Of course, it's no problem to exercise muscles ~ slimming certainly has a certain effect, because you will sweat and drink a lot of water when dancing, which is a good detoxification process! As for local thinness ... it depends on the parts you want to lose weight, for example, the face ... Latin says it has rich facial expressions (whatever you want) ... but it's a little difficult ... but it's like legs (cha-cha, cowboy, bullfighting, which is good for exercising leg muscles), waist (rumba) and buttocks (by dancing samba).
