HOLLYWOOD, Jan. 2 (UPI) -- For those in the mood for a Hollywood-style fitness makeover, a celebrity fitness guru advises improving overall health.

John Spencer Ellis, known as the creator of Adventure Boot Camp for Women -- featured on the U.S. cable TV program "Real Housewives of Orange County" on Bravo -- says it's not just about exercising but the food one eats and the environment in which one lives. For a healthier body Ellis says to:

-- Switch from coffee to green tea for a morning pick-me-up that boosts metabolism.

-- Use a heart rate monitor to take the guesswork out of how effective your exercise routine is and to optimize results.

-- Talk less when working out, too many people lack the focus and intensity needed to reach desired results during cardiovascular exercises.
