How to Live Longer and Lose Weight By Exercising

After you subtract all of the commercial time, the average half-hour sitcom only runs for 20 to 25 minutes. That's the same amount time you should walk each day if you want to add up to seven years to your life, scientists say.

If that doesn't inspire you to turn off Netflix and get moving, we're not sure what will.

To come to this finding, German researchers had study participants between the ages of 30 and 60 take up various fitness regimens. Then they collected blood samples to measure the participants' aging progression. Six months into the study, the research team found that all of the participants had increased levels of DNA-repairing enzymes. They also had fewer biomarkers of aging. In other words, their fitness regimens slowed the aging process.

"We may never avoid becoming completely old, but [this study shows that] we may delay the time we become old," study author Sanjay Sharma explained at the European Society of Cardiology Congress. "Exercise buys you three to seven additional years of life. It is an antidepressant, it improves cognitive function and there is now evidence that it may retard the onset of dementia." Sharma went on to say that exercise is beneficial for people of all ages and recommends that everyone walk for 20 to 25 minutes a day. Prefer a more intense workout? The study also showed that high-intensity interval training (HIIT) could be just as effective. However, they found that strength training — though an important part of a well-rounded fitness regimen — doesn't slow the aging process as effectively as other forms of exercise.

Eat This! Tip

Hate the gym? Don't sweat it. With some planning, it's easy to fit 20 minutes of walking into your daily routine. If you take the bus or subway to and from your office, for example, get off one stop early and walk the rest of the way. Travel by car? Park at the far end of the parking lot to get in some extra steps before settling in at your desk. If you work in a highrise, take the elevator half the way up to your office and then switch to the stairs.
