Waist trimmers are also known as waist belts and are worn around the waist. The belt holds the waist in, providing an illusion that the mid-section is smaller than it actually appears to be.
The waist trimmer has been used at times as a belt that supports the back of those who may need a little extra support when working out or walking.
Wrapping a waist trimmer around your waist will make you sweat more than usual during an aerobic routine. The perspiration allows you to lose weight during your workout. Simply run, jump or perform step aerobics or weight lifting activities and you will notice a difference. After you take off the waist trimmer, there will be a lot of sweat in the stomach area and maybe throughout your entire body.
Some people purchase the dual set, which comes with one waist trimmer for working out and another for going under your clothes. By wrapping it around your waist under your clothes, it covers up the flaws of a bigger-than-normal waist or belly and can make you appear slimmer.
Consumption of water is imperative when using a waist trimmer.
