Trying a new gym... for free

I arrived in Cheltenham a few days ago, and started looking for a gym immediately because I'm not working the moment (or working out!).

I came across a Free 5day guest membership for Fitness First:  http://www.fitnessfirst.co.uk/Campaign/Campaign-Form.aspx?fdCampaignId=776

I went yesterday and today, joined a dance class, watched a personalized tv while on the elliptical.  Tomorrow I'm going swimming.  Not sure how hard they will pressure me to join when the week is up...  But certainly worth a go!
