I blame that Jane Fonda. I’m not being funny girls but I can’t open a paper or turn on the TV without seeing yet another new workout DVD being promoted. Loads of them. From Coronation Street’s Beverley Callard and Debbie Rush, to Davina McCall, Rosemary Conley, Nadia Sawalha, Kerry Katona (sigh), Chantelle Houghton and the Strictly Come Dancers. And of course it’s already possible to buy dozens of others already on the market from those respected gurus of fitness and healthy living like er Jessie Wallace and Natalie Cassidy.
