If you’ve been following trends in exercise and fitness over the past few years, you've probably heard the phrase "core strength." In anatomy, the core refers to the body or trunk (minus the legs and arms). Core strength supports the spine, improves body control and balance, and increases power and improves athletic performance.

Core strength develops your center of power. Though it’s the most important element of a stable body, assuring the transfer of energy during normal fitness and exercise, many people pay little attention to core strength because there's nothing flashy about it.
