To date the ISDF has been granted full recognition by the International Olympic Committee as the worldwide governing body for DanceSport and the USABDA has been granted affiliate membership recognizing them as the national governing Body of DanceSport in the Untied States. The last remaining step is for DanceSport to be granted Program Status by the IOC at which time DanceSport would then be added to the Olympic program. Although the cost depends on the particular institution, ballroom dance classes offered here are usually very inexpensive or free. A good way to keep cost at a minimum is to share your dance lessons with a friend or partner. Even if you do not have a partner to attend ballroom dance lessons with, most classes will pair you up if you are single. Whether you are dancing a slow dance such as the waltz or an upbeat dance like the jive, you need to choose attire that you can move easily in and won't get tangled up around your partner. For example, consider choosing a dress made of silk; it flows easily and doesn't tangle. Remember that although ballroom dancing is a formal and elite event, your dress doesn't have to be covered in heavy sequins, jewels, or feathers. Men often wore their swords while dancing with a woman and it is believed that this led to a woman placing her left hand on her partner's right shoulder, while grasping his left hand for additional balance. This is also where the concept of men leading on the dance floor was developed. As time passed throughout the centuries, many styles of ballroom dancing were born. Unfortunately, some people continue to live inactive lifestyles because they just can't find a physical activity they like to do. You may be surprised to learn that ballroom dancing can burn just as much fat and calories (if not more) than a session at the gym. Depending upon the style of dance, you can easily burn between 200 and 400 calories. Because the Argentinean Tango doesn't require a great deal of movement it is well suited for nightclubs and other places with small dance floors. Unlike the Waltz, the sway and the rise and fall motions are to be avoided at all costs. The desired movements are very sharp and well defined. The music for this ballroom dance is usually provided by an orchestra that has a piano, guitar, violin, flute and a bandoneon (an offshoot of a koncertina, which looks a little like a small accordion).
