We recommend starting off with wearing your trainer for three to six hours a day, gradually increasing the wear time for maximum results. Listen to your body! Wear it as much as you can, taking care not to over-exert yourself and be certain you are never compromising your breathing. Starting off small and upping your wear time gradually is what will ensure your safety, as well as allow you to reap the best, most efficient results that you will be able to maintain long-term.
