Weight / Fat loss

Any gym recommendations around the Goodge St/Tottenham court road area? I am particularly interested in somewhere that might have equipment like rings or TRX stuff and maybe a pool. I can't lift weights properly due to my hip being messed up by a previous powerlifting habit.

YMCA just off TCR?
