Attention weekend warriors: the simple act of exercise and not fitness itself can convince you that you look better, a new University of Florida study finds. People who don't achieve workout milestones such as losing fat, gaining strength or boosting cardiovascular fitness feel just as good about their bodies as their more athletic counterparts, said Heather Hausenblas, a UF exercise psychologist.

The University of Florida will receive $29.5 million in federal stimulus funds over the next two years from the National Institute on Aging to begin a six-year study on whether a program of structured physical activity can prevent or delay major movement disability in older adults. When completed, funding for the project is expected to total more than $60 million from the NIA, including the $29.5 million through the American Recovery and Reinvestment Act of 2009.

A regular tai chi exercise program can help people better control their diabetes and lower glucose levels, according to a University of Florida study.
