Mayfair Gym

I'm looking to join a gym in the St James / Mayfair has personal trainers.

Would like - a gym that I can do without a membership month month contract or somewhere I can go only for personal training (and not to use the facilities on a daily basis).

Suggestions?

Take a look on google for:

guns
Fitness
Fitness First
etc.

call them and see if you can negotiate one month against month. could cost you a bit more than normal though.
