Central London (UK) personal trainer prices?

JCLondonUK

Hi all,

I joined a gym yesterday, and am very happy with the deal I got. But I've been paying attention to the advice on the boards, and would like to start strength training. The gym has machine weights, and a large free weights section, but I'm a complete ignoramus about how to get started, and I think some personal trainer sessions would help. Can anyone advise on how much personal trainer sessions should cost in central London? And how many would I need to get me up and lifting?

Thanks in advance :-)
