Jamie Dornan's fitness trainer recently shared how she helped the actor stay fit and healthy while he was filming "Fifty Shades of Grey," "Fifty Shades Darker" and "Fifty Shades Freed."

According to Ramona Braganza, exercise should always be paired with proper nutrition. When it comes to Dornan, Braganza said that the actor went on an 80:20 kind of lifestyle which means that all of his food and alcohol consumption was cut down. The trainer added that 80 percent of Dornan's time was focused on working out and dieting, while 20 percent is when he could go on cheat days.
