"This sweat belt really makes me sweat during cardio. The zipper is sturdy and it's easy to adjust. I can feel the heat around my core right away. Comfortable enough to wear while running or doing housework.”

"Love that this has a zipper instead of just velcro. Much more secure and adjustable. I wear it while walking on the treadmill and it definitely increases sweat in my stomach area. Not too bulky under clothes either."
