Kids, like Ponce de León, need constant supervision while exploring, or they’ll simply vanish into a jungle in search of eternal youth. Keep track of budding gymnasts with today’s Groupon: for $39, you get eight weeks of children’s classes at TIGAR Gymnastics & Cheer in Wheat Ridge (up to a $140 value, including $30 registration fee).

TIGAR Gymnastics & Cheer’s schedule brims with co-ed and single-gender classes for gymnasts of all ages and skill levels. Gymnastic classes (a $110-$140 value), has girls up 4 and older dip their toes into the chalk bag, learn proper techniques, and cover basic skills under the watchful eyes of a coach, while single-gender elementary recreation classes help build kids' self-confidence and strength. Girls progress through three levels, advancing from basic techniques to back handsprings, and in the boys program, leaping lords focus on ring dismounts, handstands, and pommel-horse wrangling in a team-oriented environment. Beyond TIGAR's gymnastics programs, students also perform back tucks and aerials in co-ed tumbling for cheer lessons and practice taming lions with medicine balls during circus arts classes (a $110 value each).
