As is known, dance can burn as many calories as walking, swimming, or riding a bicycle．During a half hour of dancing you can burn between 200 and 400 calories．How many calories you'll burn is determined by the distance you travel．We've found it quite possible for a dancer to cover more than a mile at a brisk pace in a single evening of dancing．
Regular exercise can lead to slower heart rate and lower blood pressure．Experts typically recommend 30-40 minutes of continuous activity three or four times a week．Dancing may not provide all the conditioning you need, but it can help．The degree of cardiovascular(心血管性的)conditioning depends on how vigorously(精力旺盛地) you dance, how long you dance continuously and how regularly you do it．Besides, the side to side movements of many dances can strengthen your weight-bearing bones and can help prevent or slow loss of bone mass from osteoporosis(骨质疏松)．On the other hand, dancing contains a social tie that solitary fitness endeavors don't．It gives you a chance to develop strong social ties, self-esteem and a positive attitude．So why not join us right now and experience the best part of life tonight?
