A study published in 2016 found that the area in the primary motor cortex linked to the axial body muscles (our core) is directly connected to the adrenal glands. Work your core, decrease the stress response. Yoga, Pilates, planking . . . it will all build the right muscles—physical and mental. It makes sense when you think that we’ve always known the inverse: that a stooped posture from poor core strength is a sign of angst in a person.
