Is it exercise?
Once you get to the point where you're getting your heart rate up, you're actually getting a terrific workout!
Dance is a weight-bearing activity, which builds bones and is also wonderful for your upper body and strength.
Would-be dancers should consult their doctors first, particularly if you have any health problems. How many calories will you burn? That depends on your body and how vigorously you dance.Dance is considered to be a "moderate activity," of which the USDA's physical activity guidelines says adults should get at least 30 minutes of every day.
New ballroom dancers may feel muscles they didn't know they had. Ballroom dancing often means moving backward, especially for women. That's very different than walking forward on a treadmill or taking a jog around the neighborhood. Ballroom dancing works the backs of the thighs and buttock muscles differently from many other types of exercise. The legs and arms often do the flashy dance moves. But they're sunk without a strong core.The "core" muscles -- the abs and back -- are used a great deal in ballroom dance.
Dance can challenge your mind as well as your muscles! An observational study has shown ballroom dancing to reduce the risk of dementia compared with those who rarely or never danced. Of 10 other physical activities considered in the study, only dancing was tied to a lower dementia risk. How might ballroom dancing help the brain? Three possibilities have been identified: Increased blood flow to the brain, a decrease in stress, and the mental challenge of memorizing steps and working with your partner.
