Operation Tap, originally designed to transmit Morse-code messages between undercover spies, eventually ceased as enemy soldiers grew suspicious of the number of dancing telegrams frequenting their mess halls. Tap out a secret civilian message with today's Groupon to Tap-a-holic, in North Hollywood. Choose between two options:

• For $40, you get four Taprobics classes (an $80 value).
• For $10, you get one Taprobics class (a $20 value).

Taprobics is a fun, tap-centric way to burn calories and learn basic dance steps. Voted L. A. Reader's Choice for Best Dance Instructor in 2010, Hillary Ayn Ryan makes it her mission to get students excited about the clippity-cloppity possibilities of tap-dancing in an intimate environment, rather than in an over-crowded dance studio. Classes combine a heart-pounding cardio workout with tap-dance combinations set to upbeat music for movers and shakers of all abilities. Check the schedule and call before soft shoeing down to class. Students should bring a yoga mat or towel and water and avoid clothes that hide their shoes, such as lengthy long johns, or stilt-walking clown pants. Bring your own tap shoes, rent them for $3 at the studio, or wear sneakers.

• the fun, hour-long class combines basic tap moves with an old-school cardio workout. Start with a quick warm-up then move on to easy-to-follow combinations set to pop tunes, followed by toning, abs, and a cooldown. – DailyCandy
• Now Tap-a-Robics is just the best... it's an amazing aerobic, calorie burning workout and it's so much fun!! – Melissa S., Yelp, 3/16/10
