Not getting enough physical activity can lead to heart disease—even for people who have no other risk factors. It can also increase the likelihood of developing other heart disease risk factors, including obesity, high blood pressure, high blood cholesterol, and type 2 diabetes.
What happens if you haven't exercised in 20 years?
If you do less exercise or activity you will become deconditioned. Your muscles weaken and lose bulk including the muscles you need for breathing and the large muscles in your legs and arms. You will become more breathless as you do less activity.
Weight brings it's own nasty problems, so a sedentary lifestyle has obvious health risks like obesity, diabetes, high blood pressure, and heart disease. The more weight you gain the harder your heart has to work. Your heart is a muscle, and the less it is worked, the weaker it becomes.
Causes of Physical Inactivity and Sedentary Lifestyles
A poor participation in physical activity is speculated to be influenced by multiple factors. Some environmental factors include traffic congestion, air pollution, shortage of parks or pedestrian walkways, and a lack of sports or leisure facilities .
For example, regular brisk walking can help you: Maintain a healthy weight and lose body fat. Prevent or manage various conditions, including heart disease, stroke, high blood pressure, cancer and type 2 diabetes. Improve cardiovascular fitness.
The most health benefit comes when inactive people become moderately active. Try to work up to 150 minutes a week brisk walking. Making exercise a regular part of your life can have a major impact on your health. The key is to choose activities that involve most major muscle groups (walking, cycling, and swimming).
But is walking good enough exercise? The short answer is yes. “Walking is just as good as any other form of exercise,” says University Hospitals pediatric sports medicine specialist Laura Goldberg, MD. “The guidelines are 150 minutes of moderate activity or 75 minutes of vigorous activity a week.
Exercise intolerance is the reduced ability of the heart to perform activities that involve strenuous movement of your body. It happens when your responses to exercise don't achieve age and gender-appropriate levels.
Where do you start when you haven't worked out in a while?
In terms of frequency, start with a moderate cardio workout three times a week with at least 1 day between each session, and resistance training twice a week, allowing 2 days for muscles to recover. "Rest is part of any workout plan—beginner, intermediate, or advanced," says Olson.
Walking is a form of low impact, moderate intensity exercise that has a range of health benefits and few risks. As a result, the CDC recommend that most adults aim for 10,000 steps per day . For most people, this is the equivalent of about 8 kilometers, or 5 miles.
