, while EMS stimulates muscles to contract and is used for muscle retaining and to help prevent muscle atrophy in bedridden patients.

How Does An Ab Stimulator Work?

The principle behind the functioning of an ab stimulator is an electrical stimulation that causes the muscles to contract. This presumably helps in the strengthening and growth of muscles, acting as a substitute for your daily exercise.

The electrodes are attached to the bare skin and send electrical impulses through your skin. When the device is run at a low intensity, you may experience a tingling sensation, while when the intensity is increased, your muscles begin to contract.

Sellers’ descriptions for ab stimulators promise results after 6 to 8 weeks of continuous use for 10 to 30 minutes every day. Ab stimulators are regulated by the FDA. This means that the companies selling these devices should comply fully with all the FDA requirements. EMS devices are given clearance by the FDA for use in physical therapy and rehabilitation under medical supervision.

Very few ab stimulators are approved by the FDA. Since ab stimulators are EMS devices, an FDA clearance is a must. Here’s a list of brands that have got clearance from the FDA.

Let’s now understand more about EMS devices – what they are, how to use them, benefits, and caveats.

What Is An EMS Device?

Electronic muscle stimulators are devices that come under the Federal Food, Drug and Cosmetic Act. All the firms selling EMS devices should comply with the premarket regulatory requirements laid down by FDA before they can legally sell their stimulators.

Most of the EMS devices reviewed by the FDA are meant to be used for physical therapy and rehabilitation work that should take place under the supervision of medical professionals.

Electrical muscle stimulators are being advertised not only to tone, firm, and strengthen muscles but also to aid weight loss and girth reduction and for getting rock hard abs. But remember, no EMS devices have been cleared currently for weight loss, girth reduction, or for getting rock hard abs.

How To Use An Abs Stimulator

Here’s a list of steps that you need to follow while using an ab stimulator.

Step 1: Stretch the abs belt around your abdomen, ensuring that the large middle pad rests on your belly button. The smaller pads should lie on either side over the soft area of your abdominal muscles.

Step 2: Secure the ab stimulator belt. Ensure that the muscle stimulator pads lie snugly against your skin.

Step 3: Switch on the device by using the button located on the front panel of the device.

Step 4: Adjust the toning level so that you can feel your abs contract comfortably.

Step 5: Use the ab stimulator for the duration as recommended by the company.

Step 6: Once you are done, turn off the device, remove the belt and store it in a safe place until the next use.

Electric muscle stimulators are becoming quite popular products on the market. They claim to strengthen and tone your abdominal muscles. Listed below are the possible benefits of ab stimulators.

Benefits Of Ab Stimulators

  • Ab stimulators help to tone your muscles with minimal effort. The electric currents make your muscles contract. This helps you to stimulate your muscles while simply sitting at your work desk or watching television at home. The muscle contractions produce body heat that helps to speed up your metabolism.
  • Ab stimulators help in physical therapy. The FDA states that most of the EMS devices they review are intended for the purpose of physical therapy and rehabilitation environment and not for aiding in fat loss.


Devices that make health claims also carry a certain amount of risks for the users. The FDA has received reports of shocks, burns, skin irritation, bruising, and pain associated with the use of some of these devices (1).

You shouldn’t use an electrical muscle stimulator if you have:

  • Electrical implants like pacemakers and defibrillators
  • Undergone abdominal or other surgeries

Remember, all bodies are beautiful. The decision to look fit and healthy should be driven by health concerns and not to conform to some unrealistic societal beauty standards. The keys to a good and healthy body are a good diet and regular exercise. If you intend to buy an ab stimulator, we strongly recommend you speak to your healthcare professional before buying one.
