Jogging a major cause for sagging breast

Millions of women could jogging their way to sagging breasts because they are not wearing suitable bras while exercising.

The average breast weighs between 200 and 300 grams. The movement in exercise puts great stress on the breast's fragile support structure. The outer skin and connective tissues are known as Cooper's ligaments.

Wearing a normal bra only reduces the breast from bouncing by 38 percent, but wearing a sports bra by the firm Shock Absorber reduced bounce by 78 percent.
