According to Fitness Blender, playing "Just Dance" for half an hour burns about 200 calories, although it also notes that the exact number of calories burned in play varies with the weight and sex of the person playing.
It is possible to choose songs that increase the number of calories burned while playing. Songs ranked with only one sweat drop burn about 18 calories, and songs ranked with three sweat drops burn about 23 calories. Fitness Blender also recommends exercising between songs by doing sit-ups, push-ups or jumping jacks, as a way of burning even more calories.
Male players typically burn more calories while playing "Just Dance" than female players. In addition, players weighing more than 130 pounds on average burn more calories than those with lower body weight.
