The 38-year-old actress has been working with personal trainer Tracy Anderson for the last few years now and she has now come up with a new routine called Metamorphosis.
She said: 'By now, I think you all know how amazing I think my trainer, partner and friend Tracy Anderson is, how she kicked my twice pregnant ass into shape, and keeps taking me to new levels.
'Tracy's dream has always been able to make her ingenious customised-to-your-problem-areas program available to any woman who is up for the challenge - and now she has.'
