BollyX and BollyX LIT was designed for adults 18 and older. It's a group exercise class taught at gyms for adult members. Having said that, if the gym allows teenagers age 13-17 to attend adult group fitness classes with the supervision of the parent, they can take BollyX as long as their parents are present.
There is a "BollyX for Kids" format appropriate for those ages 4-7 and 8-12. It'll have choreography, games and music that is selected and geared towards those age groups. This format was launched May 2018. Check the website to search for BollyX for Kids classes in your area!
