One of the earliest sports parents can enroll their young children in is toddler tumbling, with some classes accepting children as young as 18 months. The Woodbridge Academy of Gymnastics states that gymnastics is one of the most popular sports for children, citing how it teaches "strength, balance, coordination and team spirit." Even those who don't actively participate in gymnastics are drawn to the grace and skill displayed by gymnasts. Statistics collected by Topend Sports show that gymnastics was the fourth most talked about Olympic sport on Twitter during the 2012 Olympic Games. 
Although acrobatic gymnastics is not an Olympic sport, USA Gymnastics reports that it is growing in popularity. In acrobatic gymnastics, competitors must perform a balance segment, in which they hold complex poses to demonstrate flexibility and balance, a dynamic segment, where they demonstrate power and grace with throws and flight, and a combined routine, according to the International Gymnastics Federation (FIG). In the video below, taken at the 2010 Acrobatic Gymnastics World Championships held in Poland, the team from Russia shows off its mastery of these skills along with playful choreography that belies the focus and precision required of the routine. 

The confidence and grace these gymnasts show between moves and throws is astounding. Not only must each girl have incredible control over her own body, she must also implicitly trust her partners. One slip from any member during a pose or throw could result in a grave injury. Yet with no hesitation, these girls hit every mark perfectly. Not surprisingly, the team took first place for the Women's Group, Combined competition. The video, uploaded by gymnastics fan Brian Kincher, has received over 6 million views since it was uploaded in November 2013.
