This is the best Mummy Tummy DVD out there! I am the owner of Bella Bellies Studio in Hoboken, NJ and I recommend this to all my clients because, simply said, it works. As a pilates, yoga, gyrotonic, cardio and strength training instructor I have found this method (complimented with proper diet and cardio) to be the best method of core training. In fact, most of these exercises are incorporated into physical therapy programs for spine rehabilitation or general core strengthening. Client after client I have seen results.
Warm regards,
A.
