Cardio for Health and Weight Management
The Stronger By Science Podcast
The Health Benefits of Physical Activity
Stronger by Science is a weekly podcast from CNN.com and the iReport network. This week, Jarrett Bellini looks at ways to increase your physical activity without committing to a structured exercise program. He also talks about what he calls "exercise snacks," an extremely small portion of exercise that should be done with high frequency throughout the day.
In today’s episode, Eric takes a comprehensive look at how physical activity and cardiovascular exercise can impact general health and weight management. Specific topics of discussion include non-exercise physical activity, exercise snacks, step counts, appetite, exercise energy compensation, interval versus steady-state cardio, the interference effect, and practical ways to incorporate non-exercise physical activity or structured cardio into your daily or weekly schedule.
