K-pop dances. Alot of them are tons of fun, it doesnt matter that you may or may not be a great dancer, all that matters is that you reach your goal.
Since all the weight is in you legs, alot of K-pop dances use alot of the calves and upper leg areas, so alot are good for workouts. And the ones that dont use alot of those areas are acutally good for workouts too.
The one that comes to mind is Breathe by miss A. It's tons of fun, and easy but very tiring but worth it.

Another one is Lucifer by SHINee. Even though it has tutting and popping here and there, it's great for a workout.
