Interesting article in the Guardian hereabout the booming 24-hour gyms popping up everywhere. The article features The Gym at Vauxhall's St George Wharf - very popular with London's gay men looking to get club fit.
Weird things about The Gym in Vauxhall:it's the only gym we've ever seen people pop out for frequent cigarette breaks. An instructor also told us that some folks often take G to exercise which they don't encourage. It's rammed most hours with long queues to get in and out at peak times. It's also popular with folks just out of Brixton prison, according to a policeman we know. If you go and find it too busy, they're opening another in Stockwell.
