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.
A "BollyX for 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. Keep your eyes peeled for the release of BollyX for Kids format!
