Lisa Rinna is yet another celebrity who swears by the yoga sessions. Without these, perhaps the lady would not be as fit as she is today. Indeed, it is the various yoga postures that deserve all the credit for the fab body that Rinna can boast of. In fact, with yoga as the center of her fitness regimen, Rinna need not depend on crazy diets and extreme fitness routines to maintain her beautiful self. All she needs to do is to be regular with her yoga postures, that are all pretty simple to perform, and there is no way that Rinna will put on weight or add unwanted flabs to her shapely body.
