Ex-forces personal trainer Jack Johns, 47, is scaling buildings, lampposts and even diggers to carry out press up challenge.

A Bideford personal trainer has taken a Facebook challenge to new heights – scaling lampposts, buildings and even road signs to do press ups.

The ‘22 for 22’ challenge has been sweeping social media and sees people spend 22 days doing 22 press ups to raise awareness of post traumatic stress disorder (PTSD).

But Jack Johns, 47, who spent 25 years in the Royal Logistic Corps as a physical training instructor, decided to step the challenge up a notch.

A keen climber and free runner, the father-of-two from Bucks Cross has been attempting his 22 daily press ups on top of diggers and goalposts, hanging upside down from cliff faces and on police car bonnets.

Unafraid of heights, Jack has even scaled a lamppost, large road sign and prominent buildings – but warns others not to copy the daring trend to that extreme.

“I have been climbing my whole life and I’ve only done what is within my ability and I know I can confidently do,” said Jack, who now works at G4 in Bideford.

“I have close friends who have suffered PTSD and I wanted to join in this challenge to help raise awareness as it’s an issue very close to my heart.

“When I was younger, mental health was a taboo subject; it was never brought up or mentioned, so it’s great how this awareness has now come about.”

Jack has now finished his challenge, but said he may release a couple more videos as he wants to reach 22,000 views – so far he has reached 19,000.

“I’ve had messages of support from strangers and people all over the world have seen my videos, it’s incredible,” he said.
