The first thing you need to do is make sure that you have the right size. Better Breathing Sport comes in three sizes: small, medium, and large. To find the right size for you, simply measure your chest circumference. If your chest circumference is less than 34 inches, you should order the small; if it’s between 34 and 38 inches, you should order the medium; and if it’s 38 inches or more, you should order the large.
Once you have the right size, it’s time to start using Better Breathing Sport. To get the most out of the product, you need to use it for at least 20 minutes a day. The best time to use it is after a workout, when your muscles are warm and your body is relaxed.
