Looking for gym in London

Hi everyone,

I have recently moved to London to study for a year, and I am desperate to find a good gym. All gyms I've been to have been horrible! (No smith, only light dumbells etc.) I live in south west central London (Belgravia). Would prefer a gym nearby, but if not available, I guess I'll just have to travel.

Hope anyone can help me with this, since I'm anxious to get training again! Since I'm new to the city, would you please be so kind and provide a detailed description on how to get to the gyms?

Hoping for answers!

Anyone?
