Dwayne Johnson

Dwayne Johnson was arrested "eight or nine times" by the time he was 17 after being involved in a theft ring.

The Hercules star had a tough upbringing in Hawaii during his teenage years and after getting evicted from his apartment aged 14 he turned to crime and used to be part of a group who would target tourists.

When asked what the group were looking for he replied: "High-end clothes and jewellery. In Waikiki there's a couple high-end blocks where there's your Prada, Chanel, Gucci, Armani, jewellery stores, plenty of jewellery stores. There are a lot of tourists that come into Waikiki and there's a lot of money. A lot of foreign money that comes in, and we were part of a theft ring that would target those groups. We would target the money, we would target the high-end clothes and we would target the jewellery - turn around and sell it, best we could."

muscle-building

While he was in trouble with the law at times, the star turned to muscle-building at age 14 to help him get over the pain of being evicted and admits it helped to a certain extent.

He added to Muscle and Fitness magazine: "At 14 when I started training, at 14 is when I also started getting arrested for fighting, theft, all kinds of stupid st that I shouldn't have been doing.

But, I still found time to go to the Boys Club every afternoon to hit the speed bag, hit the heavy bag, hit the iron. I was building my body because again, it's that eviction mentality. But, I would get in trouble and get arrested. I got arrested eight or nine times I think by the time I was 17."

The 42-year-old star also credits his muscle-building activity for helping him to deal with his depression.
