Just saw this linked at Dr. Dean Edell's website. Interesting!!!
Exercise Guidelines for Women Established
Apparently the guidelines in use currently are based on MEN. As I've suspected for a LONG time - women ARE different; our fitness levels are lower on average than men's...our capacity declines more rapidly and women whose exercise capacity was less than 85 percent of what it should be were twice as likely to die within eight years.
I'm glad to see that the researchers are focusing on the differences between genders!
