Ravi Sandhu, a dance-fitness and IT trainer, uses the 4 stages of competence model to teach dance-fitness to Punjabi music.

His 4 levels build up in complexity and intensity, starting with Level 1, where participants only move their legs, with hands on hips. This allows participants to focus on timing and gradually increase the size of their movements safely. 

Level 2 incorporates hand movements while maintaining low energy. This helps participants coordinate arms and legs. 

Level 3 introduces bouncing, increasing the intensity. 

Level 4 is the highest level of energy and intensity.This model allows participants of various levels, ages, and abilities to participate in fitness.
