The classes are a bit daunting, not really a great confidence booster for a first timer in the class, but if you are happy to just go in and get on with it. Don't expect much help from the trainer in there they're just barking out orders. There is a large volume of different types so plenty to choose from. I recommend downloading the app and booking in advance as the popular classes tend to book up.
Of course, the gym does get extremely busy at peak times, but as a 24-hour gym, you can plan your visits to avoid this. This serves as proof of the great value and variety of machines. A timetable of classes are available which range from Circuits to Spinning, and Kettle Bells to the ominously titled Military Body Blast. They are very accessible to view and reserve places on, as each member has their own account on the Pure Gym website. The classes are priced from £1 to £3 and there are up to 10 places available for each class. The smug sense of superiority when booking a 7:30am class is unbeatable. The reality of shivering down to the gym on a dark Winters' morning with a make-up free face and exchanging morning pleasantries with the milkman, is another matter entirely. Needless to say, I only attempted this once and will perhaps try it again in the Summer months.
