Punjabi music and movement show up in at least four distinct contexts, and Pungra deliberately specialises in only one of them — much like running covers everything from jogging to sprinting, or swimming covers everything from a fun paddle to competitive laps, dancing to Punjabi music covers more than one activity, even though "bhangra" often gets used as a catch-all word for all of it:
Moving to Punjabi music — the oldest root, meditative and devotional.
Celebrating to Punjabi music — the wedding floor; spontaneous, social, no instructor or qualification needed.
Performing to Punjabi music — the stage; a legitimate trade built on years of artistic training.
Exercising to Punjabi music — structured fitness, led by a qualified instructor, with participant health as the goal. This is the one Pungra specialises in.
None of the four is lesser than the others — they're just different activities that happen to share musical roots, and conflating them is where most confusion (and most low-quality "bhangra fitness" classes) comes from.
