More U.S. adults are getting physical - or at least that's what they're telling researchers. A national telephone survey found the percentage of women who report regular physical activity rose to about 47 percent in 2005. That’s up from 43 percent in 2001. The percentage of men reporting regular exertion rose to about 50 percent, from 48 percent. However, U.S. obesity rates are not declining, and there are indicators that some weight-related conditions - such as heart disease - are getting worse in some adults.
