Salsa [pictured] is an energetic Latin dance, associated with the music genre of the same name, which was first popularised in the United States in the 1960s in New York City. Salsa is an amalgamation of Cuban dances, such as mambo, pachanga and rumba, as well as American dances such as swing and tap. It was primarily developed by Puerto Ricans and Cubans living in New York in the late 1960s and early 1970s. Cardio salsa is a high-impact fitness routine that uses salsa dancing to keep the heart rate elevated at the same level it would be during jogging.

It is never said where Lorelai got the cardio salsa tape that she shows Rory, but it’s interesting that Rory bought Michel a cardio salsa tape for Christmas in 2000 (Season 1). Has he re-gifted it to Lorelai? Rory never says that she recognises it, but she certainly doesn’t seem impressed.
