There's a new way for Londoner's to keep fit, as long as you're over 60.
London's first "pensioners playground" has been given the go ahead to open in Hyde Park, it'll have things like a cross-trainer and bike, and is for elderly people to get gentle exercise without having to go to a gym.
Although Westminster Council says it's not going to bar younger people from giving it a go either.
The playgrounds are already really popular in places like China.
