"Don't use your back like a crane"...went the public health messaging in the 80s.
It was aimed at making us all think about how we were lifting - from the legs, not the back.
Someone who's done more than his fair share of heavy lifting is Richie Patterson.
He won gold at the 2014 Commonwealth Games in Glasgow, silver in Delhi in 2010.
He also competed at the London and Rio Olympic Games.
He now runs a company called Manual Handling, which goes into workplaces teaching people to avoid sprains and strains and shares his expertise.
