Gym central London , for families

[Bauble74]

I would like to join a gym in central London, preferably on a tube/train route that goes to kings cross. I would like a pool, yoga and spin classes that I can use after work. I also would like to take dc at the weekend to swim.i probably need a David Lloyd/ virgin type one but am just wondering if there are any others out there ?I live outside of London but don’t have anything suitable in my area. If it had an outdoor pool, that would be amazing but I’m probably asking too much.

There is a better gym/outdoor pool called oasis near Holborn.

Thanks Superram, I have been to that one but I wasn’t keen on it, too packed and seemed a bit dirty. I may have just caught it on a bad day though.
