Men's Guide
If you supplement your regular lifting routine with yoga classes, you’ll be able to activate ignored sections of muscle. For example, take the serratus anterior or “boxer's muscle,” which is located under your armpit and over the side of your ribs. This muscle provides stability for your shoulders and is a base for developing deltoids and pectorals. Making your serratus anterior pop will help your abs look ripped, and you can get at it with yoga.
