TWILIGHT STAR PERFORMS THE DEADLIEST EXERCISES ON THE TIP OF A CLIFF

 Someone needs to tell Kellan Lutz he's not really a vampire bat.

The Twilight star posted stomach-lurching pictures of himself on Wednesday doing exercises on the tip of a cliff overhang.

The 30-year-old pulled a handstand and even hung off the underside of the precarious-looking rock jutting out over Palm Beach hundreds of feet below.

'I was able to fit in a quick workout while we were exploring these cliffs,' he wrote in the Instagram caption.

'I did 20 push ups & 20 pull ups, but don't try this workout at home. Man, Palm Beach is stunning! #WorkoutWednesday'.

The 'push-ups' he does are with his feet suspended in mid air, and he wears no ropes or safety harness, meaning one small slip on the precipice would spell the end of the adrenaline junkie.

But he doesn't look worried, beaming happily as he performs the death defying stunts.

Earlier the super-fit star posted another extreme workout pic, although this one had a significantly reduced chance of death.

While regaling his 494,000 followers about the history of Barrenjoey Lighthouse, the American hunk pulled a handstand on the sandstone block parked in front.
