Like defusing a bomb, a well-executed dance routine requires concentration, skill, and a nervous partner who questions your every move before unexpectedly jumping out of a window. Blow onlookers away with explosive dance moves with today's Groupon: for $35, you get five dance classes at Gus Giordano Dance School (a $75 value with processing fee).

Established in 1953 by the American jazz-dance legend Gus Giordano, the new school was reopened in June 2011 by Giordano's daughter Amy, and motion-filled bodies continue to tap and tiptoe through a multitude of classes. Led by Amy Giordano and a stellar cast of gravity-defying daredevils, Gus Giordano Dance School exposes fumbling feet to a wide array of skeleton-grooving sessions. Learn time-honored tactics such as the Giordano jazz technique, which uses isolations, floor work, and movement combinations, or floor barre, which solidifies prima-ballerina placement by practicing ballet work on the floor, instead of in the traditional vortex of space. Fitness classes such as Zumba loosen limbs, and the hip-hop class introduces dance combinations to extremity movers with age-appropriate music and padded practice grillz.

With no more than 25 balancing bodies in each class, enough space and personal attention are ensured for each dancing daisy to polish the hardest of techniques, such as split center leaps and belly-rubbing, head-tapping fifth positions.
