Olivia Munn was hypnotised into enjoying the gym.

The 'Magic Mike' actress was not a fan of keeping fit but after being told it would improve her anxiety by her hypnotist, who treated her for obsessive compulsive disorder and trichotillomania - compulsively pulling out her hair - agreed to let him try and refocus her consciousness in the hope it would increase her motivation.

She said: ''I was going to a hypnotist to help me with my OCD and trichotillomania. One day I told him I didn't work out, and he said, 'What do you mean?' I replied, 'I don't know. I just kind of don't. I yo-yo.' He said, 'You have to! It's good for your anxiety and depression.' So during one of our sessions, he hypnotised me.''

And the 35-year-old beauty - - who is dating American soccer player Aaron Rodgers - was stunned to find the results were instantaneous.

She told Good Housekeeping magazine: ''I'm not exaggerating: That was on a Friday, and by Monday I was working out every day at 6 am.

''If I missed a session, I'd double up and do it the next day. Now I feel so much stronger. I remember running up the steps one day and thinking, 'This is strange. I could do this a hundred times and be totally OK.' ''
