Fitness, gyms, pilates, yoga etc...

Are there any gyms with classes and trainers, similar to Fitness First? The only one I know is Yoga World, but not accessible to men. And for Yoga and Pilates any options aside from Yoga World?

What about personal trainers, bootcamps etc?

Thanking you in advance for helping me in my quest to be fit and thus contributing to my health and longevity ;-p
