                                For his role as Superman in 'Man of Steel,' Henry Cavill trained for approximately 11 months, achieving a body fat percentage reportedly as low as 7% during peak condition. This physique makes a standard BMI calculation, like the one used to determine what is Henry Cavill's BMI, highly misleading.
