Davina McCall

Our guest this week is the wonderful Davina McCall - over her decades in the public eye, we've known Davina in many guises - as MTV presenter, Big Brother queen and now fitness expert. We met her in a rather echoey north London gym where she was working with F&F to launch the new Activewear collection, which is available in select Tesco stores from January 1. As well as giving advice on fitness though, Davina talked brilliantly about ageing, putting in the effort and mothering teenagers.
