apCertified yoga instructor Christa Janinea, 500 E-RYT, is here with a 10-minute yoga flow that will help you build major core strength. Janine, who's joined by class members Bianca Caceresa and Phillip Andersona, starts the class by leading you through a quick warmup that will wake up your body and prepare your abs for the challenge ahead. You'll make your way through moves like planks, bear holds, and flutter kicks that target all the muscles in your abs as well as your lower back and pelvic floor - hey, they're part of your core, too! This routine can be done anywhere - all you need is a mat to get started.pbr pDon't miss new episodes of Class Fitsugar every Sunday and Wednesday on the POPSUGAR Fitness YouTube channela.
