well you said reasonable, which really takes a lot away! lol.
the gyms here are NOT like US ones, i've been to some of the 'nicest' in london and they don't hold a candle to the ones i've belonged to in the states as far as facilities and cleanliness.
Holmes place are OK
We have a leisure center near us associated with our council. it has a pool, work out room etc and only costs us about 2 quid a use...that is...as soon as we try it.
it's something to look into, but holmes place was OK but i couldn't see paying 85 pounds a month. a bit much.
