Why Swimming is good for Women

2 words. Pectoralis major.

Even if you don't want to develop pecs that can jerk up and down like those bodybuilders can, swimming the usual front crawl, backstroke and breaststrokes can keep your boobies from sagging, and ever perky and firm =D. I usually do at least 5 laps of backstrokes when I swim.

I saw it on a South Korean tv programme, and the man had bigger breasts than everyone in the audience *hahaha*.
