Neither jazz dance nor belly dance can lose weight.
Jazz dance is a kind of street dance, which consumes a lot of energy. The more you practice, the hungrier you get. Just keep fit.
In belly dancing, thin people are not good-looking at all. To be an authentic belly dance, you must have a little feeling of belly dance.
If you want to learn to dance, your 18 years old is in love! Who has the foundation of learning? Everything starts from scratch!
Lose weight! Jump rope! Can be increased!
