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 to attend adult group fitness classes with the supervision of the parent, they can take BollyX.
A kids format is currently in development by the BollyX team that is 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.
