How are calories calculated on the Cubii?

At Cubii, the calorie calculation measures only the calories spent while working out on the Cubii. Cubii calculates these calories by excluding the Basal Metabolic Rate. Each rotation on the Cubii accounts for certain calories spent by the body. The calorie calculations are higher as the resistance and rpm (rotation per minute) goes higher since the body expends more energy to counteract the resistance.
