Looking for a share in Marylebone

As a westminster resident you can use the seymour leisure center for SO MUCH LESS than an normal gym.

Get a westminster rescard:  http://www.westminsteronline.org/~rescard/about_rescard.html

i use it for about 2.00 a time.... (which is good for me as i only go a few times a week).  No joiing fee or anything.  it's great.  has a pool, racketball etc.
