Christian Rojas acknowledges that nobody has ever seen a sad salsa dancer on the floor. He’s well aware of how all types of dance — and he teaches it all, but specializes in Latin rhythms: salsa, bachata, cha cha cha, mambo, rumba, guaguanco, jazz and hip-hop — affects the chemistry in our bodies. During one of his classes, you can’t possibly frown and dance at the same time. He’s a firm believer that a sure way to bid adios to your woes, increase your metabolism and get in shape is through dance. And he does exactly that by connecting Miami to its salsa roots, with plenty of tumbao, eye-poppin’ accessories and big smiles; SalsaLovers.com.
