The HBP waist trimmer belt is designed to draw in and support your belly so that you can be aware of those muscles and hold them in on your own when you're not wearing it. Some say wearing one while working out and sweating will trim your waistline, but we know that hard work does that. The extra support of the HBP waist trimmer makes it a good option to wear during the day to keep your tummy tight and your posture on-point.
The Medium Size will fit up to a 48" waist.
Do NOT use it if you are allergic to Neoprene.
