A survey of women by the Center for Sexual Health Promotion at Indiana University found that about 5% of women they interviewed had experienced the big “O” while exercising at the gym.  And of those, 40% said it had happened on eleven or more occassions. They are called “core-gasms” because they seem to be related to exercises for core abs, including multiple crunches. But some women had them during weight lifting, yoga, aerobics, and while climbing a pole or rope.  

- No wonder Suzanne Somers always looked so happy in those TV commercials for the Thighmaster! 

- You can tell which women are affected: They’re the ones outside the gym having a smoke with their protein smoothie.
