Weekend multi sports in or around Cambridge

[MyBoysHaveDogsNames]

Hi

I'm looking for a session for my 10 year old son at the weekend.

He's not really into team sports but I'd like him to do something to keep fit.

Has anyone any ideas of fun, non-competitive sessions or of other activities he could try?

Thanks

Gymfinity Ninja school? Cambridge Kung Fu? Climbing? Diving?

I think there's roller skating at Chesterton Sports Centre on a Saturday afternoon.
