There's almost no sport or daily physical activity that doesn't benefit from a stronger core—whether you’re running, carrying children or climbing the stairs—the core is a powerhouse, providing stability and support for your entire body. That's why it was always part of my routine when I was running marathons and weightlifting.
Now that I'm recovering from a protruding disc in my lower spine, I've come to realize how essential it is for injury recovery, too. My rehabilitation program is almost entirely focused on the three planes of core movement: sagittal (forward and backward), frontal (sideways) and transverse (rotational).
