The Tower Room in Mayfair was the townhouse's back bedroom. It holds four towers, two chairs and a ladder barrel, and it is the room members ask for by name. I think this is because it is the room where the method stops being about the reformer.
The tower work is spring work done vertically: standing, kneeling, hanging, lying with the legs in the air. It asks the body to organise against gravity rather than against a carriage, and it is unforgiving of cheating. On a reformer you can hide. On a tower, a leg spring will tell you, quickly and without malice, exactly where your hip is.
We keep the room to four. There is no music and the window looks onto the garden. A session lasts fifty-five minutes and most members are quiet for all of it. It is not a spa. It is a room where people work very hard at doing less, and the waiting list is a good sign that London understands the difference.
