Kate Hudson revealed in her interview with ELLE magazine this month that she has been going to personal trainer Nicole Stuart for 15 years when she needs to get fit for a role.

Nicole specialises in Pilates and is based in LA with an A-list clientele; so chances are we'll never be able to reap the benefits of a one-to-one with the woman herself. But as a consolation, she has created four iPhone Apps each targeting a different body part - Hips, Abdominals, Arms and Butt. Nicole takes you through a series of exercises which are easy to do and each workout takes just 10 minutes to complete. "I love Nicole's app. I take it with me wherever I travel" says Kate.

Well, if it's good enough for an ELLE cover star...

QE Squared – Butts, Abdominals, Hips, Arms, £1.19 each or £3.49 for all four. Available from iTunes.
