Gym CCTV shows why you should never remove a jumper while being on a treadmill
British man Adam Skelton (30) decided that after three years it was time to start working out again, and so he decided to go to a gym.
As a warm up Adam decided to pop on the treadmill for a few minutes, before he got too warm and decided to remove his jumper.
"Forgot I was on treadmill for a second", Adam wrote on Facebook, where he shared the video.
The clip shows him create a trail of destruction, as he falls backward and into the person behind him.
Thankfully the pair can be seen getting up and shaking hands, without appearing to be seriously hurt.
