Why You Need to Change Your Workout????

How can you tell if an activity is considered moderate or vigorous in intensity? If you can talk while performing it, it's moderate. If you need to stop to catch your breath after saying just a few words, it's vigorous. Depending on your fitness level, a game of doubles tennis would probably be moderate in intensity, while a singles game would be more vigorous. Likewise, ballroom dancing would be moderate, but aerobic dancing would be considered vigorous. Again, it's not just your choice of activity, it's how much exertion it requires.
