I thought it was some sort of punishment centre for young people.
I have seen people being shouted at in Hyde Park, while running about, it frightens my dogs, perhaps you could try one of those. The 'instructors' dress in military fatigues, I find it odd that someone would pay to be shouted at.
I used to do British Military Fitness in Hyde Park when I lived in W2... I loved it! All the instructors are current or ex forces and it was a seriously knackering and hard hour long workout... despite all the shouting it was lots of fun with a great group atmosphere and much better than pounding on some treadmill. No connection apart from being a former satisfied user.
Hi I found something for Saturday mornings in this area. It was just through an ad - seems a little dodgy, like someone wanting to make a buck (or a pound!), but I shall give it a go. I shall report back if its good.
Hyde Park is a little far for me to go, though that is the type of thing I am looking for. I really lack the discipline and motivation to exercise!
