There's a lot of buzz these days about building core strength. The core that's being referred to here is the abdomen and back, for the most part. When you strengthen the core, you dramatically strengthen your entire body and become better able to engage in virtually any kind of physical activity. Squats are famous for their core-building benefits, and many yoga poses are similar to squats. Yoga poses that are especially effective for building core strength include Side Plank, Boat and Dolphin Plank. By including these and similar poses in your routine, you're sure to start developing a stronger core in no time.
