If you're looking for luxurious extras, this isn't your place – The Gym has no pool, spa or holistic juice bar. What it does offer, however, is 24-hour access to excellent fitness equipment at rock-bottom prices (one-day membership is £5; monthly membership comes in at just under £20, no contract required).
The modern basement space is accessed via a personal pincode and a futuristic space pod entry system, and it can get busy at times (the weights section is regularly taken over by men apparently competing for strongest man of the year). That said, there are perks aplenty – including a range of free classes, from circuit training to boot camp. The Gym has several other branches across London, some of which have monthly memberships starting at a mere £12.99.
