Yes, Flex Belt works as advertised. In a six-week clinical study, more than 95% of participants said that their abs felt more toned after using the belt. Another 92.3% of users stated that the firmness of their abdominal muscles increased significantly.

A separate 8-week clinical research showed that the average participant received up to 49% increase in abdominal strength and 72% increase in abdominal endurance. The findings of a study published in the Journal of Sports Science and Medicine in 2005 show that the belt works when used 20 to 40 minutes per session. Dr. John P. Porcari, Ph.D., Professor, University of Wisconsin–La Crosse, conducted the study.

It may also catch your attention to know that the FDA approves the use of Flex Belt. Besides, the belt has attracted rave reviews some dating as back as 2014. Most users appear to rate it positively. Some of the reviews appear on the device’s official website.

This is important for a first-time user. It allows you to get a feel of what to expect with the belt. Of course, the high ratings mean that a large percentage of previous users benefited from using Flex Belt. However, to get the desired results, you must use the belt on a regular basis.

How Does The Flex Belt Work?

The Flex Belt works by toning your abdominal muscles. Once you strap it around your stomach, it will stimulate the nerves. It will also contract and relax adjacent muscles.  The belt’s official website says that this action results in a pleasant, pulsing sensation. You may increase or reduce the intensity from 1 to 150.

Flex Belt also uses gel pads to tone your abs. These are medical-grade devices that attach to your skin. They work by transmitting electric impulses to your abs. Again, Flex Belt’s website says that the pads last about 30 sessions. As stated, you will have to replace them after this.

While Flex Belt will give you results, it is important that you eat healthy meals. You may also want to work out at the gym once in a while. That way, you will get lasting results. The belt works well for both men and women at any fitness level with no side effects.

Note – the instruction guide states that you should consult your physician before using the belt if you have had a spine injury, have some serious back pain, are diabetic or have recently undergone a surgical procedure. You should not use Flex Belt on children or as part of your joint/muscle rehabilitation program.

  • Start by charging the controller unit
  • Connect the controller to the belt
  • Attach the gel pads to the belt

The Flex Belt features three buttons for operation. There are also two sets of up/down buttons to control the intensity and the on/off button. And because the buttons have clear labeling, there is no chance of getting confused.

The LCD is large and easy to read. It allows you to track the results at any given time. If you’re a first time user, these tips will come in handy;

  • Make use of the auto shut off time – it will help save battery power.
  • You may want to switch off the sound if you’re in a quiet room such an office. However, this is a personal preference.
  • The keylock function is helpful. It ensures that you don’t accidentally tamper with the intensity controls or any other button while wearing the belt.
  • The pouch on the Flex Belt helps keep the controller safe when you’re standing up
