He’s one of the most famous bodybuilders in the world.
But when Arnold Schwarzenegger stopped by a gym in Venice, California, this week, he went completely unrecognised – thanks to a nifty disguise.
The 66-year-old muscle man-turned-actor-turned-politician sported a moustache and heavy dark hair in a ponytail under a baseball cap as he completed a day at Gold’s Gym as Howard Kleiner – a fitness trainer and regional manager.

Explaining the reasons for the disguise, Arnold said that he was hoping to promote and also raise money for after school program After-School All-Stars – providing tutoring as well as other activities to those students from families with a low income.
After getting his moustache and fake hair applied, Arnold was ready to take his position at the reception desk of the fitness centre.
And while some gym-goers suspected something was up, others remained unaware that there was a Hollywood superstar in their midst.
Getting started: Arnold then began his day at Gold’s by standing at the reception desk
One man was seen telling Arnie, ‘I forgot my keycard’ – to which the actor replied: ‘What does a keycard mean?’
‘Howard’ then made his way into the gym, where he circulated around those working out to offer helpful tips and advice.
Spotting a man who had worked up quite a sweat, Arnold mopped his brow, telling him: ‘You look like you’re sweating a little bit. Let me just take care of that with a towel.’
One of the funniest incidents in the video, however, was when Arnold stopped a woman at the water fountain.

As she guzzled away on the water fountain, he told her: ‘How are you doing? Taking in a lot of water? That’s good, because remember, 75% of the body is water. So keep drinking.’
Arnold then encouraged the woman to treat drinking water as an exercise, and do it in reps, telling her: ‘Remember we do everything in reps, so you have done 2 reps of drinking water, so you need to do more.’
Correcting her posture and counting her reps up to 10, Arnold then congratulated the woman with a high five, who was completely unaware that she had been the butt of his joke.
Other classic one-liners included Arnold telling a woman doing chest presses: ‘When it burns, it grows, remember that.’

You can do better! Arnold picked on a girl who wasn’t doing her sit ups to his standard
When the lady said he looked ‘familiar in some way’, Arnold quipped: ‘Maybe you saw me on the FBI most wanted list!’
Watching a young woman doing sit ups, Arnold told her: ‘You have elbows and knees, so touch them!’
And Arnold’s tough guy persona continued when he told a man on the treadmill: ‘Stop being a baby. This is Gold’s gym it’s not a baby gym!’

The game was nearly up when Arnold ended his day chatting to a man at reception about protein supplements, with him saying to the actor: ‘Come on, Arnold!’
Cracking the slightest hint of a smile, ‘Howard’ then replied: ‘Howard is my name!’
The video ends with Arnold looking up at a selection of pictures of himself from his bodybuilding days on the wall of the gym, saying: ‘Wow, he looks so good, so handsome!’
Arnold will be matching every dollar donated to After-School All-Stars through Omaze.com, with donors entered into a contest to win two tickets to join the actor in Los Angeles to ride alongside him in his Sherman Tank.
