New Delhi, July 25 - He is six-foot-four-inch tall and a nine-time world wrestling champion, but contrary to his action image, Dwayne Johnson alias 'The Rock' loves acting in family entertainers like his latest film 'Race to Witch Mountain'.

So despite being an action figure, Johnson has featured in many humourous movies like 'Southland Tales', 'The Game Plan', 'Get Smart' and 'Be Cool'. And he credits his movie picks to his seven-year-old daughter.

'I recognised the importance of having a movie that the entire family can see. Being a dad made me understand how important and valuable it is to have really good family films,' Johnson said in an e-mail interview to IANS.

But body building is still close to his heart and he follows a strict fitness regime to maintain his huge build.

'Training is always important to me, it is the foundation of my lifestyle and the anchor of my day. I get up very early at 3.45 a.m. and I'm out of the house by 4.45 a.m. and usually training by 5 a.m. I train until 6.15 a.m. and then I'm on the (movie) set by 7 a.m.,' Johnson said.

'My workout is my cup of coffee in the morning, my sanctuary. I do a lot of cardio...I keep that consistent, because I like having my heart rate between 120 and 130 for the entire hour and 15 minutes. I combine cardio with resistance training, weights and core training. It is all non-stop and the goal for me is to challenge myself every day with different workouts,' added the wrestling champion who weighs 102 kilos.

Johnson, who made his big screen debut in a cameo in a 2000 teen movie, 'Longshot: The Movie', follows a simple diet regime.

'My diet is simple and very clean. I stay away from fried foods and fast food. But every third or fourth day, I do give myself the opportunity to completely gorge and I indulge in a little gluttony. I eat pizza or whatever I feel like.
