The southgate gym is very cheap, youhave instructors there who’ll give you a program to do as often as you want at the time that suits you and they have all kinds of equipment. They also do some classes.
Same for Bettystown court plus you have the pool great for kiddies, a bit more expensive but still great value, 13 months for 12 and it’s about 350/year (kids free on adult membership).
Both are open all day without lunch break (can’t remember opening times, but quite wide)
