Los Angeles – According to femalefirst.co.uk, Dwayne Johnson’s, commonly known as The Rock, personal strength and fitness coach Dave Rienzi says Hollywood superstar never needs to take drastic measures or over-stress his body to obtain a certain look. He said: “We hold his conditioning in a very tight window to allow him to be ‘scene ready’ at any moment. Keeping him at striking distance ensures that we never need to take drastic measures to obtain a certain look, or over-stress his body. The bottom line is that he always needs to be able to perform at his best on screen. The execution of his diet and training needs to be as nuanced and complimentary as possible to allow him to do that consistently.” Johnson was a professional wrestling before entering Hollywood and follows a very strict diet.
