This is the shocking moment a gymgoer accidentally tipped a barbell, sending its weights crashing onto a passerby.

CCTV footage captured the teenager unloading iron plates from one end of the barbell at a fitness centre in Inner Mongolia, China.

As he removed the second weight, the unbalanced metal bar suddenly flipped off the rack and slammed into the shoulder of the man walking nearby on July 21.

The victim reportedly did not sustain serious injuries.

He said: ‘The boy wasn't a staff member; he had just joined the gym and was unfamiliar with safety procedures.

'After the incident, he immediately checked on me and even contacted his parents to help with my shoulder and arm injuries. He was very sincere and responsible.

‘Since my injuries weren't serious, and considering the boy's lack of experience, I decided not to take further action.'
