Don't have time for a full 60-minute workout? Don't sweat it. Divide and conquer. Shorter bursts of exercise, such as short walks spread throughout the day, offer health benefits too. Whether you're trying to lose weight or improve your cardiovascular fitness, the key is to get moving. Take the stairs, walk during your lunch break, and do household chores at a pace fast enough to get your heart pumping. It all adds up!
