Quoting Costas Karageorghis, deputy head of research at the School of Sport and Education at London’s Brunel University, the April 2, 2013 Wall Street Journal says workout music between 125 and 140 beats per minute is best to boost stamina and motivation. Of the 17 couples dances that Wilddancer covers today, for which the standards federations or experienced teachers give tempo ranges, 7 of them are in this range, 6 are slower, and 4 are faster. Given our focus, we’d say that all 17 are fine for motivation because they are fun. Officially slower ones such as the (slow) waltz and the bolero are more romantic than fitness-producing, but samba, hustle, and polka are energetic … at least as measured by the sweating and shortness of breath they produce. And the faster ones–quick step, Viennese waltz, salsa/mambo, and country two-step generally use songs of shorter duration (except many salsas are long … maybe a measure of macho for male dancers).
