Sports Bra Band Support Foundation Principle: How Band Structure Anchors Your Movement
Look for bras with wide straps, a rigid band, and molded or underwired cups that lock the breasts firmly against the chest wall to prevent the painful "eight-shoulder" motion associated with intense movement. Subtract the band measurement from the bust measurement; the difference in inches determines your cup size (1 inch = A, 2 inches = B, 3 inches = C, etc.
The band, which sits horizontally under the chest, provides the majority of the hold, anchoring the bust to the body. Low-impact activities like yoga or walking involve minimal bounce, allowing for softer compression styles or lighter encapsulation.
