Before starting Pungra certification, you'll need:
Exercise to Music Level 2 (or equivalent), roughly 80–120 hours of study. UK providers include YMCAfit, Train Fitness, and Future Fit — look for Ofqual accreditation.
CPR and First Aid certification.
Public liability insurance, minimum £6 million, valid specifically for fitness instruction.
A music licence, if you plan to play recorded music to a paying audience.
A DBS check, if you'll be working with children or vulnerable adults.
Once these are in place, Pungra certification itself is free.
