The swimming lessons are £62 for ten, which I thought was ok and I have learnt to swim from them. The private lessons were an awful lot more. However, offering free classes would be a good way to get people more active.
I think delivering free swimming and gym is really expensive and I'm not expecting it to happen soon. However, it shows a commitment to getting people fit and that's so important. I suspect the comments people have made are right and it will end up being limited free acess, but I think that's still better than nothing.
