I've been complaining lately that despite my years of training, with weights, cardio, and yoga, and my general improvement in fitness, I just can't break my threshold in speed and endurance when it comes to running. I've been blaming it on the boobs. I know many of my sister athletes have similar woes, especially we Jewish girls with hearty Eastern European blood. I think there's hope for us though, as evidenced by this article in Discover magazine. Breasts that can fill a D-cup bra can weigh 15 to 23 pounds. Try strapping that much sand to your chest, then running a few miles.
Maybe the next generation of sports bras will help not just 20- and 30-something women who are entering the athletic community after discovering the gym in college, but also girls in junior high and high school whose adolescent body issues (embarrassment over blossoming early and avoiding gym class) prevent them from feeling empowered through sports and general athletic activities. Think of how this could reduce obesity problems in kids and reduce cancer rates in adults.
