Arnold Schwarzenegger tells online forum users to 'behave and stop bickering'

Arnold Schwarzenegger has stopped into a cardio workout forum fitness thread to terminate a dispute about workouts.

Users on the forum had been at odds as they responded to a post called "Best Damn Cardio Humanly Possible in 15 Minutes", the Independent reported.

The former professional bodybuilder urged Reddit users to behave and stop bickering.

He wrote that it is about inspiring more people to get into fitness and he has never understood people who argue constantly about who is wrong and right.

The contribution was quickly voted to the top of the post.
