While there are no hard and fast rules for how long you can wear your waist trimmer every day, you can wear it quite a bit. The first week, it’s best to stick to only two to three hours a day and gradually move the time up as the week’s progress and you get used to the belt being around your waist.
As with anything else, the actual time that you can wear your waist trimmer for depends on the specific person and it is best to consult with your primary care provider to determine whether what the best length of time is for you.
