Who says you need a fancy gym to get fit? These 5 workout programs have been deemed essentials in any at-home gym (and by gym we mean your living room, of course!).

 CrossFit: It might be safe to say that CrossFit was one of the most buzzed about workouts of the year... and with good reason.

Flat Yoga Abs: Jennifer Aniston has recently been crowned "the sexiest woman of all-time." One secret to her hot look: her yoga instructor Mandy Ingber who shared 8 yoga moves for sexy abs with SELF.

Core Fusion Cardio-Pure Intensity DVD: A must-have DVD from 2011, this workout is a perfect fusion of yoga and boot camp. An exercise you can expect to see make multiple appearances: the plank!
