The 50 Best Fitness Essentials

Yoga: the Path to Holistic Health, by BKS Iyengar

Do yoga if you want to sleep better, feel happier and live longer. Mandie recommends this book for checking your form between classes. "Even though I do Iyengar yoga twice a week, I go back to this book time and again to help perfect my poses," she says. "The 360-degree views of models in the final postures have been invaluable. It's one of the most comprehensive yoga books out there, with everything from advice on how to use the props correctly to specialist poses for specific health problems."
