The topic of physical activity has made a lot of headlines lately, with some questioning if you need to take that brisk walk or bike ride to help you lose weight. It’s an important area of research but as it continues, one point is getting lost: for lower cancer risk and overall good health, the research is strikingly clear: being active matters.
Research shows that being active lowers risk for three cancers – endometrial, colorectal and postmenopausal breast. That lower risk comes independent of weight.
And while what you eat plays a key role in weight loss, that daily walk can make a difference. It also helps with weight maintenance. That 30-minute brisk walk can still burn off your morning yogurt (about 130 calories).

Both lab and human research point to several ways in which regular activity may lower cancer risk, including:
Physical activity also plays a critical role in many other areas of health, such as:
Are you active enough? Take our quiz and see.
AICR recommends that you aim for 30 minutes or more of moderate activity every day. Exercise for longer, such as 60 minutes a day, and the benefits increase. If you’re strapped for time or your just starting out, aim for bouts of 10 minutes at a time.
Government physical activity recommendations add that you lift weights, or do other muscle-strengthening activities two or more days a week. These exercises can help you minimize bone loss, and improve strength and balance.
