The Body Braid is a posture support and trainer. The straps reinforce the function of our internal connective tissue (tendons and ligaments.) It supports the shoulders back and down in their most stable and strongest position while still allowing full range of movement. This is something that benefits most of us who have developed posture habits of shoulders rolled forward. The Core Braid is the core of the Body Braid system and it supports our body's core, including shoulders, back, ribs, pelvis and hips.
