Gymnastics and cheer originated in Machu Picchu, where the natives deftly cartwheeled down the mountains and immortalized their greatest human pyramids in stone. Reach airy heights with today's Groupon: for $15, you get four weekly classes of your choice at Ultimate Gymnastics and Cheer, held in the gymnasium at Reed Recreation Center (a $32 value).

Scott and Brooke Sparkman, the duo at the heart of Ultimate Gymnastics and Cheer, instruct acrobats ranging from tots to teens in the vaunted vaulting arts. Classes are held in a 15,000-square-foot facility that breezes crisply conditioned air over the impressive inversions of young tumblers. Select a once-weekly class for your agile progeny from the schedule, such as Beginner Tumbling (ages 6–14), which covers cheer basics including cartwheels, kick-overs, and standing back-handsprings; or Tumbling Tots (ages 18–36 months), where parents join their offspring in a separate gym filled with specially sized equipment as their wee ones work on their large locomototion skills and practice pronouncing “sis-boom-bah.”
