"A person who gets up in the morning and makes time by spending 30 minutes on the treadmill probably feels pretty pleased with himself -- and he should," Alice Bender, spokeswoman for the American Institute for Cancer Research in Washington, said in a statement.
Nonetheless, "If he's like most Americans, he sits -- on his commute, at the office and at home," Bender said. "So this person, who fits the traditional definition of someone who's physically active, is actually active just 3 percent of his waking day."
Bender suggested getting into the habit of infusing your work day with more activity by:
-- Setting the timer on your computer to remind you every 60 minutes that it's time to step away from your desk and take a short walk down the hall.
-- Getting into the habit of walking and talking.
-- Keeping light hand weights in the office to use while reading e-mail or talking on the phone.
-- During all phone calls and phone meetings, standing up and walking around.
-- Using office or cubicle walls for stretches, vertical push-ups and leg lifts.
-- Asking your employer to put a punching bag or chin-up bar in your break room.
