Before radio, music was broadcast via Morse code, which turned everything into a treble-heavy dance music punctuated by demands to STOP. Limber up for more graceful dance moves with today’s Groupon: for $39, you get a five-week beginner dance-class series plus one drop-in dance fitness class at Dance 4U (an $85 value). Today’s deal is redeemable at the Dance Centre, Alpen Club, and Creekside Community Recreation Centre locations.

Dance 4U’s expert instructors guide students of all experience and ability levels through an array of dance and fitness classes. Five-week beginner classes encourage nascent rhythm-whisperers to exercise muscles as they develop the fundamentals of the dance style of their choice, including swing, salsa, and freestyle Macarena. Prancing pedagogues acquaint rug cutters and their internal metronomes with the jazz-laced “6-count” during the beginner swing class and school feet on basic steps. Treat swivel-hungry hips to mesmerizing Latin moves in a beginner salsa class that teaches musicality and basic footwork at a moderate pace. Though attending classes with a partner or ball gown–clad mop is recommended, students need not worry about showing up solo, as partner rotations occur during each lesson to encourage a social atmosphere.

Hoofers can whip physiques into toned machines during a drop-in fitness class. Pupils shimmy through a combination of core conditioning, calisthenics, and choreography in salsa dance fit, or sweat out the song stuck in their head during dance boot camp.
