(HealthNewsDigest.com) - You probably know that regular physical activity is an important part of a healthy lifestyle. It lowers your risk of chronic health conditions such as heart disease, stroke, high blood pressure, obesity, diabetes, depression and some cancers. But what exactly is physical activity? Is it the same as exercise? And how do you know if you're getting enough?

Physical activity is movement that works your muscles and requires more calories than you use when resting — such as gardening, taking the stairs and dancing in your living room.

Exercise is a structured and repetitive form of physical activity that can improve your cardiovascular fitness. It includes activities such as swimming laps, taking a brisk walk, stretching and strength training.

For the best health benefits, it's important to combine physical activity and exercise each day. Aim for achieving 30 to 60 minutes of moderate-intensity physical activity — including structured exercise — most days of the week.

Physical activity is most beneficial when it's intense enough to really boost your heart rate. Focus on moderate- and vigorous-intensity activities, such as washing your car, mowing your lawn with a push mower or biking with your kids.

Choose activities that you enjoy and can do regularly. By performing an activity or exercise for even just 10 minutes at a time, you're gaining the health benefits of physical activity. Consider these ideas:

• Do your desk work standing at a counter.
• Exercise while watching TV. Start with commercials.
• Vacuum your carpets and furniture.
• Wash your floors.
• Wash your windows.
• Turn off your TV and take a walk.
