Energize Health Club

Definitely on the smaller side when compared to the larger commercial gyms like Virgin or Fitness First. However, having said that, they do have amazing friendly staff there and an excellent range of trainers. Wonderful people and when you go outside of peak hours, there's plenty of equipment to use. Plus they have squash courts (free hire before 5pm) which is a bonus.

Good small family owned gym as long as you go out of peak times. Limited classes and opening hours. But if you just want a place to quietly work up a sweat and are not a gym junkie who needs to work through a specific workout each visit, then this could work for you.
